This page discusses how we can integrate Druid with other technologies.
Integrating with Open Source Streaming Technologies
Event streams can be stored in a distributed message bus such as Kafka and further processed via a distributed stream processor system such as Storm, Samza, or Spark Streaming. Data processed by the stream processor can feed into Druid using the Tranquility library.
Integrating with SQL-on-Hadoop Technologies
Druid should theoretically integrate well with SQL-on-Hadoop technologies such as Apache Drill, Spark SQL, Presto, Impala, and Hive.
