WebSphere® eXtreme Scale Version 8.6 has many new features including:
- With the new enterprise data grid, Java and .NET applications can now interact natively with the same data in the same data grid.
- A new REST Gateway provides simple access from other programming languages using HTTP.
- WebSphere eXtreme Scale V8.6 delivers a faster, more compact serialization format called eXtreme Data Format (XDF), which is neutral to programming languages.
- A new transport mechanism, eXtreme IO (XIO) removes the dependency on the IBM ORB, enabling easier integration with existing environments.
- By installing the WebSphere eXtreme Scale Client for .NET, you can deploy .NET applications that access the data grid.
- When you develop client applications that interact with the data grid, you might require queries that retrieve automatic, real-time results when new entries are inserted or updated. You can use the new continuous query function to be notified in your client Java™ virtual machine (JVM) when data is inserted or updated in the data grid. This feature makes data grid and data management easier for both developers and administrators.
- Global index extends the built-in HashIndex plug-in, and it runs on shards in a distributed, partitioned data grid. Global index tracks the location of indexed attributes in the data grid and provides efficient ways to find partitions, keys, values, or entries using attributes in large, partitioned data grid environments. This feature is also integrated into the default dynamic cache function to provide higher performance.
- Inverse Range index extends the built-in mapIndex plug-in and provides an efficient way to store and retrieve values for the keys that are within an established range; for example, a "sales promotion" or an "insurance policy" based on a range of dates or some other criteria.
- Catalog and container servers can use High Performance Extensible Logging (HPEL) as an alternative to the basic log and trace facility.
- The message center provides an aggregated view of event notifications for log and first-failure data capture (FFDC) messages for all servers in an eXtreme Scale domain. You can view these event notifications with the message center in the web console, the xscmd utility, or programmatically with MBeans.
- The near cache invalidation function can be enabled to remove stale data from the near cache. When an update, deletion, or invalidation operation is run against the remote data grid, an asynchronous invalidation gets triggered in the near cache. This feature is integrated into the dynamic cache function as a configuration option to provide higher performance.
- Use the new Multi-Partition Transaction support to read and write multiple partitions to provide a two-phase commit protocol to guarantee atomic updates.
- Disk Overflow Support extends the capacity of the data grid by writing infrequently used data to disk.
- Additional API Enhancements including upsert(), lock(), and OutputFormat, are now available.
- General Configuration Enhancements, such as the nearCacheEnabled flag and Eclipse XML editor content assist support.
