Using Locks for Concurrent Updates

NCache provides a clustered environment where multiple clients can access cache data. In such a situation, parallel requests may occur for same data changes e.g. multiple parallel threads from within multiple applications can issue an update call against the same data.

If you want to make sure that no application or thread performs functions on any data set simultaneously, NCache provides two different locking techniques to cater situations like that.
