Subject [jira] [Commented] (SOLR-9690) Date/Time DocRouter
Date Mon, 14 Aug 2017 23:33:01 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16126617#comment-16126617

Michael Sun commented on SOLR-9690:
-----------------------------------

It's a great idea Solr to be time-series aware. I also see design details in SOLR-11166  by
[~elyograg].

One concern is load balancing. In some use cases the amount of docs indexed per day (or per
week etc.) highly fluctuates and can't be predicted in advance. Using sharding approach, the
time range for each shard seems decided when the shard is created, which is before Solr index
any data for that shard. If it turns out the data volume for that shard is too high later,
the only choice is shard splitting, which can be expensive.

> This issue is for a custom Solr DocRouter that works with dates/times (or perhaps any
field providing an int).
