> Project: Apache Hudi
> Issue Type: Sub-task
> Reporter: Sagar Sumit

> Priority: Blocker

> Fix For: 0.10.0

>
> After crossing a certain number of partitions, we observe performance
> degradation due to lower parallelism for snapshot query on COW tables in
> Presto. This does not happen for non-partitioned or tables with partioins in
> lower hundreds (~ 200-300).
> The issue is independent of the data size. It is more about partitions.
