Denis Magda created IGNITE-3869:
-----------------------------------

             Summary: Reduce number of temporal objects produced by H2
                 Key: IGNITE-3869
                 URL: https://issues.apache.org/jira/browse/IGNITE-3869
             Project: Ignite
          Issue Type: Task
          Components: cache
    Affects Versions: 1.4
            Reporter: Denis Magda
            Assignee: Sergi Vladykin
             Fix For: 2.1


Presently during the execution of a query H2 generates huge number of temporal objects (kind of wrappers) that eventually exhaust the heap and trigger long GC pauses. 

Need to revisit present implementation improving Ignite SQL engine and/or H2.
