------------------------------------
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.
