> Can we support aggregate pushdown with all the data types? For example, aggregating decimal values seems to have different behaviours between database implementations. >> Sorry I am not familiar with this. Could you please give me an example of the different implementations? For example, since PostgreSQL can have pretty large scale/precision in numeric, I think partial aggregated values can go over the value range of Spark decimals. So, I'm not sure that we can keep the same behaviour between with/without aggregate pushdown. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
