Does RabbitMQ support distributed (XA) transactions?

[Arshika Mohottige]

Hi Guys,

Can you outline the status of support for transactions in RabbitMQ, specifically distributed (XA) transactions?

Cheers,
Arshika

Transactions are supported in RabbitMQ, but they are not that much
used in the field. Acknowledgements and publish confirms are used
instead for reliability purposes [1].

There is no support for XA transactions. To reach or get near XA
transaction guarantees without the performance burden (or because it's
simply not supported), people use patterns like synchronization
(performing database commit right after the message acknowledgment,
aka "best-effort pattern"), retry for publishing, idempotent consumer.
