Attachment: PHOENIX-5137-4.14-HBase-1.3.02.patch
> Index Rebuilder scan increases data table region split time
> -----------------------------------------------------------

> Key: PHOENIX-5137
> URL: https://issues.apache.org/jira/browse/PHOENIX-5137
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.1
> Reporter: Kiran Kumar Maturi
> Assignee: Kiran Kumar Maturi
> Priority: Major
> Attachments: PHOENIX-5137-4.14-HBase-1.3.02.patch,
> PHOENIX-5137-4.14-Hbase-1.3.01.patch, PHOENIX-5137-4.14-Hbase-1.3.01.patch

> [~lhofhansl] [~vincentpoon] [~tdsilva] please review
> In order to differentiate between the index rebuilder retries
> (UngroupedAggregateRegionObserver.rebuildIndices()) and commits that happen
> in the loop of UngroupedAggregateRegionObserver.doPostScannerOpen() as part
> of PHOENIX-4600 blockingMemstoreSize was set to -1 for rebuildIndices;
> {code:java}
> commitBatchWithRetries(region, mutations, -1);{code}
> blocks the region split as the check for region closing does not happen
> blockingMemstoreSize > 0
> {code:java}
> for (int i = 0; blockingMemstoreSize > 0 && region.getMemstoreSize() >
> blockingMemstoreSize && i < 30; i++) {
> try{
> checkForRegionClosing();
> ....
> {code}
> Plan is to have the check for region closing at least once before committing
> the batch
> {code:java}
> checkForRegionClosing();
> for (int i = 0; blockingMemstoreSize > 0 && region.getMemstoreSize() >
> blockingMemstoreSize && i < 30; i++) {
> try{
> checkForRegionClosing();
> ....
> {code}
> Steps to reproduce
> 1. Create a table with one index (startime)
> 2. Add 1-2 million rows
> 3. Wait till the index is active
> 4. Disable the index with start time (noted in step 1)
> 5. Once the rebuilder starts split data table region
> Repeat the steps again after applying the patch to check the difference.
