Apache Storm integrates with many queueing and database systems. Apache Storm's spout abstraction makes it easy to integrate a new queuing system.

Out of the box, Apache Storm ships with integrations for:

• Apache Kafka (via storm-kafka-client)
• HDFS (via storm-hdfs)
• JDBC databases (via storm-jdbc)
• JMS (via storm-jms)
• Redis (via storm-redis)

Integrating Apache Storm with other systems is straightforward. Simply open a connection to your database or service and read/write like you normally would. Apache Storm will handle the parallelization, partitioning, and retrying on failures when necessary.
