[jira] [Created] (HBASE-28623) Scan with MultiRowRangeFilter very slow

chaijunjie created HBASE-28623:
----------------------------------

             Summary: Scan with MultiRowRangeFilter very slow
                 Key: HBASE-28623
                 URL: https://issues.apache.org/jira/browse/HBASE-28623
             Project: HBase
          Issue Type: Bug
          Components: Client
    Affects Versions: 2.4.14
            Reporter: chaijunjie


when we *scan* a big table({*}more than 500 regions{*}) with {*}MultiRowRangeFilter{*}, it is very slow...

it seems to {*}scan all regions{*}...

for example:

we scan 3 ranges..

startRow: 097_28220_ stopRow: 097_28220_~

startRow: 098_28221_ stopRow: 098_28221_~

startRow: 099_28222_ stopRow: 099_28222_~

and enable TRACE log in hbase client

we find the too many scans....
