Does Qpid support persistence (durability)?
Yes, there are third-party (non-Apache) modules for both C++ and Java. Historically, BDB has been used to provide persistence for both C++ and Java. However, this has created a licensing conflict with Apache, and thus the store modules are maintained off-site. The Java broker includes a fully Apache licensed persistent store that uses Derby DB. The terms durable and persistent are used interchangeably in this FAQ.
