> Key: HUDI-5611
> URL: https://issues.apache.org/jira/browse/HUDI-5611
> Project: Apache Hudi
> Issue Type: Improvement
> Components: metadata
> Reporter: Ethan Guo

> Priority: Critical
> Fix For: 0.14.0

>
> We discover a performance issue with savepoint when the metadata table is
> enabled. It is due to unnecessary scanning of the metadata table when the
> number of partitions is large. When the metadata table is enabled, in the
> savepoint operation, for each partition, the metadata table is scanned, which
> leads to a lot of S3 requests. The solution is to batch the list calls of
> all partitions (HUDI-5485).
>
> We need to revisit metadata-table-based file listing calls in a similar
> fashion and replace them with batch lookup if needed.
