/**
 * 

You can use the following system properties to configure the Near Cache invalidation:

hazelcast.map.invalidation.batch.enabled: Enable or disable batching. Its default value is true. When it is set to false, all invalidations are sent immediately.

hazelcast.map.invalidation.batch.size: Maximum number of invalidations in a batch. Its default value is 100.

hazelcast.map.invalidation.batchfrequency.seconds: If the collected invalidations do not reach the configured batch size, a background process sends them periodically. Its default value is 10 seconds.

If there are a lot of clients or many mutating operations, batching should remain enabled and the batch size should be configured with the hazelcast.map.invalidation.batch.size system property to a suitable value.
