Does camel support of any IdempotentRepository SPI that has async methods unlike https://github.com/apache/camel/blob/master/camel-core/src/main/java/org/apache/camel/spi/IdempotentRepository.java ?
I have implemented above interface on top of Couchbase API however I am using `Await` to block futures to send back add/remove/contains results and this is not currently provide the concurrency/performance we need on high load. -- --Behrad
