Subject [jira] [Commented] (IGNITE-4540) Ability to disable default H2 Indexing.
Date Wed, 11 Jan 2017 22:40:16 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-4540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15819413#comment-15819413

Valentin Kulichenko commented on IGNITE-4540:

[~amashenkov], I don't think we need to add any new options for this. Current problem is that
we go though two different checks before calling {{IndexingSpi.store(..)}}: {{GridCacheQueryManager.enabled()}}
and then {{GridIndexingManager.enabled()}}. When custom {{IndexingSpi}} is used, the second
one is true, but the first one is false. We need to fix the logic and make sure everything
is working properly in this case.

>             Project: Ignite
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.8
>            Reporter: Andrew Mashenkov
>            Priority: Minor
>             Fix For: 1.9
> It is impossible for now to use IndexingSPI without H2Indexing due to next reasons:
> - H2Indexing always starts if IgniteH2Indexing class found in classpath.
> - if IndexingTypes are set and IndexingSPI is configured, then both IndexingSPI and H2Indexing
is used. If IndexingTypes is not set, then both indexers are disabled.
> We need to add an option that force disabling H2IndexingSpi. 
> It look like the only workaround for now is remove ignite-indexing jar from classpath.
