MultiCore and SpellChecker replication
--------------------------------------
Key: SOLR-433
URL: https://issues.apache.org/jira/browse/SOLR-433
Project: Solr
Issue Type: Improvement
Components: replication, spellchecker
Affects Versions: 1.3
Reporter: Otis Gospodnetic
Fix For: 1.3
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 -

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
