Subject [jira] [Commented] (SOLR-2592) Pluggable shard lookup mechanism for SolrCloud
Date Mon, 17 Sep 2012 20:55:08 GMT


Michael Garski commented on SOLR-2592:

The latest patch I submitted (SOLR-2592_r1384367.patch) still requires encoding the value
to be hashed within the unique id such as with a composite id. I am more in the mindset of
keeping it simple by encoding the hashed value into the document's unique id, and will defer
to the committers provide guidance in the approach taken.  At the end of the day, either solution
will address my need of ensuring related documents are all on the same shard and I can query
a given subset of shards rather than the entire collection.  

I was not aware of SOLR-3133, however it looks to be a duplicate of SOLR-2656 which was committed
on March 27, 2012, giving the realtime get handler distributed support.

> If the data in a cloud can be partitioned on some criteria (say range, hash, attribute
value etc) It will be easy to narrow down the search to a smaller subset of shards and in
effect can achieve more efficient search.
