Description
When you write dataset with BINARY columns that can be fairly large (several Mbs) you can often end with an OutOfMemory error where you either have to:
- Throw more RAM
- Increase number of output files
- Play with Block size
Using a fork with increased checks frequency for row group size help but it is not enough. (PR: )
The OutOfMemory error is now caused due to the accumulation of min/max values for those columns for each BlockMetaData.
The "parquet.statistics.truncate.length" configuration is of no help because it is applied during the footer serialization whereas the OOM occurs before that.
I think it would be nice to have, like for dictionary or bloom filter, a way to disable the statistic on a per-column basis.
Could be very useful to lower memory consumption when stats of huge binary column are unnecessary.
