Add way to disables statistics on a per column basis

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.

Inizia leggendo i file allegati NoOpStatistics.java e add_config_to_opt-out_of_a_column's_statistics.patch, quindi traccia il modo in cui le statistiche si accumulano in BlockMetaData prima della serializzazione del footer. Il lavoro è completo quando viene fornito un modo per disabilitare le statistiche per colonna, così che le colonne BINARY di grandi dimensioni non accumulino più valori min/max causando errori OutOfMemory.
