[GitHub] [arrow] ebremer opened a new issue, #35824: Slow LZ4 compression using java Arrow 12.0.0

URL: https://github.com/apache/arrow/issues/35824
### Describe the bug, including details regarding any error messages, version, and platform.
500 MB of arrow data took a few hours to compress. A 5GB selection ran for a couple of days and did not complete. The one that did worked fine once it was done and I was able to read it back in and use it. Without compression, data writes out fine in a much shorter time frame for both. Using the following code to set up my writer:
```
ArrowFileWriter writer = new ArrowFileWriter(root, null, Channels.newChannel(fos), new HashMap<>(), IpcOption.DEFAULT, CommonsCompressionFactory.INSTANCE, CompressionUtil.CodecType.LZ4_FRAME));
```
Running code with:
```
java -version
openjdk version "17.0.7" 2023-04-18
OpenJDK Runtime Environment GraalVM CE 22.3.2 (build 17.0.7+7-jvmci-22.3-b18)
OpenJDK 64-Bit Server VM GraalVM CE 22.3.2 (build 17.0.7+7-jvmci-22.3-b18, mixed mode, sharing)
```

This is a known issue, there still isn't to my knowledge a canonical performance framed lz4 compressor/decompressor for java
