Description

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.
