-----------------------------------------
Summary: Sql. Avoid using blocking api in sql threads
Key: IGNITE-20887
URL: https://issues.apache.org/jira/browse/IGNITE-20887
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
As for now, there are two places which blocks sql thread in order to wait for
completion of the operation:
* {{join()}} on futures returned by {{UpdatableTable}} in {{ModifyNode}}
* finalisation of a transaction in {{QueryTransactionWrapper}}
Performance of a sql engine is sensitive to a blocking of sql threads because
every fragment of a query is bound to a particular thread.
Let's revise and fix aforementioned places.
