There was a problem hiding this comment.
The code changes look ok.
Do the Databricks product tests run automatically ?
Could you also add some rough benchmark results confirming improvement with new writer ?
New writer is an improvement regardless of perf numbers, because it avoids JNI for compression, and thus avoids OOM due to GCLocker.
They still don't exist, @findinpath @alexjo2144 are working on this. |

Is there a reason to leave the possibility to use the old writer ? |
just in case. we can remove it later. |
