After finding the FireChief for a specific partition, Druid will need to find the specific queryRunner for each segment being queried by passing the query to FireChief. Currently Druid is passing the original query that contains all the segments need to be queried, it's possible that fireChief.getQueryRunner(query) returns more than 1 queryRunner because query.getIntervals() is not specific to a single segment. In this patch, for each segment being queried, Druid will update the query with its corresponding SpecificSegmentSpec. |

Druid
Druid is a distributed, column-oriented, real-time analytics data store that is commonly used to power exploratory dashboards in multi-tenant environments.
Druid excels as a data warehousing solution for fast aggregate queries on petabyte sized data sets. Druid supports a variety of flexible filters, exact calculations, approximate algorithms, and other useful calculations.
Druid can load both streaming and batch data and integrates with Samza, Kafka, Storm, and Hadoop.
