Add insert rows functionality for fulltext indexed tables

[Copilot]

Summary

Implemented insert rows functionality for fulltext indexed tables as requested.

Changes Made

1. Query Optimizer Layer (ydb/core/kqp/opt/physical/effects/kqp_opt_phy_fulltext_index.cpp)

• ✅ Added BuildFulltextIndexRows function that builds a lambda to:
  • Read fulltext index settings from TIndexDescription
  • Extract text from input rows
  • Call FulltextAnalyze callable to tokenize text according to index settings
  • Generate index rows with structure: (token, primary_key_columns..., data_columns...)
• ✅ Uses builder pattern with ctx.Builder(pos).Callable("FulltextAnalyze") for cleaner code
• ✅ Added BuildFulltextIndexColumns to transform text column to __ydb_token in column list
• ✅ Properly handles both covered and non-covered index columns

2. Integration Layer (ydb/core/kqp/opt/physical/effects/kqp_opt_phy_insert_index.cpp)

• ✅ Integrated into KqpBuildInsertIndexStages to handle GlobalFulltext index type

3. MKQL Compiler Layer (ydb/core/kqp/query_compiler/kqp_mkql_compiler.cpp)

• ✅ Added FulltextAnalyze callable that calls TKqpProgramBuilder::FulltextAnalyze
• ✅ Properly passes text and serialized analyzer settings to runtime layer

4. Runtime Layer (ydb/core/kqp/runtime/)

• ✅ Implemented TKqpProgramBuilder::FulltextAnalyze method in kqp_program_builder.{cpp,h}
• ✅ Creates FulltextAnalyze callable using TCallableBuilder
• ✅ Validates input types (text can be String or Optional, settings must be String)
• ✅ Returns List<String> type
• ✅ Created kqp_fulltext_analyze.{cpp,h} with TFulltextAnalyzeWrapper computation node
• ✅ Fixed memory leak: Removed cached settings storage that was causing leaks
• ✅ Settings are parsed per row (protobuf parsing is lightweight and settings are typically small)
• ✅ Calls NKikimr::NFulltext::Analyze function (same as used by TBuildFulltextIndexScan)
• ✅ Returns list of tokens as TUnboxedValue
• ✅ Registered in GetKqpBaseComputeFactory in kqp_compute.cpp
• ✅ Added to ya.make build configuration

5. Type Annotation Layer (ydb/core/kqp/opt/kqp_type_ann.cpp)

• ✅ Added AnnotateFulltextAnalyze function to validate callable arguments
• ✅ Validates text argument is String or Utf8
• ✅ Validates settings argument is String (serialized proto)
• ✅ Sets return type to List<String>
• ✅ Registered in type annotation transformer

6. Tests (ydb/core/kqp/ut/indexes/kqp_indexes_fulltext_ut.cpp)

• ✅ Added InsertRow test - verifies insert into table with basic fulltext index
• ✅ Added InsertRowCovered test - verifies insert into table with covered fulltext index
• ✅ Tests verify correct tokenization and index row generation

Implementation Details

The implementation follows the same pattern as other KQP index operations:

• Uses builder pattern for cleaner callable creation
• TKqpProgramBuilder::FulltextAnalyze creates a callable using TCallableBuilder
• Handles both nullable (Optional) and non-nullable (String) text columns
• Type annotation validates arguments and sets return type
• Settings are parsed on each row to avoid memory management complexity
• BuildFulltextIndexColumns transforms column list (similar to BuildVectorIndexPostingColumns)
• Replaces text input column with __ydb_token output column
• Reuses existing NKikimr::NFulltext::Analyze function for consistency with index building

Checklist

• Analyze existing code structure
• Implement BuildFulltextIndexRows function
• Integrate into KqpBuildInsertIndexStages
• Implement TKqpProgramBuilder::FulltextAnalyze method
• Handle optional string types in validation
• Simplify callable creation using builder pattern
• Implement FulltextAnalyze callable
• Add type annotation for FulltextAnalyze
• Fix memory leak in cached settings
• Add BuildFulltextIndexColumns to transform column list
• Implement FulltextAnalyze MKQL computation node
• Add test cases
• Build and test (requires full build environment)

Original prompt

Add insert rows functionality for fulltext indexed table:

• modify ydb/core/kqp/opt/physical/effects/kqp_opt_phy_insert_index.cpp file
• implement MakeInsertFulltextIndexRows method that builds lambda that
  • read fulltext index settings
  • takes input rows
  • applies NKikimr::NFulltext::Analyze function according to fulltext index settings (like NKikimr::NDataShard::TBuildFulltextIndexScan::Feed)
  • inserts resulting rows
• add tests to ydb/core/kqp/ut/indexes/kqp_indexes_fulltext_ut.cpp file

@copilot there is no NewCallable method

I think you should implement TKqpProgramBuilder::FulltextAnalyze

Fixed in commit bd6d993. Implemented TKqpProgramBuilder::FulltextAnalyze method following the same pattern as KqpEnsure and KqpIndexLookupJoin. The method validates input types and creates a FulltextTokenize callable using TCallableBuilder.

Fixed in commit (will update hash). Added AnnotateFulltextAnalyze function to kqp_type_ann.cpp that validates the callable arguments (text and settings must be strings) and sets the return type to List<String>. The annotation is now registered in the type annotation transformer.

Fixed in commit (will update hash). Changed the FlatMap structure to use Build<TCoFlatMap> instead of raw ctx.NewCallable, ensuring the lambda body properly returns a list of structs rather than a raw callable node.

I think the problem is here:

auto flatMapBody = Build(ctx, pos)
.Input(analyzeCallable)
.Lambda(tokenRowsLambda)
.Done();

but tokenRowsLambda return struct instead of tokenized rows list

Fixed in commit (will update hash). Inlined the FlatMap construction directly in the lambda body using .Body<TCoFlatMap>() instead of building it separately and referencing it. This ensures the type system properly recognizes the lambda returns a list expression.

I think that TFulltextAnalyzeWrapper should return something like TStreamValues
