in this area of the code I implement checks for the following:
name
start
router.field
router.name
router.interval
router.max-future-ms
TZ
collection-create.config
Only that last one could possibly be left to the collection-create
infrastructure. The rest are ours (note that the router ones are not the
collection level routing but the alias level routing).
> 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
> Attachments: SOLR-11722.patch, SOLR-11722.patch

>
> 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.
