Hi Dan,
I am not using any transactions that span across multiple caches.
Thanks,
Faseela

Subject: Re: [infinispan-dev] Doubt Regarding Infinispan Cache Creation limit
There is some extra cost if you have transactions that span multiple caches: each cache is
registered as a separate XA resource with the Transaction Manager. With a single cache,
there would be a single prepare/commit RPC, regardless of how many keys the transaction
modified. With multiple caches, there are as many prepare and commit RPCs as there are
caches touched by the transaction.

Hi Fassela,
In future please post these kind of questions on the infinsipan forum so that other can
benefit from them as well ;)

Hello,
Is there any limitation on the number of infinispan caches that can be created, in a
clustered environment?
I know users that created thousands, I'm not aware of an upper bound but creating a
cache certainly brings it cost.
Also, is there any performance difference between the below two cases :
Case 1 : Constructing a cache with 10000 entries
Case 2 : Splitting the above cache into 100 caches of 100 entries.
Entry count is same in both the cases, but will there be any significant performance
overhead in creating 100 caches?
creating the cache has it's cost, but once it is created, the performance should be
pretty much the same.
Thanks,
Faseela
