Denis Magda created IGNITE-2751: ----------------------------------- Summary: GridH2TreeIndex.getRowCount unwraps objects' values that are not used later Key: IGNITE-2751 URL: https://issues.apache.org/jira/browse/IGNITE-2751 Project: Ignite Issue Type: Bug Affects Versions: 1.5.0.final Reporter: Denis Magda Priority: Critical Fix For: 1.6
If to run query like "SELECT COUNT(*) FROM table" then our implementation will perform a full scan filtering out entries that are not primary for a given node and will calculate only a number of primary ones. If entries are stored off-heap then both a key and value of an entry are unswapped, Unswapped values are not used by backup filters thus we have to omit unswapping of the values at all. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
