> Enable block size support in ParquetIO
> --------------------------------------
>
> Key: BEAM-4383
> URL: https://issues.apache.org/jira/browse/BEAM-4383
> Project: Beam
> Issue Type: Improvement
> Components: io-ideas, io-java-parquet
> Reporter: Lukasz Gajowy
> Priority: P3
>
> Parquet API allows block size support, which can improve IO performance when
> working with Parquet files. Currently, the ParquetIO does not support it at
> all so it looks like a room for improvement for this IO.
