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

## 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.

## Summary by CodeRabbit
* **Tests**
* Added a comprehensive highlighter test suite covering:

- Text-match and query-based highlighting, including BM25 and vector
interactions
- Sub-word, long-text/tag, case sensitivity, Chinese/multi-language
scenarios
- Error handling for invalid parameters, no-match cases, and other edge
conditions

When using brute-force search, the iterator results from multiple chunks
are merged; at that point, we need to pay attention to how the metric

issue: #45511
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

Replace the DeduplicateFieldData function with CheckDuplicatePkExist
that returns an error when duplicate primary keys are detected in the
same batch, instead of silently deduplicating.
Changes:
- Replace DeduplicateFieldData with CheckDuplicatePkExist in util.go
- Update upsertTask.PreExecute to return error on duplicate PKs
- Simplify helper function from findLastOccurrenceIndices to
hasDuplicates
- Update unit tests to verify the new error behavior
- Add Python integration tests for duplicate PK error cases

issue: #44320
This change adds deduplication logic to handle duplicate primary keys
within a single upsert batch, keeping the last occurrence of each
primary key.
Key changes:
- Add DeduplicateFieldData function to remove duplicate PKs from field
data, supporting both Int64 and VarChar primary keys
- Refactor fillFieldPropertiesBySchema into two separate functions:
validateFieldDataColumns for validation and fillFieldPropertiesOnly for
property filling, improving code clarity and reusability
- Integrate deduplication logic in upsertTask.PreExecute to
automatically deduplicate data before processing
- Add comprehensive unit tests for deduplication with various PK types
(Int64, VarChar) and field types (scalar, vector)
- Add Python integration tests to verify end-to-end behavior
