Core "creation" and "reload"

[Prashant Golash <pr...@gmail.com>]

Hi,

I was just wondering between the two actions "creation" and "reload" of
core and have some doubts. Hope to clarify it.

a) *Reload core* - Happens when we explicitly "reloads the core". If
reloading fails (due to malformed config like elevate.xml etc), then solr
keep on serving request from old searcher (old core). Is this right?

b) *Creation of core* - This will happen when solr is restarted. Are there
any other ways by which we can trigger creation of already existing core
(for e.g by changing any file on solr like solrcore.properties or
solr.xml?). I have scenario where we push some files from git to solr
(rsync all files forcefully). While tailing logs, I found that sometimes
core creation is happening, but it does not happen every-time I push
configs, so I am confused why it is happening and not able to correctly
figure out the end-to-end flow.

Please let me know your thoughts?

Thanks,
Prashant
