I'd be curious *why* the `WriteBuffered` was more performant than unbuffered, and if you'd be better served by just using https://pkg.go.dev/bufio#Writer as the underlying io.Writer rather than using the WriteBuffered for parquet (or using larger / different record sizes). In general, the unbuffered writing is going to be significantly more memory efficient unless you're trying to essentially collect multiple records into a single row-group or otherwise need to write to multiple columns before actually writing it to the parquet file. -- This is an automated message from the Apache Git Service.
