## Summary * Build binary offsets with one linear pass over the values. * Keep full and subset offsets relative to the requested start. * Apply the same change to int32 and int64 offsets. ## Benchmarks Added benchmarks for full and subset copies with int32 and int64 offsets. The local runs use 1k and 100k unique values, plus empty and null values. The 100k-value cases were about 15% to 25% faster locally, with 0 allocs/op. ## Tests * `go test ./internal/hashing ./parquet/internal/encoding` * `go test -race ./internal/hashing` * 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.
