[jira] [Created] (IGNITE-10304) SQL: Encapsulate H2 query execution
into ConnectionManager
Vladimir Ozerov created IGNITE-10304:
----------------------------------------
Summary: SQL: Encapsulate H2 query execution into ConnectionManager
Key: IGNITE-10304
URL: https://issues.apache.org/jira/browse/IGNITE-10304
Project: Ignite
Issue Type: Task
Components: sql
Reporter: Vladimir Ozerov
Fix For: 2.8
This ticket should be done after IGNITE-10299. Currently {{ConnectionManager}} exposes cached H2 connections to the outside. Sometimes these connections are used in safe manner and {{ConnectionManager.onSqlException}} is called to recycle bad connection. But most of the time this is not the case, what may lead to unexpected behavior.
Let's try to hide all statement execution logic inside {{ConnectionManager}} to avoid this.
