## What this PR does
Removes two unused C++ third-party dependencies from `internal/core` to
reduce dependency count, comprehension cost, and link/build surface.
### rapidjson
Linked into `milvus_core` but has **zero `#include` usage** in the C++
sources (only a stale comment in `common/Json.h`). knowhere v3.0.3 and
milvus-storage do not depend on it. Removes the conan requirement,
`find_package(RapidJSON)`, and the link target.
### OpenDAL backend
Experimental `ChunkManager` backend gated behind `USE_OPENDAL`
(**default OFF**) — released binaries never built it. Removes
`OpenDALChunkManager`, the vendored OpenDAL Rust dependency, and all
`USE_OPENDAL` build plumbing (Makefile / core_build.sh /
3rdparty_build.sh / CMake). The Go-side `"opendal"` storageType value
remains a backward-compatible alias to the standard remote chunk
manager.
### Kept
`simde` is **not** removed — knowhere v3.0.3 requires it
(`find_package(simde REQUIRED)`, used in
`src/index/sparse/codec/varintdecode.c`).

#issue: #50182
Storage version compaction used to only care whether a segment had
reached the target storage version. That is not enough once StorageV3
segments can still have different column-group formats, because a
segment may already be V3 but still not match the format DataNode is
configured to write. This change lets DataCoord use the same compaction
path to refresh those segments by format as well.
The implementation adds a separate storage format compaction switch and
enables the policy when either version or format compaction is turned
on. For V3 segments, DataCoord now checks every field binlog format
against the configured target format, schedules only the segments that
actually need a rewrite, and keeps the existing health, L0, importing,
compacting, and snapshot-protection filters in place. External
collections are skipped so table-backed segments are not accidentally
pulled into this internal rewrite flow.
Segment metrics now include a segment format label in addition to state,
level, sorted status, and storage version. The metric update path also
tracks format transitions when binlogs are added or rewritten, including
legacy, unknown, and mixed-format cases, so DataCoord can report how
storage formats are distributed while segments move through refresh and
compaction.

## What was fixed
This fixes import two-phase commit timestamp handling so imported
segments keep the commit timestamp assigned by the import transaction
instead of being made visible at an unrelated later timestamp.
Changes included:
- Preserve import commit timestamps in DataCoord segment metadata.
- Broadcast import commit and rollback through DML channels so
downstream consumers observe the 2PC result consistently.
- Apply delete visibility in sealed segments based on the imported
segment commit timestamp.
- Carry the import transaction DML position needed for commit/rollback
propagation.
- Guard import in replicating clusters behind a disabled-by-default
config switch, and only allow `auto_commit=false` when that switch is
enabled.
- Downgrade only unsupported `GetSalvageCheckpoint` errors for
compatibility with older StreamingCoord implementations.
- Move import jobs to `Committing` before handling per-vchannel commit
acknowledgements, including the race where the vchannel commit is
handled before the DDL ack callback.
- Sync the generated `configs/milvus.yaml` entry for the new import
replication guard.

issue: #48359
This change makes Milvus automatically use CRC32C for S3 PutObject
requests when OpenSSL FIPS mode is active. In FIPS mode, checksum
choices are more constrained, so relying on the configured MinIO
checksum behavior can lead to requests using an algorithm that is not
acceptable in that runtime.
The implementation moves OpenSSL FIPS enablement into the shared
`pkg/util/fips` package and makes it return whether FIPS was actually
enabled. That lets startup code keep enabling OpenSSL FIPS as before,
while paramtable can also reuse the same state during config
initialization.
When FIPS is successfully enabled and `minio.ssl.useCRC32C` is still
false, Milvus now logs a warning and temporarily overrides the runtime
value to true. This keeps the user-facing config unchanged, but makes
the effective runtime behavior compatible with FIPS requirements.

## Summary
- Apply `common.arrow.ioThreadPoolCoefficient` /
`ioThreadPoolMaxCapacity` to DataNode at startup, mirroring the
QueryNode wiring from #49208/#49623. Without this, the paramtable keys
exist but have no effect on DataNode and the Arrow IO pool stays at
Arrow's hard-coded default of 8.
- Also call `initcore.InitArrowReaderConfig` so the parquet reader
range-coalescing limits (`hole`/`range` size) apply.
- Register paramtable watchers so capacity changes hot-reload without
restart, matching QueryNode behavior.
- Raise `dataCoord.import.fileNumPerSlot` default from 1 to 4 to reduce
per-import slot demand by 4x and leave more arrow IO pool headroom for
concurrent compactions on the same worker.
## Why
See #50098 for the full reproducer and analysis. Briefly: production
observed a 1.5M-row sort compaction taking >1 hour while the worker's
CPU sat at 12% and network at 14% of baseline — all 5 large
SortCompactions on different pods finished at nearly identical wall
times (variance < 1%), the classic shared-pool saturation signature.

issue: #50147
This change pulls the Vortex writer-format switch into its own focused
update. The goal is to make the insert data storage format configurable
from Milvus config, so we can turn Vortex on for CI validation without
mixing it with the unrelated AssertInfo cleanup from the previous PR.
The implementation adds dataNode.storage.format and wires it through
paramtable as DataNodeCfg.StorageFormat, with vortex as the current
default for this branch. When storagev2 builds milvus-storage
properties, it now passes the selected value through writer.format,
which matches the updated milvus-storage property contract.
This also updates the C++ writer path to use PROPERTY_WRITER_FORMAT
instead of the old PROPERTY_FORMAT key. That keeps the growing-segment
flush path aligned with the new storage property naming while still
forcing the TEXT flush writer to parquet where that path expects parquet
output.

## What changed
This patch adds a request-level CPU-factor limiter for QueryNode
delegator post-load work after worker `LoadSegments` returns.
The worker `LoadSegments` fan-out remains unchanged. The limiter covers
the delegator-side follow-up stages before the segment becomes visible:
- `LoadBloomFilterSet`
- `loadBM25Stats`
- `loadStreamDelete`
- distribution update
A refreshable config is added:
```text
queryNode.delegatorPostLoadConcurrencyFactor
```
Default factor is `1`, so the effective concurrency is CPU cores * 1.
## Why
Delegator post-load work can spike CPU when many load requests complete
around the same time. This is especially expensive when delete buffer
rows, loading segments, and historical BF entries multiply the amount of
BF work.

## Details
The `ioPoolSize` was calculated in `NewLoader()` and the config
`queryNode.ioPoolSize` was read to override it, but the resulting value
was never assigned to any struct field. The actual loading concurrency
is controlled by:
- **ConcurrencyLevel**: `min(CPUNum, segmentCount)` — hardcoded in
`segment_loader.go`
- **LoadPool**: `CPUNum * middlePriority` — controlled by
`common.threadCoreCoefficient.middlePriority`

## Summary
- New QueryNode toggle `queryNode.preferFieldDataWhenIndexHasRawData`
(default `false`) makes sealed retrieve serve scalar and vector fields
from resident column data instead of index-backed raw data, and the
loader keeps the column resident alongside the index on load/reload.
- Hot-path short-circuit: when the toggle is off, retrieve does not call
`HasFieldData` or take the segment's `shared_lock`, so the default
retrieve path is unchanged in cost.
- Observability: log at `InitQueryNode` when the toggle is on, calling
out the memory trade-off (field data + index both resident).
## Test plan
- [x] C++ unit:
`RetrieveScalarFieldFromColumnWhenIndexHasRawDataAndPreferFieldDataEnabled`
— seeds the scalar index with values deliberately desynchronized from
the column, then asserts the retrieved value equals the column value
under toggle=true. Positively proves the index branch is skipped rather
than just checking the API returns something.
- [x] Go unit (positive):
`TestLoadWithIndexPreferFieldDataWhenIndexHasRawData` — toggle=on,
asserts `HasFieldData=true`.
- [x] Go unit (negative): `TestLoadWithIndexSkipsFieldDataByDefault` —
toggle=off default, asserts `HasFieldData=false`. Guards the
memory-saving behavior existing deployments rely on.
- [ ] Integration smoke on local standalone.
## Trade-off
Enabling the toggle keeps both the raw field data and the index resident
in memory, roughly doubling the memory footprint for fields whose index
normally supplies raw data. The toggle is off by default, so no existing
deployment is affected.

## Summary
This PR ships two related commits:
1. **`enhance: fold calculate_size and write_to_target passes for
variable-length chunk writers`** — refactor String/JSON/Geometry chunk
writers from two Arrow passes (count + cache) to one Arrow pass that
fills a shared `offsets_` member. Eliminates per-row heap allocation (no
more `simdjson::padded_string` copies). `AssertInfo` guards `cursor <=
UINT32_MAX` before each narrowing cast so oversize chunks fail loudly
instead of silently wrapping.
2. **`enhance: configurable byte-size threshold for storage v2 cell
packing`** — replace the hardcoded `4 row groups per cell` constant with
a runtime-configurable byte-size target driven by
`queryNode.segcore.storageV2.cellTargetSizeBytes` (default `4 MiB`,
refreshable).
- At cell-build time, `rgs_per_cell = max(1, target /
avg_row_group_size)`, with cells never crossing file boundaries.
- Paramtable `Formatter` rejects non-positive values and falls back to 4
MiB with a warn log.
- Value pushed into segcore via a new CGO setter
(`SetStorageV2CellTargetSizeBytes`) on QueryNode startup and on
paramtable change, backed by an inline atomic in `GroupCTMeta.h`.
## Why
The fixed `4` constant does not scale across workloads: large row groups
make each cell too fat (coarse eviction, unpredictable memory), small
row groups waste cache slots and increase bookkeeping overhead. A
byte-target keeps cache cell footprint predictable regardless of parquet
row group layout, and gives operators a runtime tuning knob. Default 4
MiB preserves the prior `4 rgs × ~1 MiB/rg` footprint.
## Test plan
- [x] Dedicated `ComputeRowGroupsPerCell` unit tests with hardcoded
expected outputs pin helper behavior independently of the translator
integration tests.
- [x] `GroupChunkTranslatorTest` / `ManifestGroupTranslatorTest` read
`GetCellTargetSizeBytes()` so assertions track production.
- [ ] CI: `ci-v2/build-ut-cov`, `ci-v2/e2e-amd`
- [ ] Manual: toggle `queryNode.segcore.storageV2.cellTargetSizeBytes`
at runtime and confirm newly loaded segments observe the new pack size.

## Summary
Part 4/4 of the External Table Part 8 series. End-to-end optimization of
external segment load:
reduce the actual memory consumed during load via virtual system fields
and per-field column
projection, predict memory via row sampling injected as a synthetic
binlog so QueryNode can
reserve resources accurately, and drop the now-obsolete fragment row
mapping.
**Depends on [#49062](https://github.com/milvus-io/milvus/pull/49062)
(Part 2/4 control plane).**
Parallel to [#49172](https://github.com/milvus-io/milvus/pull/49172)
(Part 3/4 Iceberg) — no content dependency between 3/4 and 4/4.
This PR is stacked on top of #49062 — the diff includes both commits;
review the 4/4 commit in isolation via the "Commits" tab.
Related: [#45881](https://github.com/milvus-io/milvus/issues/45881)
(External Collection Lakehouse Integration tracking).
### Reduce load overhead
- **VirtualPKOffsetMap**: zero-storage OffsetMap for external
collections. Virtual PK = `(seg_id << 32) | offset`, so `pk→offset` is a
bit-extract, replacing `OffsetOrderedArray` — saves ~17 GB per 1B rows.
- **TimestampData**: compact timestamp container with lazy
materialization and a constant mode. External segments install constant
timestamps (all 0, rows always visible) — saves ~8 GB per 1B rows.
- **LoadColumnGroups per-field column projection**: split each column
group's fields into eager (`warmup=sync/async`) and lazy
(`warmup=disable`) subsets. Eager fields submit one task per group; lazy
fields submit one task per field so accessing one lazy field does not
co-load siblings from S3.
- Guard `reader_` assignment in `LoadColumnGroups` with `reader_mutex_`.
- Observability: `TaskStart / TaskDone / WaitStart / WaitOne /
WaitOneDone / WaitOneFail` with segment_id, cg index and elapsed time;
emit total elapsed on completion.
### Memory estimation via row sampling (fake binlog injection)
External table segments have no `BinlogPaths` and no format-level size
stats that can be trusted; inject a synthetic binlog so external
segments look like normal packed segments to downstream code.
- C++ `SampleExternalSegmentFieldSizes` (`external_utils_c.{cpp,h}`):
open a schemaless Reader against the manifest, `Take` N rows, measure
per-column Arrow buffer bytes/row.
- Go `SampleExternalFieldSizes` in `storagev2/packed` (shared by
QueryNode and DataNode).
- DataNode `buildFakeBinlogs()` at refresh time: pre-compute
`MemorySize` via sampling, synthesize `FieldBinlog` (`FieldID=0` with
`ChildFields`, allocator-assigned `LogID`, two IDs per segment), attach
to segment.
- DataCoord drops `ManifestPath` special-case checks; external segments
flow through the same code path as normal StorageV3 packed segments.
- `ManifestGroupTranslator` accepts `fallback_bytes_per_row`: when
format metadata reports `memory_size=0` for a cell, size it as
`cell_rows * bytes_per_row` instead of a 4KB last-resort.
- QueryNode `segment_loader` part 2.5: derive `fakeBinlogMemSize` from
`loadInfo.BinlogPaths`, set `EstimatedBytesPerRow = fakeBinlogMemSize /
numRows`, apply `externalRawDataFactor` only to the extra margin
(`factor - 1`), and subtract `fakeBinlogMemSize` under fully-lazy load.
- `isExternalCollectionLazyLoad` helper with companion test.
- `query_coord.proto` / `segcore.proto`: add `estimated_bytes_per_row`.
- Paramtable: external collection sample rows and rawDataFactor.
### Drop fragment row mapping
With fake binlogs in place, the fragment-level row index is no longer
consulted. Remove `SegmentRowMapping` / `FragmentRowRange` /
`NewSegmentRowMapping` / `GetFragmentByRowIndex`. The simplified task
tracks only segment-level state.

Compaction inherits StartPosition/DmlPosition from source segments via
getMinPosition without recalculating from actual data. The import
position bug (PR #47276) wrote wrong timestamps on imported segments,
and these wrong positions persist and propagate through compaction. L0
compaction then misses L1/L2 segments due to StartPosition mismatches,
causing zombie L0 segments and silent delete loss.
There is also a latent bug: DmlPosition in mix/clustering compaction
uses getMinPosition, but DmlPosition represents the latest entity
timestamp and should use max.

## Summary
Expose Arrow's internal IO thread pool capacity as a refreshable
paramtable knob so operators can raise it beyond Arrow's fixed default
of 8, independently of segcore `HIGH/MIDDLE` pools and
`minio.maxConnections`.
- New keys (both refreshable, `common` scope):
- `common.arrow.ioThreadPoolCoefficient` (default `0` → keep Arrow's
built-in default)
- `common.arrow.ioThreadPoolMaxCapacity` (default `0` → no cap)
- Effective size = `coefficient × CPU cores`, clamped by `maxCapacity`
when `> 0`.
- Wired through `init_c.{h,cpp}` + `initcore` + QueryNode paramtable
watcher; hot reloads apply without restart.
## Why
`GetIOThreadPool` runs the async range reads behind `ReadRangeCache`,
which is what actually issues S3 `GetObject` for storage v2 reads.
Milvus never calls `SetIOThreadPoolCapacity`, so this pool sticks at
Arrow's fixed default (`kDefaultNumIoThreads = 8` in arrow 17). Off-CPU
profiling on a QueryNode under heavy storage v2 load shows ~62% of
`HIGH`-pool wait time sitting on `curl_easy_perform -> poll` —
`HIGH`-pool threads blocked inside `ReadRangeCache::Wait` because
Arrow's IO pool cannot dispatch their range reads fast enough.
## Test plan
- [ ] CI: `ci-v2/build-ut-cov`, `ci-v2/e2e-amd`
- [ ] Manual: set `common.arrow.ioThreadPoolCoefficient=4` on a
QueryNode, confirm the `arrow io thread pool capacity set to N` log at
startup and that the pool is resized on subsequent config edits.
- [ ] Manual: re-run the storage-v2-heavy workload that produced the
off-CPU profile and confirm `curl_easy_perform -> poll` share drops from
~62%.

## Summary
Two improvements to BM25 stats memory accounting in idfOracle:
### 1. Per-entry estimate: 80 → 20 bytes/entry
The previous hardcoded `bm25StatsPerEntryBytes = 80` overestimates
`map[uint32]int32` memory by 4-7x. Empirical measurement on Go 1.24
(median of 5 runs, n ≥ 10K to avoid GC noise):
| n | heap delta | bytes/entry | overestimate vs 80 |
|---|---|---|---|
| 10K | 152 KB | 15.22 | 5.2× |
| 100K | 1.22 MB | 12.18 | 6.6× |
| 1M | 19.4 MB | 19.43 | 4.1× |
| 5M | 77.9 MB | 15.58 | 5.1× |
| 10M | 156 MB | 15.58 | 5.1× |
| 50M | 623 MB | 12.47 | 6.4× |
Steady-state cost oscillates between **12 and 19.5 bytes/entry**
depending on the swiss table fill ratio (peak ~19.5 right after a 2×
capacity grow, trough ~12 when near load factor 7/8).
Root cause: the original comment claimed "bucket overhead ~72B per
entry", but Go map buckets/groups hold 8 entries each, so amortized
overhead is ~10 bytes/entry, not 72.
**Fix**: lower the default to 20 (covers measured upper bound 19.5 with
small safety margin) and expose as
`queryNode.idfOracle.bm25StatsBytesPerEntry` (refreshable) for runtime
tuning.
### 2. Skip cgo Charge/Refund when tiered eviction is disabled
When `queryNode.segcore.tieredStorage.evictionEnabled = false` (the
default), the C++ caching layer's resource accounting is inert — no
eviction will be driven by it. The per-load `C.ChargeLoadedResource` /
`C.RefundLoadedResource` cgo calls are pure overhead in this case.
**Fix**: gate `syncResource` and `checkMemoryResource` on the eviction
flag. Skip entirely when eviction is off.
## Impact
- ~75% reduction in cache budget consumed by BM25 stats (when eviction
enabled)
- Eliminates per-segment cgo overhead in default deployments (eviction
off)
- Tunable per-entry estimate without redeploying
## Test plan
- [x] `TestIDFOracle` passes
- [x] `TestBM25Stats_MemSize` passes with the new configurable value
- [x] Verified memory measurement methodology with multiple sample sizes

## Summary
Part 1/4 of the External Table Part 8 series. Foundation layer for
external collections — delivers data-plane primitives that Parts 2–4
build on.
- **Cross-bucket external data source**: detect same-bucket prefix;
route non-matching paths through `extfs`.
- **Schemaless reader**: open reader with `nullptr` arrow schema +
explicit `needed_columns` projection instead of full pre-built arrow
schema.
- **Force nullable**: external user fields set to `nullable=true` so
Arrow buffers from external sources are consumed uniformly (`valid_data`
populated in `ArrowToDataArray`).
- **API cleanup**: replace `external_access_mode` string with
`use_take_for_output` bool.
- **Load optimization**: skip redundant S3 data pull during segment
load.
- **Shared helper**: new `pkg/util/externalspec` parsing package +
paramtable entries (100% test coverage).
- **Arrow codecs**: enable snappy/lz4 in Arrow build (fixes
[#48869](https://github.com/milvus-io/milvus/issues/48869)).

## Why split this way
This PR intentionally excludes the refresh pipeline
(manager/checker/inspector/task, schema DDL updater, refresh task
update, e2e refresh tests) — those land in Part 2/4. Each PR stays on a
single theme for reviewability.

This change increases the default value of deltalogMaxNum from 30 to
1000 in L0 compaction force trigger settings. This allows more segments
to be included in a single L0 compaction operation.
The change is safe because:
- We already have a maxSize limiter
(dataCoord.compaction.levelzero.forceTrigger.maxSize) that caps the
total size at 64MB, preventing excessive memory usage
- This only affects the maximum count allowed, not the minimum force
trigger threshold (deltalogMinNum: 10)
- Systems will still respect the size limit even if many small segments
are present

- Move snapshot privileges from Global level to Collection level
- Update client SDK and documentation for new API semantics
issue: #44358
issue: #47890
issue: #47883
issue: #47855
## Test plan
- [x] Unit tests for snapshot_meta (DropSnapshotsByCollection,
per-collection isolation, partial failure)
- [x] Unit tests for snapshot_manager (DropSnapshotsByCollection,
getDBCollectionIDs)
- [x] Unit tests for services (ListSnapshots/ListRestoreJobs with dbID,

## Note on skipped Python E2E tests
All 18 snapshot test classes in
`tests/python_client/milvus_client/test_milvus_client_snapshot.py` are
temporarily skipped with `@pytest.mark.skip`. Reason: this PR changes
snapshot APIs (DropSnapshot, DescribeSnapshot, RestoreSnapshot) to
require `collection_name` as a mandatory parameter, but the pymilvus SDK
used in CI has not been updated to pass this parameter yet. The tests
will be re-enabled once pymilvus SDK is updated to match the new API
contract.

## Summary
- Wraps `cm.Reader` (S3/MinIO HTTP body) with `bufio.NewReader` in
`streamOneFile` before creating the TeeReader
- `DeserializeFromReader` calls `binary.Read` which reads 4/8 bytes per
call; without buffering, each small read hits the remote reader
directly, causing excessive IO operations during preload parsing
- With `bufio.Reader` (default 4KB buffer), small reads are served from
the buffer, reducing remote IO to ~1 per 4KB
## Test plan
- [x] Existing `TestIDFOracle` tests pass
- [x] Verified via profiling that IO syscall count drops significantly
during BM25 preload

## Summary
- Add `common.visibilityFilterEnabled` toggle to bypass row visibility
filtering (timestamp, delete, and TTL) on querynode. When disabled, all
rows are returned regardless of insert/delete timestamps, improving
performance for workloads that don't need timestamp consistency.
- Add `common.bloomFilterEnabled` toggle to skip bloom filter/PK stats
loading on querynode, reducing memory for workloads without delete or
search-by-id. Delete forwarding falls back to broadcast mode when
disabled.
issue: #48703
## Test plan
- [ ] Unit tests for bloom filter disabled path
(`TestLoadSegmentsWithoutBloomFilter`, `TestLoadWithoutBloomFilter`)
- [ ] Unit tests for nil candidate broadcast in delete forwarding
- [ ] Unit tests for visibility filter bypass with
`visibilityFilterEnabled=false`
- [ ] Verify no nil pointer panics when bloom filter is disabled
- [ ] Integration test with `bloomFilterEnabled=false` and
`visibilityFilterEnabled=false`

## Summary
Prune sealed segments at the shard delegator layer using primary-key
(PK) predicate hints before dispatching search/query sub-tasks to worker
nodes. The delegator evaluates a lightweight PK predicate IR against
per-segment bloom-filter candidates it maintains in memory (`pkoracle`),
removing segments that are provably non-matching before any worker RPC
is issued.
issue: #47804
---
## Background
When a search/query request carries a PK predicate (e.g. `id == 5`, `id
IN [1,2,3]`, `1 < id < 100`), the delegator currently fans out the
request to all workers that own sealed segments, even if a worker's
segments provably contain no matching PKs. This causes unnecessary C++
vector-search kernel invocations, wasting CPU, I/O, and network.
The delegator already holds a `pkoracle.Candidate` for every sealed
segment it manages. Each candidate contains a bloom filter and min/max
PK statistics — sufficient to definitively exclude non-matching segments
before any sub-task is dispatched.
---
## Design
### 1. Proxy: \`pk_filter\` hint field
A new \`pk_filter int32\` field on \`SearchRequest\` /
\`RetrieveRequest\` carries a proxy-set hint:
| Value | Constant | Meaning |
|-------|----------|---------|
| \`0\` | \`PkFilterNotChecked\` | Old proxy / not analysed — delegator
attempts compilation (backward compat) |
| \`1\` | \`PkFilterHasPkFilter\` | Proxy confirmed optimisable PK
predicate exists |
| \`2\` | \`PkFilterNoPkFilter\` | Proxy confirmed no PK predicate —
delegator skips plan deserialization |
\`HasOptimizablePkPredicate\` in
\`internal/util/exprutil/expr_checker.go\` walks the expression tree:
TermExpr / UnaryRangeExpr / BinaryRangeExpr on a PK column, or an AND of
those, are considered optimisable. OR requires both sides to carry a PK
predicate; NOT is not optimisable.
**Backward compatible:** \`pk_filter\` wire-default is \`0\`
(NotChecked). Old proxies require no changes.
### 2. Delegator: \`PruneSealedSegmentsByPKFilter\`
Called in \`delegator.Search\`, \`delegator.Query\`, and
\`delegator.QueryStream\` after the sealed snapshot is obtained but
before \`organizeSubTask\` dispatches sub-requests:
1. If \`pkFilter == NoPkFilter\`, return immediately (no
deserialization).
2. Unmarshal plan, compile \`PKFilterExpr\` IR.
3. For each \`SnapshotItem\`, collect \`entry.Candidate\` as
\`PKFilterTarget\` and call \`CheckPKFilter\`.
4. Remove non-matching \`SegmentEntry\` in-place.
5. \`organizeSubTask\` automatically skips workers whose segment list is
now empty.
Controlled by \`queryNode.enableSegmentFilter\` (default \`true\`,
hot-reloadable).
### 3. PK Filter IR (\`pk_filter.go\`)
Typed expression tree compiled once per request in the delegator
package:
| Node | Semantics |
|------|-----------|
| \`pkFilterTermExpr\` | \`pk IN [v1, v2, ...]\` |
| \`pkFilterUnaryRangeExpr\` | \`pk op value\` |
| \`pkFilterBinaryRangeExpr\` | \`lo (</<=) pk (</<=) hi\` |
| \`pkFilterLogicalExpr\` | \`AND / OR\` |
| \`pkFilterUnsupportedExpr\` | fallback — keeps all segments |
### 4. \`PKFilterTarget\` interface (\`pkoracle\`)
\`BloomFilterSet\` implements \`GetMinPk()\` / \`GetMaxPk()\` (global
min/max across all stat blobs) and satisfies the \`PKFilterTarget\`
interface used by the IR evaluator.
### 5. Metrics
| Metric | Description |
|--------|-------------|
| \`milvus_querynode_segment_filter_total_segment_num\` | Total segments
considered |
| \`milvus_querynode_segment_filter_skipped_segment_num\` | Segments
pruned |
| \`milvus_querynode_segment_filter_hit_segment_num\` | Segments that
passed the filter |
### 6. Incidental cleanup
- Remove stale \`SearchRequest.PkFilter()\` / \`SetPkFilter()\`
accessors (no callers).
- Remove \`SearchTask.plan\` field and its \`PreExecute\`
deserialization (\`Execute\` never reads it; segcore re-parses from raw
bytes internally).
- Fix stale comment in \`QueryTask\`.
- Add Apache license header to \`segment_filter_helper.go\`.
