Taras Ledkov commented on IGNITE-10580: --------------------------------------- [~vozerov] The H2 connection leak is fixed. Unfortunately we have to add two collections of {{Connection}} to track opened connections. It may be cause of a little performance drop. May be it makes sense to run the benchmarks. Also the new class {{AbstractIndexingCommonTest}} is used as the base class for the most tests in the *indexing* module to check all H2 connection are closed at the end of the test. > H2 connection and statements are reused invalid for local sql queries > --------------------------------------------------------------------- > > Key: IGNITE-10580 > URL: https://issues.apache.org/jira/browse/IGNITE-10580 > Project: Ignite > Issue Type: Bug > Components: sql > Affects Versions: 2.7 > Reporter: Taras Ledkov > Assignee: Taras Ledkov > Priority: Major > Fix For: 2.8 > > > The threadlocal connection & statement cache is used invalid for local > queries. > Steps to reproduce: > # Open iterator for local query {{Query0}}; > # In the same thread open one more iterator for {{Query1}} (SQl statement > must be equals to {{Query0}} and doesn't contains query parameters); > # Fetch from the first iterator. > The exception {{The object is already closed [90007-197]}} will be thrown. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
