<div dir="ltr">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.<br>

</div>I know users that created thousands, I'm not aware of an upper bound but creating a cache certainly brings it cost.<br>

</div>creating the cache has it's cost, but once it is created, the performance should be pretty much the same.<br>
