This will only work for the Arrow IPC format, not for Parquet, because Parquet uses the raw LZ4 format instead of the framed format. Still to figure out: - [ ] Do we need to add tests to test if setting the compression level works as intended? (Or is this already covered by tests for the other formats that support levels) - [ ] Figure out the raw format for Parquet files The raw format does not support the compression level, but supports an acceleration value. This value works in opposite direction; increasing it speeds up the compression in expense of the ratio. The value can be set from 1 to 65537, so that's also completely different from the compression level in the framing format (1 to 12). -- This is an automated message from the Apache Git Service.
