Ryan McKinley updated SOLR-350:
-------------------------------
Attachment: SOLR-350-MultiCore.patch
Here is a quick sketch of what I think the multicore management/interface
should look like.
Essentially, it works like this:
A. If you do nothing, solr keeps working as it is - it has a little extra
checking at startup and each requests only makes an extra if( singlecore !=
null ) call
B. If you put a "multicore.xml" file in the startup instanceDir, a multicore
registry will be initialized. Each call to the SolrDispatchFilter will select
the core (from a synchronized map). Using the default core does not require a
synchronized map lookup.
In the attached patch, you select the core from the path:
http://host:port/context/handlerpath -- uses default core
http://host:port/context/@core0/handlerpath -- uses core0
http://host:port/context/@core1/handlerpath -- uses core1
This assumes handler names will not start with '@' (perhaps we should make it
a requirement that handler names don't start with any punctuation? this would
leave open special characters in the future?)
This still needs a servlet or request handler to manage core manipulation
(load, restart, etc). Since it handles functions across handlers, it should
probably be a servlet, but that makes it difficult to use the wt=json/xml stuff.
NOTE -- the core management stuff is untested, I'm attaching it now because I
don't have much time to work on it and hopefully someone else can carry on.
Parts of this patch clean up things from SOLR-215. Unless there is much
movement on this issue, I'd like to commit that part in a few days.
