5.2. Disabling Return Values
As a default in Red Hat JBoss Data Grid, the
put() and remove() API operations return the original or previous values in the cache. However, if the original value was not required, this operation is wasteful.
To conserve the resources used, disable the return values. Note that this solution is only applicable for cache instances that only perform write operations (for example
put() and remove()). Implement this solution as follows:
Procedure 5.1. Disable Return Values
- Set the
IGNORE_RETURN_VALUESflag. This flag signals that the operation's return value is ignored. For example:cache.getAdvancedCache().withFlags(Flag.IGNORE_RETURN_VALUES)
- Set the
SKIP_CACHE_LOADflag. This flag does not load entries from any configured CacheStores. For example:cache.getAdvancedCache().withFlags(Flag.SKIP_CACHE_LOAD)
