------------------------------------

             Summary: QuotaRefresherChore doesn't update the User RPC Throttle quota effectively
                 Key: HBASE-25078
                 URL: https://issues.apache.org/jira/browse/HBASE-25078
             Project: HBase
          Issue Type: Improvement
          Components: Quotas
            Reporter: Pankaj Kumar


Currently RegionServer record a user on their first RPC and trigger the QuotaCache refresh,


 https://github.com/apache/hbase/blob/8a6299bb387aaedcdab05224a462e63cd121fbb0/hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/QuotaCache.java#L136


And QuotaRefresherChore refresh quota periodically for those users who are recorded by RegionServer on their first RPC, 


https://github.com/apache/hbase/blob/8a6299bb387aaedcdab05224a462e63cd121fbb0/hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/QuotaCache.java#L284

 

So even though user quota is set but it will be updated when user send RPC. Here each user will get 1 extra RPC in each RegionServer life and same will continue when got restarted. 

 

We can enhance this by doing narrow scan on quota table to get the user specific quota
