enhance: implement external collection update task with source change detection (#45690)
issue: https://github.com/milvus-io/milvus/issues/45691
Add persistent task management for external collections with automatic
detection of external_source and external_spec changes. When source
changes, the system aborts running tasks and creates new ones, ensuring
only one active task per collection. Tasks validate their source on
completion to prevent superseded tasks from committing results.

enhance: support manifest-based index building with Loon FFI reader (#45726)
This PR adds support for reading data from StorageV2 using manifest
files and the Loon FFI interface during index building, providing an
alternative to the traditional segment insert files approach.

Key changes:

Core C++ changes:
- Add SEGMENT_MANIFEST_KEY and LOON_FFI_PROPERTIES_KEY constants for
manifest handling
- Extend FileManagerContext to carry loon_ffi_properties for FFI
operations
- Update index_c.cpp to pass manifest and loon properties to file
managers for all index types (vector, JSON key, text)
- Implement GetFieldDatasFromManifest() in Util.cpp using Arrow C Stream
interface:
  * Create Arrow schema from field metadata
  * Initialize FFI reader with manifest content and storage properties
  * Import record batches from C data interface
  * Convert to FieldData for index building
- Update DiskFileManagerImpl and MemFileManagerImpl to support
manifest-based data reading with fallback to traditional paths

Loon FFI utilities (internal/core/src/storage/loon_ffi/):
- Add ToCStorageConfig() to convert StorageConfig to C-compatible
structure
- Implement GetManifest() to parse manifest JSON and retrieve column
groups via FFI
- Enhance MakePropertiesFromStorageConfig() integration

Storage V2 integration:
- Update milvus-storage dependency from 0883026 to 302143c for latest
FFI support

Protobuf changes:
- Add manifest field to BuildIndexInfo for passing manifest path to C++
layer

Configuration:
- Add common.storageV2.useLoonFFI config option (default: false) for
feature toggle

This change is part of issue #44956 to integrate the StorageV2 FFI
interface as the unified storage layer. The implementation maintains
backward compatibility by checking for manifest presence and falling
back to existing segment insert files approach when manifest is not
provided.

enhance: integrate Storage V2 FFI interface for unified storage access (#45723)
Related #44956
This commit integrates the Storage V2 FFI (Foreign Function Interface)
interface throughout the Milvus codebase, enabling unified storage
access through the Loon FFI layer. This is a significant step towards
standardizing storage operations across different storage versions.

1. Configuration Support
- **configs/milvus.yaml**: Added `useLoonFFI` configuration flag under
`common.storage.file.splitByAvgSize` section
- Allows runtime toggle between traditional binlog readers and new
FFI-based manifest readers
  - Default: `false` (maintains backward compatibility)

2. Core FFI Infrastructure

Enhanced Utilities (internal/core/src/storage/loon_ffi/util.cpp/h)
- **ToCStorageConfig()**: Converts Go's `StorageConfig` to C's
`CStorageConfig` struct for FFI calls
- **GetManifest()**: Parses manifest JSON and retrieves latest column
groups using FFI
  - Accepts manifest path with `base_path` and `ver` fields
  - Calls `get_latest_column_groups()` FFI function
  - Returns column group information as string
  - Comprehensive error handling for JSON parsing and FFI errors

3. Dependency Updates
- **internal/core/thirdparty/milvus-storage/CMakeLists.txt**:
  - Updated milvus-storage version from `0883026` to `302143c`
  - Ensures compatibility with latest FFI interfaces

4. Data Coordinator Changes

All compaction task builders now include manifest path in segment
binlogs:

- **compaction_task_clustering.go**: Added `Manifest:
segInfo.GetManifestPath()` to segment binlogs
- **compaction_task_l0.go**: Added manifest path to both L0 segment
selection and compaction plan building
- **compaction_task_mix.go**: Added manifest path to mixed compaction
segment binlogs
- **meta.go**: Updated metadata completion logic:
- `completeClusterCompactionMutation()`: Set `ManifestPath` in new
segment info
- `completeMixCompactionMutation()`: Preserve manifest path in compacted
segments
- `completeSortCompactionMutation()`: Include manifest path in sorted
segments

5. Data Node Compactor Enhancements

All compactors updated to support dual-mode reading (binlog vs
manifest):

6. Flush & Sync Manager Updates

Pack Writer V2 (pack_writer_v2.go)
- **BulkPackWriterV2.Write()**: Extended return signature to include
`manifest string`
- Implementation:
  - Generate manifest path: `path.Join(pack.segmentID, "manifest.json")`
  - Write packed data using FFI-based writer
  - Return manifest path along with binlogs, deltas, and stats

Task Handling (task.go)
- Updated all sync task result handling to accommodate new manifest
return value
- Ensured backward compatibility for callers not using manifest

7. Go Storage Layer Integration

New Interfaces and Implementations
- **record_reader.go**: Interface for unified record reading across
storage versions
- **record_writer.go**: Interface for unified record writing across
storage versions
- **binlog_record_writer.go**: Concrete implementation for traditional
binlog-based writing

Enhanced Schema Support (schema.go, schema_test.go)
- Schema conversion utilities to support FFI-based storage operations
- Ensures proper Arrow schema mapping for V2 storage

Serialization Updates
- **serde.go, serde_events.go, serde_events_v2.go**: Updated to work
with new reader/writer interfaces
- Test files updated to validate dual-mode serialization

8. Storage V2 Packed Format

FFI Common (storagev2/packed/ffi_common.go)
- Common FFI utilities and type conversions for packed storage format

Packed Writer FFI (storagev2/packed/packed_writer_ffi.go)
- FFI-based implementation of packed writer
- Integrates with Loon storage layer for efficient columnar writes

Packed Reader FFI (storagev2/packed/packed_reader_ffi.go)
- Already existed, now complemented by writer implementation

9. Protocol Buffer Updates

data_coord.proto & datapb/data_coord.pb.go
- Added `manifest` field to compaction segment messages
- Enables passing manifest metadata through compaction pipeline

worker.proto & workerpb/worker.pb.go
- Added compaction parameter for `useLoonFFI` flag
- Allows workers to receive FFI configuration from coordinator

10. Parameter Configuration

component_param.go
- Added `UseLoonFFI` parameter to compaction configuration
- Reads from `common.storage.file.useLoonFFI` config path
- Default: `false` for safe rollout

11. Test Updates
- **clustering_compactor_storage_v2_test.go**: Updated signatures to
handle manifest return value
- **mix_compactor_storage_v2_test.go**: Updated test helpers for
manifest support
- **namespace_compactor_test.go**: Adjusted writer calls to expect
manifest
- **pack_writer_v2_test.go**: Validated manifest generation in pack
writing

This integration follows a **dual-mode approach**:
1. **Legacy Path**: Traditional binlog-based reading/writing (when
`useLoonFFI=false` or no manifest)
2. **FFI Path**: Manifest-based reading/writing through Loon FFI (when
`useLoonFFI=true` and manifest exists)

enhance: add NewSegmentWithLoadInfo API to support segment self-managed loading (#45061)
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

feat: Geospatial Data Type and GIS Function support for milvus (#44547)
issue: #43427

This pr's main goal is merge #37417 to milvus 2.5 without conflicts.

# Main Goals

1. Create and describe collections with geospatial type
2. Insert geospatial data into the insert binlog
3. Load segments containing geospatial data into memory
4. Enable query and search can display  geospatial data
5. Support using GIS funtions like ST_EQUALS in query
6. Support R-Tree index for geometry type

# Solution

1. **Add Type**: Modify the Milvus core by adding a Geospatial type in
both the C++ and Go code layers, defining the Geospatial data structure
and the corresponding interfaces.
2. **Dependency Libraries**: Introduce necessary geospatial data
processing libraries. In the C++ source code, use Conan package
management to include the GDAL library. In the Go source code, add the
go-geom library to the go.mod file.
3. **Protocol Interface**: Revise the Milvus protocol to provide
mechanisms for Geospatial message serialization and deserialization.
4. **Data Pipeline**: Facilitate interaction between the client and
proxy using the WKT format for geospatial data. The proxy will convert
all data into WKB format for downstream processing, providing column
data interfaces, segment encapsulation, segment loading, payload
writing, and cache block management.
5. **Query Operators**: Implement simple display and support for filter
queries. Initially, focus on filtering based on spatial relationships
for a single column of geospatial literal values, providing parsing and
execution for query expressions.Now only support brutal search
7. **Client Modification**: Enable the client to handle user input for
geospatial data and facilitate end-to-end testing.Check the modification
in pymilvus.

The third PR of issue: https://github.com/milvus-io/milvus/issues/27467,
which completes M5, M6, M7, M8 described above.

## M8 Default Timezone

We will be able to use alter_collection() and alter_database() in a
future Python SDK release to modify the default timezone at the
collection or database level.

For insert requests, the timezone will be resolved using the following
order of precedence: String Literal-> Collection Default -> Database
Default.
For retrieval requests, the timezone will be resolved in this order:
Query Parameters -> Collection Default -> Database Default.
In both cases, the final fallback timezone is UTC.


## M5: Comparison Operators

We can now use the following expression format to filter on the
timestamptz field:

- `timestamptz_field [+/- INTERVAL 'interval_string'] {comparison_op}
ISO 'iso_string' `

- The interval_string follows the ISO 8601 duration format, for example:
P1Y2M3DT1H2M3S.

- The iso_string follows the ISO 8601 timestamp format, for example:
2025-01-03T00:00:00+08:00.

- Example expressions: "tsz + INTERVAL 'P0D' != ISO
'2025-01-03T00:00:00+08:00'" or "tsz != ISO
'2025-01-03T00:00:00+08:00'".

## M6: Extract

We will be able to extract sepecific time filed by kwargs in a future
Python SDK release.
The key is `time_fields`, and value should be one or more of "year,
month, day, hour, minute, second, microsecond", seperated by comma or
space. Then the result of each record would be an array of int64.



## M7: Indexing Support

Expressions without interval arithmetic can be accelerated using an
STL-SORT index. However, expressions that include interval arithmetic
cannot be indexed. This is because the result of an interval calculation
depends on the specific timestamp value. For example, adding one month
to a date in February results in a different number of added days than
adding one month to a date in March.

--- 

After this PR, the input / output type of timestamptz would be iso
string. Timestampz would be stored as timestamptz data, which is int64_t
finally.

enhance: Add granular flush targets support for FlushAll operation (#44234)
issue: #44156
Enhance FlushAll functionality to support targeting specific collections
within databases instead of only database-level flushing.

Changes include:

- Add FlushAllTarget message in data_coord.proto for granular targeting
- Support collection-specific flush operations within databases
- Maintain backward compatibility with deprecated db_name field

This enhancement allows users to flush specific collections without
affecting other collections in the same database, providing more precise
control over data persistence operations.

feat: support dropping index without releasing collection (#42941)
issue: #42942

This pr includes the following changes:
1. Added checks for index checker in querycoord to generate drop index
tasks
2. Added drop index interface to querynode
3. To avoid search failure after dropping the index, the querynode
allows the use of lazy mode (warmup=disable) to load raw data even when
indexes contain raw data.
4. In segcore, loading the index no longer deletes raw data; instead, it
evicts it.
5. In expr, the index is pinned to prevent concurrent errors.
