> REPL: Optimise partition loading during bootstrap
> -------------------------------------------------
>
> Key: HIVE-23521
> URL: https://issues.apache.org/jira/browse/HIVE-23521
> Project: Hive
> Issue Type: Improvement
> Reporter: Rajesh Balamohan
> Assignee: Rajesh Balamohan
> Priority: Major
> Attachments: HIVE-23521.1.patch

>
> When bootstrapping with large "REPL dump" with ~10K partitions, it starts
> executing "addPartition" in sequential manner and takes very long time as it
> communicates with HMS/registers partition etc for every call.

> [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/repl/bootstrap/load/table/LoadPartitions.java#L210]
> When bootstrap loading has to deal with DDL, it would be good to collate all
> partitions in single call to HMS. This would help in reducing overall runtime.
