If my understanding is correct, let me try to explain how I have done for my use case.
Let's say you have position1 and position2 regions on server. - Client is accessing data from position1. - On end of day you receive a trigger and data will be loaded in position2 region. - Meanwhile data load is running, client is still accessing data from position1. Now as soon as data load on position2 is completed you publish a 'DataLoadCompleted' event into new /event region with attribute as current=position2. Let your client register cqlistsner and on this match event you switch to position2 region in cqlistsner handler. I am assuming that in your client you already have reference to both client proxy region or gemfire template. Example: GemfireTemplate position1Template GemfireTemplate position2Template GemfireTemplate currentTemplate On cqlistsner event you switch current template to position1 or position2 depending on "current" property explained above.
