MisterWang reassigned HBASE-28783:
----------------------------------
Assignee: MisterWang
> Concurrent execution of normalizer operations on tables in
> RegionNormalizerWorker
> ---------------------------------------------------------------------------------
>
> Key: HBASE-28783
> URL: https://issues.apache.org/jira/browse/HBASE-28783
> Project: HBase
> Issue Type: Improvement
> Components: Normalizer
> Reporter: MisterWang
> Assignee: MisterWang
> Priority: Major
>
> Recently, I have been managing the large tables in the HBase cluster by
> enabling the normalizer to set the size of the regions and keep the number of
> regions within a reasonable range.
> The current code retrieves tables from RegionNormalizerWorkQueue and performs
> normalization operations on the tables in series. When there are multiple
> large tables in a cluster that need to be managed, the efficiency will be
> very low.
> I have confirmed that each split or merge plan generated by each table during
> the normalizer process will be limited by RateLimiter, so I think it is
> reasonable to perform table normalizers concurrently.
> In terms of implementation, create a thread pool for executing tasks in
> RegionNormalizerWorker, with a default value of 1 for the number of thread
> pools, and provide a parameter that can be configured to other values.
