Qpid's programming documentation( http://qpid.apache.org/books/0.8/Programming-In-Apache-Qpid/pdf/Programming-In-Apache-Qpid.pdf) says:
reliability one of: > unreliable, at-least-once, atmost-once, exactly-once Reliability indicates the level of reliability that the sender or receiver. unreliable and at-most-once are currently treated as synonyms, and allow messages to be lost if a broker crashes or the connection to a broker is lost. at-least-once guarantees that a message is not lost, but duplicates may be received. exactly-once guarantees that a message is not lost, and is delivered precisely once. Currently only unreliable and at-leastonce are supported. Does this means, even if I install the store module, I would not be able to send a reliable message (as in exactly once). Daryoush
