enhance: move jemalloc_stats from pkg to internal/util/segcore (#46560)
Related to #46133

Move jemalloc_stats.go and its test file from pkg/util/hardware to
internal/util/segcore. This is a more appropriate location because:
- jemalloc_stats depends on milvus_core C++ library via cgo
- The pkg directory should remain independent of internal C++
dependencies
- segcore is the natural home for core memory allocator utilities

## Summary by CodeRabbit

* **Refactor**
* Improved internal code organization by reorganizing memory statistics
collection infrastructure for better maintainability and modularity. No
impact on end-user functionality or behavior.

fix: unify ro node handling to avoid balance channel task stuck (#46440)
issue: #46393

RO node can be created from two sources: stopping a QueryNode or replica
node transfer (e.g., suspend node). Before this fix, there were two
defects and one constraint that caused a deadlock:

Defects:
1. LeaderChecker does not sync segment distribution to RO nodes
2. Scheduler only cancels tasks on stopping nodes, not RO nodes

Constraint:
- Balance channel task blocks waiting for new delegator to become
serviceable (via sync segment) before executing release action

Deadlock scenario:
When target node becomes RO node (but not stopping) during balance
channel execution, the task gets stuck because:
- Cannot sync segment to RO node (defect 1) -> task blocks
- Task is not cancelled since node is not stopping (defect 2)

PR #45949 attempted to fix defect 1 but was not successful.

This PR unifies RO node handling by:
- LeaderChecker: only sync segment distribution to RW nodes
- Scheduler: cancel task when target node becomes RO node
- Simplify checkStale logic with unified node state checking

feat: Add nullable vector support for proxy and querynode (#46305)
related: #45993 

This commit extends nullable vector support to the proxy layer,
querynode,
and adds comprehensive validation, search reduce, and field data
handling
    for nullable vectors with sparse storage.
    
    Proxy layer changes:
- Update validate_util.go checkAligned() with getExpectedVectorRows()
helper
      to validate nullable vector field alignment using valid data count
- Update checkFloatVectorFieldData/checkSparseFloatVectorFieldData for
      nullable vector validation with proper row count expectations
- Add FieldDataIdxComputer in typeutil/schema.go for logical-to-physical
      index translation during search reduce operations
- Update search_reduce_util.go reduceSearchResultData to use
idxComputers
      for correct field data indexing with nullable vectors
- Update task.go, task_query.go, task_upsert.go for nullable vector
handling
    - Update msg_pack.go with nullable vector field data processing
    
    QueryNode layer changes:
    - Update segments/result.go for nullable vector result handling
- Update segments/search_reduce.go with nullable vector offset
translation
    
    Storage and index changes:
- Update data_codec.go and utils.go for nullable vector serialization
- Update indexcgowrapper/dataset.go and index.go for nullable vector
indexing
    
    Utility changes:
- Add FieldDataIdxComputer struct with Compute() method for efficient
      logical-to-physical index mapping across multiple field data
- Update EstimateEntitySize() and AppendFieldData() with fieldIdxs
parameter
    - Update funcutil.go with nullable vector support functions

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **New Features**
* Full support for nullable vector fields (float, binary, float16,
bfloat16, int8, sparse) across ingest, storage, indexing, search and
retrieval; logical↔physical offset mapping preserves row semantics.
  * Client: compaction control and compaction-state APIs.

* **Bug Fixes**
* Improved validation for adding vector fields (nullable + dimension
checks) and corrected search/query behavior for nullable vectors.

* **Chores**
  * Persisted validity maps with indexes and on-disk formats.

* **Tests**
  * Extensive new and updated end-to-end nullable-vector tests.

enhance: map multi row groups into one cache cell (#46249)
issue: #45486

Introduce row group batching to reduce cache cell granularity and
improve
memory&disk efficiency. Previously, each parquet row group mapped 1:1 to
a cache
cell. Now, up to `kRowGroupsPerCell` (4) row groups are merged into one
cell.
This reduces the number of cache cells (and associated overhead) by ~4x
while
maintaining the same data granularity for loading.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **Refactor**
* Switched to cell-based grouping that merges multiple row groups for
more efficient multi-file aggregation and reads.
* Chunk loading now combines multiple source batches/tables per cell and
better supports mmap-backed storage.

* **New Features**
* Exposed helpers to query row-group ranges and global row-group offsets
for diagnostics and testing.
* Translators now accept chunk-type and mmap/load hints to control
on-disk vs in-memory behavior.

* **Bug Fixes**
* Improved bounds checks and clearer error messages for out-of-range
cell requests.

Add manifest-based data loading path for optional fields in
`cache_opt_field_memory_v2`. When a manifest file is provided in the
config, the function now retrieves field data directly from the manifest
using `GetFieldDatasFromManifest` instead of reading from segment insert
files. This enables storage v2 compatibility for building indexes with
optional fields.

feat: impl ComputePhraseMatchSlop for compute min slop for phrase match query (#45892)
issue: https://github.com/milvus-io/milvus/issues/45890

ComputePhraseMatchSlop accepts three pararms:
1. A string: query text
2. Some trings: data texts
3. Analyzer params,

Slop will be calculated for the query text with each data text in the
context of phrase match where they are tokenized with tokenizer with
analyzer params.

So two array will be returned:
1. is_match: is phrase match can sucess
2. slop: the related slop if phrase match can sucess, or -1 is cannot.

fix: [skip e2e] resolve flaky TestKeyLockDispatcher unit test (#46454)
Related to #46453

The test was flaky because Submit() returns a Future and executes
asynchronously. The test was setting sig=true immediately after Submit()
returned, but the task's Run() might not have completed yet, causing
mock expectation failures.

Fix by calling future.Await() to wait for task execution to complete
before signaling. Also remove dead commented code.

feat: query coord support segment reopen when manifest path changes (#46394)
Related to #46358

Add segment reopen mechanism in QueryCoord to handle segment data
updates when the manifest path changes. This enables QueryNode to reload
segment data without full segment reload, supporting storage v2
incremental updates.

Changes:
- Add ActionTypeReopen action type and LoadScope_Reopen in protobuf
- Track ManifestPath in segment distribution metadata
- Add CheckSegmentDataReady utility to verify segment data matches
target
- Extend getSealedSegmentDiff to detect segments needing reopen
- Create segment reopen tasks when manifest path differs from target
- Block target update until segment data is ready

enhance: support AckSyncUp for broadcaster, and enable it in truncate api (#46313)
issue: #43897
also for issue: #46166

add ack_sync_up flag into broadcast message header, which indicates that
whether the broadcast operation is need to be synced up between the
streaming node and the coordinator.
If the ack_sync_up is false, the broadcast operation will be acked once
the recovery storage see the message at current vchannel, the fast ack
operation can be applied to speed up the broadcast operation.
If the ack_sync_up is true, the broadcast operation will be acked after
the checkpoint of current vchannel reach current message.
The fast ack operation can not be applied to speed up the broadcast
operation, because the ack operation need to be synced up with streaming
node.
e.g. if truncate collection operation want to call ack once callback
after the all segment are flushed at current vchannel, it should set the
ack_sync_up to be true.

TODO: current implementation doesn't promise the ack sync up semantic,
it only promise FastAck operation will not be applied, wait for 3.0 to
implement the ack sync up semantic. only for truncate api now.

enhance: support useLoonFFI flag in import workflow (#46363)
Related to #44956

This change propagates the useLoonFFI configuration through the import
pipeline to enable LOON FFI usage during data import operations.

Key changes:
- Add use_loon_ffi field to ImportRequest protobuf message
- Add manifest_path field to ImportSegmentInfo for tracking manifest
- Initialize manifest path when creating segments (both import and
growing)
- Pass useLoonFFI flag through NewSyncTask in import tasks
- Simplify pack_writer_v2 by removing GetManifestInfo method and relying
on pre-initialized manifest path from segment creation
- Update segment meta with manifest path after import completion

This allows the import workflow to use the LOON FFI based packed writer
when the common.useLoonFFI configuration is enabled.

feat: support reopen segment for data/schema changes (#46359)
issue: #46358

This PR implements segment reopening functionality on query nodes,
enabling the application of data or schema changes to already-loaded
segments without requiring a full reload.

### Core (C++)

**New SegmentLoadInfo class**
(`internal/core/src/segcore/SegmentLoadInfo.h/cpp`):
- Encapsulates segment load configuration with structured access
- Implements `ComputeDiff()` to calculate differences between old and
new load states
- Tracks indexes, binlogs, and column groups that need to be loaded or
dropped
- Provides `ConvertFieldIndexInfoToLoadIndexInfo()` for index loading

**ChunkedSegmentSealedImpl modifications**:
- Added `Reopen(const SegmentLoadInfo&)` method to apply incremental
changes based on computed diff
- Refactored `LoadColumnGroups()` and `LoadColumnGroup()` to support
selective loading via field ID map
- Extracted `LoadBatchIndexes()` and `LoadBatchFieldData()` for reusable
batch loading logic
- Added `LoadManifest()` for manifest-based loading path
- Updated all methods to use `SegmentLoadInfo` wrapper instead of direct
proto access

**SegmentGrowingImpl modifications**:
- Added `Reopen()` stub method for interface compliance

**C API additions** (`segment_c.h/cpp`):
- Added `ReopenSegment()` function exposing reopen to Go layer

### Go Side

**QueryNode handlers** (`internal/querynodev2/`):
- Added `HandleReopen()` in handlers.go
- Added `ReopenSegments()` RPC in services.go

**Segment interface** (`internal/querynodev2/segments/`):
- Extended `Segment` interface with `Reopen()` method
- Implemented `Reopen()` in LocalSegment
- Added `Reopen()` to segment loader

**Segcore wrapper** (`internal/util/segcore/`):
- Added `Reopen()` method in segment.go
- Added `ReopenSegmentRequest` in requests.go

### Proto

- Added new fields to support reopen in `query_coord.proto`

enhance: eliminate race condition in TestTargetObserver causing intermitt… (#46375)
This commit addresses an intermittent test failure in TestTargetObserver
with a mock panic error.

Problem:
--------
The original test TestTriggerUpdateTarget was a monolithic test that
cleared and recreated mock expectations mid-test execution. This created
a race condition:

1. Background goroutine in TargetObserver runs every 3 seconds, calling
broker.ListIndexes() and broker.DescribeCollection()
2. Test cleared all mock expectations at line 200 to prepare for next
phase
3. Test only re-mocked GetRecoveryInfoV2, leaving ListIndexes unmocked
4. If background goroutine triggered during this ~0.01s window (lines
200-213), it would call the unmocked ListIndexes() method, causing panic
and timeout

Error observed:
```
panic: test timed out after 10m0s
mock: I don't know what to return because the method call was unexpected.
Either do Mock.On("ListIndexes").Return(...) first, or remove the call.
```

Solution:
---------
Split the monolithic test into two independent test cases:

1. TestInitialLoad_ShouldNotUpdateCurrentTarget
   - Tests that CurrentTarget remains empty during initial load
   - Verifies the two-phase update mechanism works correctly

2. TestIncrementalUpdate_WithNewSegment
   - Tests incremental updates when new segments arrive
   - Properly sets up ALL required mocks before Eventually() calls
   - Lines 241-242 now include ListIndexes and DescribeCollection mocks

Benefits:
---------
- Eliminates race condition entirely (no mid-test mock clearing)
- Better test isolation and maintainability
- Clearer test intent with descriptive names
- Tests can run independently and in parallel
- Follows FIRST principles (Fast, Isolated, Repeatable, Self-validating,
Timely)

fix: ensure all channels synced before updating current target (#46348)
issue: #46087, #46327

The previous implementation only checked if there were any ready
delegators before updating the current target. This could lead to
partial target updates when only some channels had ready delegators.

This regression was introduced by #46088, which removed the check for
all channels being ready. This fix ensures that
shouldUpdateCurrentTarget returns true only when ALL channels have been
successfully synced, preventing incomplete target updates that could
cause query inconsistencies.

Added unit tests to cover:
- All channels synced scenario (should return true)
- Partial channels synced scenario (should return false)
- No ready delegators scenario (should return false)
