Five weeks after our XAP 12.0 release, we’re happy to announce the general availability of GigaSpaces XAP 12.0.1 for download and upgrade!

XAP 12.0.1 builds on top of our XAP Open Source In-Memory Data Grid with great new features, tons of improvements and bug fixes. All GigaSpaces XAP customers are encouraged to upgrade soon.

XAP 12.0.1 New Features and Enhancements

Space Query Plan

The Space SQL Query Plan provides XAP developers with the capability to inspect the query execution plan, how many entries were scanned, and which indexes were used. This is especially helpful during space class modeling to make sure you have the right data model and query filters (read more).

MemoryXtend Windows Support

We’ve enhancement our multi-tiered data storage feature to support Windows environments.  XAP users are now quickly able to try out storage tiering and fast data reload features on Windows.

WebUI and Service Grid Enhancements

We’ve improved WebUI monitoring by enriching it with more information logging information for troubleshooting such as: generating hosts-dump files, service discovery information and a few others.
