Rabbitmq

Rabbitmq source connector

Description

Used to read data from Rabbitmq.

Key features

• batch
• stream
• exactly-once
• column projection
• parallelism
• support user-defined split

tip

The source must be non-parallel (parallelism set to 1) in order to achieve exactly-once. This limitation is mainly due to RabbitMQ’s approach to dispatching messages from a single queue to multiple consumers.
