Hazelcast Platform: Expanded Vision

8. © 2015 Hazelcast Inc. Confidential & Proprietary 8
Features Description
Client Protocol New Hazelcast Client Protocol
Client Cross Version
Compatibility
Ability to upgrade clients independently from servers and other clients.
New Features for JCache Adds Partition Lost Listener, Quorums, Split brain handler as in IMap to JCache.
Spring Transaction API
Integration
For easier transaction management for applications which use Hazelcast as their memory
store.
Quartz Integration An extension to store Quartz tasks in Hazelcast.
Improved Hazelcast
Hibernate Caching
Provides a new Hibernate region cache that supports soft locking.
ReplicatedMap
Improvements
Enhancements to ReplicatedMap
Docker Integration Ability to start Hazelcast instances on Docker environments easily.
Cascading Integration Computation Fabric for Cascading 3.
New Hazelcast 3.6 Open Source Features

9. © 2015 Hazelcast Inc. Confidential & Proprietary 9
Features Description
Discovery SPI Provide an extension SPI to attach external cloud discovery mechanisms. Finds other
Hazelcast instances based on certain filters and provides their corresponding IP addresses.
Refresh-Ahead Caching Keep subset of entries up-to-date with the database so that expired entries don't have to be
re-fetched i order to accelerate access.
Lite Members Ability to denote certain members in the cluster do not store data (partitions). These would
then be used for compute.
Staged Latency Monitoring Provides per-Operation fine-grained information about processing time at every stage of
operations processing in order to identify bottlenecks in operation processing.
Paging Predicate Seek Allow constant time access to a specific page in a Paging Predicate. Provides a new method
setPage(int PageNumber) that sets the Page.
Try Lock with Lease Ability to try to acquire lock with a lease time.
Rule Based Query Optimizer Make queries significantly faster by using static transformations of queries.
Type Constraints SQL performance improved by being able to specify type constraints.
Index Memory Consumption
Improvements
* Reduces index memory consumption to be no more than a small ten's of bytes per item.
