[jira] Commented: (SOLR-433) MultiCore and SpellChecker replication

["Jonathan Lee (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12620430#action_12620430 ] 

Jonathan Lee commented on SOLR-433:
-----------------------------------

I'm interested in getting using this patch to replicate the spell index, but I am not using multiple cores.  However, the scripts in the patch do not work for single core setups since the assume that ${core} contains a valid value.  Even specifying -c "" will not work, since the variable is used in paths.

> With MultiCore functionality coming along, it looks like we'll need to be able to:
>   A) snapshot each core's index directory, and
>   B) replicate any and all cores' complete data directories, not just their index directories.
> Pulled from the "spellchecker and multi-core index replication" thread - http://markmail.org/message/pj2rjzegifd6zm7m
> Otis:
> I think that makes sense - distribute everything for a given core, not just its index.  And the spellchecker could then also have its data dir (and only index/ underneath really) and be replicated in the same fashion.
> Right?
> Ryan:
> Yes, that was my thought.  If an arbitrary directory could be distributed, then you could have
>   /path/to/dist/index/...
>   /path/to/dist/spelling-index/...
>   /path/to/dist/foo
> and that would all get put into a snapshot.  This would also let you put multiple cores within a single distribution:
>   /path/to/dist/core0/index/...
>   /path/to/dist/core0/spelling-index/...
>   /path/to/dist/core0/foo
>   /path/to/dist/core1/index/...
>   /path/to/dist/core1/spelling-index/...
>   /path/to/dist/core1/foo
