Joel Bernstein commented on SOLR-7560:
--------------------------------------
I will spend some time working on the documentation. So far the docs mostly
covers how to form queries.
The link to docs is here:
https://cwiki.apache.org/confluence/display/solr/Parallel+SQL+Interface
I'll post back to this ticket when I've added the sections on sending the
query, configuration and the architecture.
If you want to get a jump on things the sample configs in trunk have the
request handlers already setup. You can take a look at the test cases to see
how to send a SQL query:

> This ticket provides support for executing *Parallel SQL* queries across
> SolrCloud collections. The SQL engine will be built on top of the Streaming
> API (SOLR-7082), which provides support for *parallel relational algebra* and
> *real-time map-reduce*.
> Basic design:
> 1) A new SQLHandler will be added to process SQL requests. The SQL statements
> will be compiled to live Streaming API objects for parallel execution across
> SolrCloud worker nodes.
> 2) SolrCloud collections will be abstracted as *Relational Tables*.
> 3) The Presto SQL parser will be used to parse the SQL statements.
> 4) A JDBC thin client will be added as a Solrj client.
> This ticket will focus on putting the framework in place and providing basic
> SELECT support and GROUP BY aggregate support.
> Future releases will build on this framework to provide additional SQL
> features.
