---------------------------------
Summary: [Performance] Lower parallelism with snapshot query on
COW tables in Presto
Key: HUDI-2599
URL: https://issues.apache.org/jira/browse/HUDI-2599
Project: Apache Hudi
Issue Type: Sub-task
Reporter: Sagar Sumit
Assignee: Sagar Sumit
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.
