swuferhong opened a new issue, #621: URL: https://github.com/apache/arrow-java/issues/621
### Describe the enhancement requested Currently, to do compression for one `ArrowRecordBatch`, in `VectorUnloader`, it will separately compress each `ArrowBuffer` within the `FieldVector` instead of compress at the `FieldVector level`. From the compression rate perspective, larger batches generally result in higher compression rates. Additionally, calling `compress(BufferAllocator allocator, ArrowBuf uncompressedBuffer)` multiple times may consume more CPU than call once. Therefore, I would like to ask if there will be support for overall compression at the `FieldVector level`, which could improve the compression ratio without affecting the ability to read individual columns. -- This is an automated message from the Apache Git Service.
