Michal Zaborec commented on ARROW-18142:
----------------------------------------
The whole interaction with `ArrowWriter` looks weird. It seems that newly
allocated compressed buffers aren't closed at all.
> [Java] Compression closes uncompressed buffers
> ----------------------------------------------

> Key: ARROW-18142
> URL: https://issues.apache.org/jira/browse/ARROW-18142
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java
> Affects Versions: 9.0.0
> Reporter: Michal Zaborec
> Priority: Major
>
> _AbstractCompressionCodec_ closes underlying _uncompressedBuffer_ which leads
> to closed buffers in _VectorSchemaRoot_ via {_}VectorUnloader{_}. There isn't
> such behavior in _NoCompressionCodec_ passing underlying buffers untouched.
