----------------------------------------
Summary: SQL: implement collecting query metrics from map step to
reduce step
Key: IGNITE-3768
URL: https://issues.apache.org/jira/browse/IGNITE-3768
Project: Ignite
Issue Type: Task
Components: SQL
Affects Versions: 1.6
Reporter: Alexey Kuznetsov
Fix For: 1.8
Ignite SQL engine use a mapreduce to execute query on cluster.
Some node map queries over cluster and after they are completed and reduced on
initial node.
In current implementation we measure duration on initial node and on all nodes
where two-step queries are executed, but only overall duration is returned.
We also need to return duration from all two-step queries.
