             Summary: SQL: Enable lazy mode by default
                 Key: IGNITE-11341
                 URL: https://issues.apache.org/jira/browse/IGNITE-11341
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov
            Assignee: Taras Ledkov


We redesigned lazy mode, so that now it doesn't spawn new thread and has the same performance
as old "eager" mode (IGNITE-9171). However, we didn't enable it by default because H2 1.4.197
contains several bugs causing query engine slowdown in some cases when lazy mode is set. These
issues are resolved in H2 master and will become available as a part of the next release (presumably
1.4.198). 

We need to make lazy mode enabled by default once new version is available (IGNITE-10801).
