-----------------------------------
Summary: 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.
