Henri Biestro commented on SOLR-350:
------------------------------------
If we are making a new index - a new index version-, it can mean the schema and
the config can change; I may change my analysis chain or schema but also
warming queries, cache set up, etc. The config is thus not necessarily the same.
I may also want to have the new setup tested by a group of users before I make
it available to the whole population; http://host/productionl versus
http://host/stage. I might even have automated tests that verify that some
queries do return some expected documents.
If we were to use the 'alias' to map behaviors, it seems more convenient to
declare those within Solr than anywhere else; describing that
http://host/ryan/select queries on core main with an automated fq author='ryan'
should not force mod-rewrite usage imho.
Finally, the 'alias' command as it stands, allows to redefine an alias (without
havng to unalias first) so the sequence would be:
(considering <core name="core,0" alias="main" ... />)
LOAD core,1 // which could even be aliased as 'stage' at this time
send adds to core,1 // when done, could run verifications on 'stage'
ALIAS core,1 main // 'swap' so to speak, overwrites previous 'main' alias
UNLOAD core,0
