Initialize the schema version field when creating a new collection
instance in QueryNode. The schema version is extracted from loadMetaInfo
and assigned to the collection, ensuring proper schema version tracking
and consistency across the distributed system.

kafka will auto reset the offset to "latest" if the offset is
Out-of-range. the recovery of milvus wal cannot read any message from
that. So once the offset is out-of-range, kafka should read from eariest

Fix a bug where DataNode panics when building json stats index throws an
exception before the writer is initialized. The destructor would call
Close() on an uninitialized packed_writer_ pointer, causing a null
pointer dereference.
Changes:
- Add null check for packed_writer_ before calling Flush() and Close()
- Prevents null pointer dereference in edge cases
- Ignore close status as this is a cleanup operation
This ensures safe cleanup even when initialization fails due to
exceptions.

Fix a bug where QueryNodeNumEntities metrics were not updated for
collections with zero segments, causing stale metrics when all segments
are flushed or compacted.
The previous implementation used separate loops: one to update size
metrics for all collections, and another to update num entities metrics
only for collections present in the grouped segments map. Collections
with no segments were skipped in the second loop, leaving their
NumEntities metrics stale.
Changes:
- Consolidate size and num entities metric updates into single loop
- Iterate over all collections instead of grouped segments
- Get collection metadata from manager instead of segment instances
- Correctly set NumEntities to 0 for collections with no segments
- Apply the same fix to both growing and sealed segment processing
- Add nil check for collection metadata before processing
This ensures all collection metrics are updated consistently, even when
segment count drops to zero.

This commit refactors the test MilvusClient wrapper to leverage Go's
embedding pattern and improves test organization with subtests.
**File**: `tests/go_client/base/milvus_client.go`
- **Use `typeutil.NewSet` for rate limiting**: Replace map-based
`rateLogMethods` with `typeutil.NewSet` for cleaner and more efficient
membership checking
- **Embed `*client.Client` directly**: Change `MilvusClient` structure
from wrapping the client as a field to embedding it directly
- **Remove ~380 lines of wrapper methods**: All wrapper methods
(database, collection, partition, index, read/write, RBAC, etc.) are now
unnecessary thanks to Go's embedding feature, which automatically
promotes embedded methods to the outer type
- **Simplify initialization**: Update `NewMilvusClient` and `Close` to
use embedded client directly
- **Fix typo**: Correct comment "Ike the actual method" → "Invoke the
actual method"
**File**: `tests/go_client/testcases/search_test.go`
- **Wrap assertions in subtests**: Each search expression test is now
wrapped in `t.Run()` with descriptive names
- **Dynamic subtest naming**: Format:
`expr={expression}_dynamic-{true/false}` for clear test identification

Add manifest_path field throughout the data path to support LOON Storage
V2 manifest tracking. The manifest stores metadata for segment data
files and enables the unified Storage V2 FFI interface.
Changes include:
- Add manifest_path field to SegmentInfo and SaveBinlogPathsRequest
proto messages
- Add UpdateManifest operator to datacoord meta operations
- Update metacache, sync manager, and meta writer to propagate manifest
paths
- Include manifest_path in segment load info for query coordinator
This is part of the Storage V2 FFI interface integration.

StringIndexSort now properly handles collections with all-null string
fields by:
- Removing the error thrown when unique_count is 0 in ParseBinaryData
- Adding alignment and padding support in mmap serialization (similar to
ScalarIndexSort)
- Separating data_size_ from mmap_size_ to correctly parse data without
reading padding
This fixes load collection timeout failures when all string field data
is null, particularly affecting STL_SORT and TRIE index types.

This commit introduces the foundation for enabling segments to manage
their own loading process by passing load information during segment
creation.
Changes:
C++ Layer:
- Add NewSegmentWithLoadInfo() C API to create segments with serialized
load info
- Add SetLoadInfo() method to SegmentInterface for storing load
information
- Refactor segment creation logic into shared CreateSegment() helper
function
- Add comprehensive documentation for the new API
Go Layer:
- Extend CreateCSegmentRequest to support optional LoadInfo field
- Update segment creation in querynode to pass SegmentLoadInfo when
available
- Add ConvertToSegcoreSegmentLoadInfo() and helper converters for proto
translation
Proto Definitions:
- Add segcorepb.SegmentLoadInfo message with essential loading metadata
- Add supporting messages: Binlog, FieldBinlog, FieldIndexInfo,
TextIndexStats, JsonKeyStats
- Remove dependency on data_coord.proto by creating segcore-specific
definitions
Testing:
- Add comprehensive unit tests for proto conversion functions
- Test edge cases including nil inputs, empty data, and nil array/map
elements
This is the first step toward issue #45060 - enabling segments to
autonomously manage their loading process, which will:
- Clarify responsibilities between Go and C++ layers
- Reduce cross-language call overhead
- Enable precise resource management at the C++ level
- Support better integration with caching layer
- Enable proactive schema evolution handling

We need to promise the state of wal consistent with the memory state of
streamingnode. So we don't allow the append operation can be cancelled
by the append caller to avoid leave a inconsistent state of alive wal.
The wal append operation can only be cancelled when the wal is shutting
down.

Previsouly, the parquet import is implemented based on that the STRUCT
in the parquet files is hanlded in the way that each field in struct is
stored in a single column.
However, in the user's perspective, the array of STRUCT contains data is
something like STRUCT_A:
for one row, [struct{field1_1, field2_1, field3_1}, struct{field1_2,
field2_2, field3_2}, ...], rather than {[field1_1, field1_2, ...],
[field2_1, field2_2, ...], [field3_1, field3_2, field3_3, ...]}.
This PR fixes this.

Optimize bitmap initialization in ScalarIndexSort range queries by using
adaptive strategy based on result density. When more than 50% of
elements match the range condition, initialize bitmap with all true
values and clear non-matching elements. Otherwise, use the original
approach of initializing with false and setting matching elements. Also
defer bitmap allocation until after early return checks to avoid
unnecessary memory allocation.
This optimization reduces bit operations for high-selectivity queries
while maintaining the same performance for low-selectivity queries.
