Wencong Liu commented on FLINK-30556:
-------------------------------------
Thanks [~luoyuxia]. As the ContinuousHiveSplitEnumerator can solve this
problem, I think it is enough. But I will try the implementation of iterator.
When the POC is completed, I can associate the PR with this issue. More
discussion can be proposed later. WDYT?
> Improve the logic for enumerating splits for Hive source to avoid potential

> Key: FLINK-30556
> URL: https://issues.apache.org/jira/browse/FLINK-30556
> Project: Flink
> Issue Type: Sub-task
> Components: Connectors / Hive
> Affects Versions: 1.16.0
> Reporter: luoyuxia
> Priority: Major
>
> Currently, when read hive source in batch mode, it'll first enumerate all
> split for the hive table. But when the table is large, the split will be too
> many which may well cause OOM. Some commuity users has also reported this
> problem.
> We need to optimize the logic for enumerating splits for hive table source to
> avoid potential OOM.
