Gus Heck commented on SOLR-11722:
---------------------------------
Sorry it's been so long to update here, life got "interesting". I see your
point with respect to replica allocation. We can make the template collection
something added later if folks seem to want it. I've gone partway into
implementing, the timezone thing is somewhat complicated by the truncation of
the milliseconds in the pattern for the collection name, which probably
requires that the formatter doing the truncation to have a matching timezone
(timezones are political entities, not necessarily bound by sensibilities or
mathematical convenience, so I'm not confident about assuming that none of them
ever messed with (or will mess with) milliseconds....)
I'm looking into the way the router property works, I think we can do something
similar, though I'm not sure that the code for that is directly reusable. I'm
working on a patch which will hopefully be presentable soon.
> API to create a Time Routed Alias and first collection
> ------------------------------------------------------

> Key: SOLR-11722
> URL: https://issues.apache.org/jira/browse/SOLR-11722
> Project: Solr
> Issue Type: Sub-task
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Reporter: David Smiley
>
> This issue is about creating a single API command to create a "Time Routed
> Alias" along with its first collection. Need to decide what endpoint URL it
> is and parameters.
> Perhaps in v2 it'd be {{/api/collections?command=create-routed-alias}} or
> alternatively piggy-back off of command=create-alias but we add more options,
> perhaps with a prefix like "router"?
> Inputs:
> * alias name
> * misc collection creation metadata (e.g. config, numShards, ...) perhaps in
> this context with a prefix like "collection."
> * metadata for TimeRoutedAliasUpdateProcessor, currently: router.field
> * date specifier for first collection; can include "date math".
> We'll certainly add more options as future features unfold.
> I believe the collection needs to be created first (referring to the alias
> name via a core property), and then the alias pointing to it which demands
> collections exist first. When figuring the collection name, you'll need to
> reference the format in TimeRoutedAliasUpdateProcessor.
