Nick Aldwin created BEAM-8513: --------------------------------- Summary: RabbitMqIO: Allow reads from exchange-bound queue without declaring the exchange Key: BEAM-8513 URL: https://issues.apache.org/jira/browse/BEAM-8513 Project: Beam Issue Type: Improvement Components: io-java-rabbitmq Environment: testing with DirectRunner Reporter: Nick Aldwin
The RabbitMqIO always declares an exchange if it is configured to read from it. This is problematic with pre-existing exchanges (a relatively common pattern), as there's no provided configuration for the exchange beyond exchange type. (We stumbled on this because RabbitMqIO always declares a non-durable exchange, which fails if the exchange already exists as a durable exchange) A solution to this would be to allow RabbitMqIO to read from an exchange without declaring it. This pattern is already available for queues via the `queueDeclare` flag. I propose an `exchangeDeclare` flag which preserves existing behavior except for skipping the call to `exchangeDeclare` before binding the queue to the exchange. -- This message was sent by Atlassian Jira (v8.3.4#803005)
