Teiid 7.6 Beta1

7.6 Beta1 is now available.  It contains an overhaul of the memory management system, which includes: 
  • A Fixed Memory Buffer - A serialization buffer will be allocated to increase disk through-put.  It is also managed as a second tier cache.  You may optionally configure the size and set it to use off-heap memory - which is especially useful for dealing with larger amounts (typically 32BG+) of memory from the VM.  The memory buffer also allows for better disk usage based upon fixed allocation blocks vs. the old Teiid scheme which used a file per table/tuple buffer.
  • Concurrent LRFU - the main eviction algorithm was further refined to be concurrent and to better handle table work loads.
  • Numerous Performance Improvements - batch size estimation, serialization, and value type resolution were all improved.
You may also now configure query timeout defaults at both the server and per-VDB level.

Now is a great time to provide feedback on any issues or minor enhancements before it's too late for the release.
