Hi,
This is the continuation of a conversation Tristan, Dan and myself started around adding
support for XA cache stores in Infinispan 6.0. It is also related to the CacheStore API
refactoring scheduled for 6.0 [1].
The problem:
When configuring an XA cache with a cache store it is possible for the cache store to end
up out of sync with in-memory data. In order to overcome that we would need cache store
enhancements.
Whilst this is definitely a limitation and a nice to have feature not sure that 6.0 is the
time and place to start this enhancement. Why?
There doesn't seem to be any explicit demand from the community/JDG for this feature
at the moment, so other features should take priority. There's also a potential
workaround for this: don't configure a cache store but the user to manage the XA write
in the store directly.
Wdyt?
I've also updated the documentation to clearly state that inconsistencies are
possible[2].
Cheers,
Mircea
