Ryan McKinley commented on SOLR-350:
------------------------------------
> If we were to use the 'alias' to map behaviors,
how would an alias map different behaviors? Alias just offer multiple ways to
access the *same* core and the same behavior. RequestHandlers don't know what
path requested them.
My point about mod_rewrite was referring to the use case you referred to:
making the log files easier to parse per user.
Re production and stage, why do you need aliasing for that? each core has name
- when 'stage' is ready -- it can swap with 'production'
> 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
>
so if you serialize at the beginning, you have:
<core name="core,0" alias="main" ... />
at the end you have:
<core name="core,1" alias="main" ... />
if you run that every hour, do you end up with "core,1000" or switch between
them? This would require you ask MultiCore, what i the 'id' for the core
sitting at 'main' before you can operate on it. Why add this complexity?

> In SOLR-215, we enabled support for more then one SolrCore - but there is no

> We need to make some interface to manage, register, modify avaliable SolrCores
