5.8.2. Distributed GET and PUT Operation Resource Usage

In distribution mode, the cache may execute a GET operation before executing the desired PUT operation.

This operation is very expensive in terms of resources. Despite operating in an synchronous manner, a remote GET operation does not wait for all responses, which would result in wasted resources. The GET process accepts the first valid response received, which allows its performance to be unrelated to cluster size.

Disable the Flag.SKIP_REMOTE_LOOKUP flag for a per-invocation setting if return values are not required for your implementation.

Such actions do not impair cache operations and the accurate functioning of all public methods, but do break the java.util.Map interface contract. The contract breaks because unreliable and inaccurate return values are provided to certain methods. As a result, ensure that these return values are not used for any important purpose on your configuration.
