This document summarizes Joel Bernstein's presentation on parallel SQL in Solr. The key points are: 1. SQL provides an easier way for users to query Solr compared to its other complex APIs, and SQL queries can be optimized. 2. Solr 6.0 introduces a SQL interface that supports high-cardinality aggregations, distributed joins, and Solr search predicates. 3. Under the hood, SQL queries are compiled into TupleStreams and executed in parallel across worker collections using a streaming API and expressions. This allows massive throughput for queries.
