Dremio configuration Constants / Documentation

Hi all,

I had a question about where I could manage the size of each block of parquet file. I found this key store.parquet.block-size and also this blog post https://www.dremio.com/tuning-parquet/.

So Iget new questions “where is the documentation of each key that help to configure and tune Dremio?”. In the file ExecConstants.java (https://github.com/dremio/dremio-oss/blob/master/sabot/kernel/src/main/java/com/dremio/exec/ExecConstants.java) we have many entries ! But there is no documentation where all that keys are referenced.

So could we have a documentation page where all Dremio cofiguration key are listed, detailed and described ?


Changing any of those values may result in unexpected behavior, which is why most of them are undocumented.

Hi !

Finally it appears that we can modify that configuration options with the command

ALTER SYSTEM SET `<<option>>` = <<value>>;

So, it’s why I think some documentation would be needed.
