--------------------------------
[~barrybecker4], Any more insights into this. I am going to have to do this
for about 3000 columns. Are you chunking your queries into smaller batches
like running multipleApproxQuantiles on batches of 100 at a time?
> org.apache.spark.sql.execution.stat.StatFunctions#multipleApproxQuantiles
> requires too much memory in case of many columns
