Subject Re: idempotentConsumer is not idempotent?
Date Fri, 07 Jun 2013 06:01:45 GMT
How in practice do (or do they?) people use idempotentConsumer when creating
"idempotent" web service interfaces?

Do they use idempotentConsumer only with one-way operations, do they have
have idempotentConsumer + some kind of hand made reply message caching with
request-response operations, or....?

Because I can't see how idempotentConsumer can be used if you have
request-response type of services, such as
updateThisAndThatAndShowResults(). In case of response message getting lost,
client would retry calling the idempotent service (which it can do as many
times as it wants) but would not get the response message.
