----------------------------------------
Summary: Implement IgniteReadWriteLock data structure
Key: IGNITE-637
URL: https://issues.apache.org/jira/browse/IGNITE-637
Project: Ignite
Issue Type: Bug
Components: data structures
Reporter: Dmitriy Setrakyan
We need to add {{IgniteReentrantReadWriteLock}} data structure in addition to
other data structures provided by Ignite. {{IgniteReentrantReadWriteLock}}
should have similar API to
{{java.util.concurrent.locks.ReentrantReadWriteLock}} class in JDK.
As an example, you can see how
[IgniteCountDownLatch|https://github.com/apache/incubator-ignite/blob/master/modules/core/src/main/java/org/apache/ignite/IgniteCountDownLatch.java]
is implemented in
[GridCacheCountDownLatchImpl|https://github.com/apache/incubator-ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/datastructures/GridCacheCountDownLatchImpl.java]
class.
In general we need to have an entity in ATOMIC cache storing number of readers
and writers and allow user threads to block whenever needed to wait for a lock.
