Update milvus-storage from 91df193 to 839a8e5 to include
milvus-io/milvus-storage#342, which fixes a race condition in
S3GlobalContext initialization.
The fix moves the is_initialized_ flag update from before DoInitialize()
to after it completes. This ensures the initialization flag is only set
to true after the actual initialization is done, preventing potential
issues if DoInitialize() fails or if other code checks the flag during
initialization.

**Support specified version manifest write**
- Add `baseVersion` parameter to `NewPackedRecordManifestWriter` and
`NewFFIPackedWriter` to support writing manifest based on a specific
version instead of always overwriting the latest
- Add `manifestPath` tracking in `BulkPackWriterV2` to maintain manifest
state across writes
- Add `GetManifestInfo` method to parse existing manifest path and
extract base path and version
- Add `UpdateManifestPath` metacache action to track manifest path in
segment info
- Update `transaction_begin` FFI call to use the specified base version

For a vector field inside a STRUCT, since a STRUCT can only appear as
the element type of an ARRAY field, the vector field in STRUCT is
effectively an array of vectors, i.e. an embedding list.
Milvus already supports searching embedding lists with metrics whose
names start with the prefix MAX_SIM_.
This PR allows Milvus to search embeddings inside an embedding list
using the same metrics as normal embedding fields. Each embedding in the
list is treated as an independent vector and participates in ANN search.
Further, since STRUCT may contain scalar fields that are highly related
to the embedding field, this PR introduces an element-level filter
expression to refine search results.
The grammar of the element-level filter is:
element_filter(structFieldName, $[subFieldName] == 3)
where $[subFieldName] refers to the value of subFieldName in each
element of the STRUCT array structFieldName.
It can be combined with existing filter expressions, for example:
"varcharField == 'aaa' && element_filter(struct_field, $[struct_int] ==
3)"
A full example:
```
struct_schema = milvus_client.create_struct_field_schema()
struct_schema.add_field("struct_str", DataType.VARCHAR, max_length=65535)
struct_schema.add_field("struct_int", DataType.INT32)
struct_schema.add_field("struct_float_vec", DataType.FLOAT_VECTOR, dim=EMBEDDING_DIM)
schema.add_field(
"struct_field",
datatype=DataType.ARRAY,
element_type=DataType.STRUCT,
struct_schema=struct_schema,
max_capacity=1000,
)
...
filter = "varcharField == 'aaa' && element_filter(struct_field, $[struct_int] == 3 && $[struct_str] == 'abc')"
res = milvus_client.search(
COLLECTION_NAME,
data=query_embeddings,
limit=10,
anns_field="struct_field[struct_float_vec]",
filter=filter,
output_fields=["struct_field[struct_int]", "varcharField"],
)
```
TODO:
1. When an `element_filter` expression is used, a regular filter
expression must also be present. Remove this restriction.
2. Implement `element_filter` expressions in the `query`.

issue: #46087
The previous implementation checked if the total number of ready
delegators >= replicaNum per channel. This could cause target updates to
block indefinitely when dynamically increasing replicas, because some
replicas might lack nodes while the total count still met the threshold.
This change switches to a replica-based check approach:
- Iterate through each replica individually
- For each replica, verify all channels have at least one ready
delegator
- Only sync delegators from fully ready replicas
- Skip replicas that are not ready (e.g., missing nodes for some
channels)
This ensures target updates can proceed with ready replicas while
replicas that lack nodes during dynamic scaling are gracefully skipped.

Upgrade milvus-storage from 33bf815 to 91df193.
This includes the fix from milvus-io/milvus-storage#337, which resolves
a namespace collision where both Milvus and milvus-storage defined
identical credentials provider classes in the same namespace. Although
no compile-time redefinition errors occurred, the dynamic linker could
resolve to the wrong implementation at runtime, potentially causing
cloud authentication failures due to configuration mismatches.
The fix changes milvus-storage's credentials provider namespace to
`milvus_storage`, ensuring each project uses its own implementation.

Replace the heterogeneous insert data handling logic that modified
schema_ while holding a shared lock with an assertion. The previous
implementation had a concurrency bug where schema modification
operations were performed under a shared_lock, which violates mutex
semantics and can lead to data races.
Issue: #46225 reported two problems:
1. Schema modification under shared_lock (not exclusive lock)
2. Access to schema_ not protected by mutex in growing segment
The removed code attempted to handle "added fields" by:
- Adding new field to schema (schema_->AddField)
- Appending field metadata to insert_record_
- Setting default data for existing rows
All these write operations were performed while holding only a
shared_lock, which is incorrect since shared_locks are meant for
read-only operations.
This fix replaces the unsafe modification with an assertion that fails
if an unexpected new field is encountered in a growing segment with
existing data. The proper handling of schema changes should go through
the Reopen() path which correctly acquires a unique_lock before
modifying schema_.

our tantivy inverted index currently does not include item index if the
value is an array, thus we can't do `a[0] == 'b'` type of look up in the
inverted index. for such, we need to skip the index and use brute force
search.
we may improve our index in the future, so this is a temp solution

The test was failing intermittently because it didn't wait for the
pipeline to finish processing messages before exiting. The test sent a
message to the pipeline and immediately returned, causing the deferred
Close() to execute before ProcessInsert, ProcessDelete, and UpdateTSafe
could be called.
Fix by:
- Moving message construction before mock expectations setup
- Adding a done channel to synchronize on UpdateTSafe completion
- Waiting for the signal before test exits

Add collection-level granularity to the garbage collector pause/resume
mechanism. Previously, GC pause affected all collections globally. Now
operators can pause GC for specific collections while allowing other
collections to continue normal GC operations.
Changes:
- Add `pausedCollection` concurrent map to track per-collection pause
state
- Extend `Pause()` and `Resume()` methods with `collectionID` parameter
- Add `collectionGCPaused()` helper to check collection pause status
- Skip dropped segment recycling when collection GC is paused
- Update management API to accept optional `collection_id` query
parameter
- Add `GetInt64Value()` utility function for parsing int64 from KV pairs
- Maintain backward compatibility: collectionID <= 0 triggers global
pause
This provides DevOps with finer control over Milvus data lifecycle.

This fix addresses a bug where the segment loader incorrectly determined
whether scalar fields have raw data in their indexes, leading to
unnecessary field data loading or skipping indexed raw data retrieval.
- Build `field_ids` vector that handles both single field and column
group cases (when `child_fields_size() > 0`)
- Move the mmap setting and index_has_raw_data checks before the skip
decision, iterating over the correctly built `field_ids`
- Fix the boolean AND logic in both `Load()` and `LoadColumnGroup()` to
properly check if ALL fields in the group have raw data in their indexes
This bug was hiding the root cause of issue #46098, where QueryNode
panics when outputting timestamptz data from scalar index with raw data.
