Which technology is used to implement a distributed shared memory data grid in a Mule cluster?

• A. Hazelcast
• B. Redis
• C. Memcached
• D. Apache Ignite

Answer: (A)

A distributed shared memory data grid in a Mule cluster relies on an in-memory data grid that lets multiple cluster nodes share data in memory with strong coordination and consistency. Hazelcast provides exactly that: an in-memory data grid that distributes maps, caches, queues, and other data structures across all cluster members, enabling fast, low-latency access and reliable replication. In Mule, Hazelcast is used to back distributed caches and shared state so that routing, session data, and other stateful information can be accessed consistently from any node in the cluster, improving availability and performance. While Redis, Memcached, or Apache Ignite offer in-memory capabilities, Hazelcast is the integration most commonly used in Mule for implementing the distributed shared memory data grid across a cluster.
