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

             Summary: Get rid of values deserialization in H2TreeIndex.getRowCount
                 Key: IGNITE-6702
                 URL: https://issues.apache.org/jira/browse/IGNITE-6702
             Project: Ignite
          Issue Type: Improvement
      Security Level: Public (Viewable by anyone)
            Reporter: Semen Boikov


It seems H2TreeIndex.getRowCount is called for 'select count(*) from x' queries, now it is implemented via BPlusTree.find(x, x) method which deserializes all values. Actually values are not needed there, need implement method on BPlusTree computing size without deserialization.
