- Add BtreeGlobalIndexWriter for writing btree global index files - Fix AllNonNullRows() compilation errors: - Use GetLongCardinality() instead of Cardinality() - Use AddRange(Range(0, total_rows - 1)) instead of AddRange(0, total_rows) - Add unit tests for btree file footer, index meta, writer, and indexer - Add integration test for btree global index

- Add B-tree compatibility test to ensure data compatibility with Java implementation - Implement B-tree global index writer with proper file format - Add integration tests for B-tree global index - Refactor SST block footer to sort lookup store footer - Update file index reader to support B-tree format - Add comprehensive test data for compatibility verification Co-Authored-By: Claude Opus <noreply@anthropic.com>
- Change BIGINT from string format to 8-byte little-endian binary format - Change TINYINT from string format to 1-byte binary format - Change SMALLINT from string format to 2-byte little-endian binary format - Update compatibility test data to match new binary format

Impressive work on this complex feature. Thanks for the contribution — review coming up. |
1. Fix modernize-use-auto warnings - Replace explicit type declarations with auto when initializing with template casts - Fixed 13 warnings in btree_global_indexer.cpp - Fixed 5 warnings in btree_global_indexer_test.cpp 2. Fix AddressSanitizer alloc-dealloc-mismatch errors - Replace Bytes::AllocateBytes with std::make_shared<Bytes> - Avoid memory pool allocated objects being freed by operator delete - Fixed 13 memory allocation/deallocation mismatches 3. Fix UndefinedBehaviorSanitizer null pointer error - Add num_bytes > 0 check in MemorySegmentUtils::CopyToBytes - Avoid passing null pointer to memcpy when num_bytes is 0 4. Fix modernize-use-default-member-init warning - Use default member initializer for file_counter_ in btree_global_index_writer_test.cpp
