Access to many region from one client cache
Hello All,
In one of our development, the cache contains several regions and
subregions-One of our services accesses to the regions and the subregions
through a classical ClientCache.getRegion( Path). Once we get the region
with the key, we get the value.
The service parameters contain the region path and the key of the value we
want to retrieve. So, for each service invocation, we plan access to the
region through the method ClientCache.getRegion( Path) then get the value
with the key Region.get (Key).
Our question:
Is the method ClientCache.getRegion( Path) efficient enough to advise me to
invoke ClientCache.getRegion( Path) for each invocation?
If not, is it is better to store the regions, in a lazy way, in a Map(<
path>, < region>), and avoid a new connection to a region for each
invocation.
I have no idea how the process to get the region works in the deep.
Thank you for your help
Best regards

Hello Bruce
OK, thank you for this information. So I will directly access to the region through the mapping in the client cache.
I forget the map idea.
Thank you all (and Antony too)

Hi Paul,
The client cache maintains a mapping from Region path to a Region implementation. The getRegion(String) method goes through a few checks, so it’s not free, but it doesn’t involve any interaction with other processes.

It’s hard to make blanket recommendations without understanding your workload. Depending on your latency budget you may care more about simplicity vs speed tradeoffs. The most important thing is to measure and then focus your optimizations on code areas that have a demonstrated impact on your SLA.
