Infinispan 6.0

How does Infinispan support explicit eager locking?

Infinispan cache interface exposes lock API that allows cache users to explicitly lock set of cache keys eagerly during a transaction. Lock call attempts to lock specified cache keys across all cluster nodes and it either succeeds or fails. All locks are released during commit or rollback phase.

Consider a transaction running on one of the cache nodes:

   cache.lock(K)    // acquire cluster wide lock on K
   cache.put(K,V5)  // guaranteed to succeed 
   tx.commit()      // releases locks
