Expand description

Parquet compression codec interface.

Required methods

Compresses data stored in slice input_buf and writes the compressed result to output_buf. Note that you’ll need to call clear() before reusing the same output_buf across different compress calls.

Decompresses data stored in slice input_buf and writes output to output_buf. Returns the total number of bytes written.
