Subject Re: example using HazelcastIdempotentRepository in Spring DSL
Date Wed, 13 Mar 2013 18:19:57 GMT
I have a few more questions regarding Hazelcast as an idempotent repository.
FWIW, I haven't used Hazelcast before. 

I have a requirement to prevent duplicate messages from being published to a
JMS endpoint. The messages are aggregated and a composite "primary value" is
formed. The message volume is large: 10 - 100 million day. The primary value
uses the current date as part of the value; therefore the idempotent
repository only needs to contain a day's worth of primary values. 

Is it possible to configure the open source version of Hazelcast to spill
values to disk after a pre-determined size or is this only available in the
Enterprise edition? I have 4 gig allocated to my web container but it runs
out of memory after 8 hours or so...
