Active - Passive Fuse FTP interfaces using Idempotent repository

Question

We have a clustered environment where same camel ftp endpoint is installed on multiple fuse instances. I want message(file) to be consumed by only one fuse instance. I am planning to achieve this by implementing IdempotentRepository interface with database persistence. Want to make sure that this approach will work or there is a better way to do it?

Answer 1

If you don't want to depend on a database for doing this you could try with Hazelcast. Hazelcast is a distributed data cache that can be used as a idempotent repository without external dependencies. Also, Apache Camel provides a class for doing this. There is a nice tutorial explaining how to do it: Hazelcast Idempotent Repository Tutorial
