Hoss Man commented on SOLR-433:
-------------------------------
as i recall, most of the scripts currently take a "-d data_dir" option ... and
then use makethe following assumptions...
1) ${data_dir}/index is what gets snapshooted/snapinstalled
2) ${data_dir}/snapshot* is the pattern for naming snapshots.
a good way to evolve the scripts would probably be to have an alternate set of
options ... maybe "-D dir" and "-S snapshots" that assumes ${dir} is where
*all* the data to be snapshooted/snapinstalled lives, and ${snapshots} is where
*all* snapshoots live.
(except i think some of the scripts already have a -D .. snappuller or
snapcleaner maybe?)
alternate idea: we don't have to add a command line option at all ... support
for something like this could require special scripts.conf options.
> 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 -
> 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
