David Smiley commented on SOLR-11166:
-------------------------------------
[~janhoy] if you wish to espouse the benefits of collection based time
sharding, I think that issue is SOLR-9562. Please copy your comments there;
I'd like to consider the merits of this further; maybe re-open the issue.
> Create a new router to automate time-based sharding

> Key: SOLR-11166
> URL: https://issues.apache.org/jira/browse/SOLR-11166
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Reporter: Shawn Heisey
>
> 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.
