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"?
- 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.
