Remarks

If there is already an entry associated with the specified key in this region, the entry's previous value is overwritten. The new put value is propogated to the java server to which it is connected with. Put is intended for very simple caching situations. In general it is better to create a ICacheLoader object and allow the cache to manage the creation and loading of objects. For local region instance - Puts a new value into an entry in this region in the local cache only. For distributed region instance - Puts a new value into an entry in this region and this operation is propogated to the Gemfire cache server to which it is connected with.

Updates the [!:CacheStatistics.LastAccessedTime] and [!:CacheStatistics.LastModifiedTime] for this region and the entry.

If remote server put fails throwing back a CacheServerException or security exception, then local put is tried to rollback. However, if the entry has overflowed/evicted/expired then the rollback is aborted since it may be due to a more recent notification or update by another thread.
