Hi, if you're open to try out something on your environment, could you please
try out SPARK-30946 and see how much it helps? You will need to back up your
checkpoint and "_spark_metadata" directory in output directory as SPARK-30946
will convert them to V2 format which is in proposal (no guarantee whether it
will be accepted, and when).
If you're not open to try out something but open to provide your metadata
files, please upload it somewhere and let me know. The latest 1 compact file
would be OK but it would be better if you can provide a set of one compact
interval (XXXX9.compact to XXX(X+1)8, 9 files). If you would like to do it
privately, please contact me via mail, kabhwan-opensource AT gmail.com
Thanks!

> When i use structured streaming parquet sink, I've noticed that the
> File-Sink-Log files keep getting bigger, they are in
> \{$checkpoint/_spark_metadata/}, i don't think this is reasonable.
> And when they merge files,task batches take longer to run, just like the
> screenshot below
