> There has been some interest in time-based sharding on the mailing list. It is disappointing to have to inform users that if they want to implement this, they will be entirely responsible for all shard management.
> I think that creating new shards and directing new documents to the newest shard will be relatively easy parts of this router. There are some additional features that I think would be really useful:
> Automated merging of older shards into larger time periods.
> Some kind of aliasing to allow searching today, yesterday, this week, last week, this month, last month, and so on, with the list of searched shards changing when a new shard is created. I don't know if this would be part of the router or implemented elsewhere by another issue.
> The router should have a configuration option to indicate how frequently new shards should be created. Valid values should probably be hourly, daily, weekly, and monthly. Multiples of those time periods would be a very good idea. Another idea to consider: completely custom time periods.
