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

- move most cgo opeartions related to search/query into segcore package
for reusing for streamingnode.
- add go unittest for segcore operations.
