### What Unify changing dictionary chunks incrementally in `unique`. ### Why The current path rebuilds and rehashes the accumulated dictionary for each changed chunk. ### Implementation - Keep one dictionary unifier and remap each chunk's indices. - Build the output dictionary once after all chunks. ### Benchmark - `BenchmarkUniqueChunkedChangingDictionaries/chunks=256`, Go 1.26.3, Apple M1 Pro, median of 5: 59.99 ms/op → 1.64 ms/op (36.6x); 117.7 MB/op → 1.82 MB/op (98.5% fewer bytes). -- This is an automated message from the Apache Git Service.
