Re: [PR] GH-3083: Make DELTA_LENGTH_BYTE_ARRAY default encoding for binary [parquet-java]
jhorstmann commented on PR #3085:
URL: https://github.com/apache/parquet-java/pull/3085#issuecomment-2598424757
In my opinion the default should not be changed, but it would be really useful to allow users to configure the encoding per column, similar to how `BYTE_STREAM_SPLIT` is now handled in [`ParquetProperties`](https://github.com/apache/parquet-java/blob/master/parquet-column/src/main/java/org/apache/parquet/column/ParquetProperties.java#L500).
There might still be parquet readers with incomplete support for delta encodings, a simple version update could otherwise lead to problems which are only noticed much later.
