## Summary * Add a range writer for uint16 and uint32 take indices. * Use it when a filter block or bitmap run is fully selected. * Keep the scalar path for mixed blocks. * Add benchmarks for dense, clustered, alternating, short, and nullable filters. ## Benchmark On an Apple M1 Pro, the 1M-row all-selected case improved from about 3.0 ms to 0.5 ms locally. Fragmented filters stayed close to the baseline. ## Tests * `go test ./arrow/compute/internal/kernels ./arrow/compute` * `go test -race ./arrow/compute/internal/kernels ./arrow/compute` * Full package test run passed with the local Parquet test data checkout, excluding the CSV example that needs a separate Arrow CSV fixture. -- This is an automated message from the Apache Git Service.
