[jira] [Created] (SOLR-6473) Optimize the get-by-id path for search requests

Shalin Shekhar Mangar created SOLR-6473:
-------------------------------------------

             Summary: Optimize the get-by-id path for search requests
                 Key: SOLR-6473
                 URL: https://issues.apache.org/jira/browse/SOLR-6473
             Project: Solr
          Issue Type: Improvement
          Components: SolrCloud
            Reporter: Shalin Shekhar Mangar
             Fix For: 4.11


A search request which looks up a doc with just a uniqueKey can be optimised to lookup the right shard and send a distrib=false request and avoid the overhead of a distributed request.

The same can also be achieved by the /get handler but it has the (admittedly small) overhead of looking up from the transaction log as well.
