Old (In previous patchset too):

• Remove ndb_use_exact_count giving up to 300% performance improvements on Joins in NDB
• INFORMATION_SCHEMA table for NDB node status
• NDB Cluster Log as CSV file (suitable for ENGINE=CSV)
• Skeleton Engine (build from storage/skeleton)
• MyHTTP Engine (build from storage/myhttp)
• PBXT Engine (build from storage/pbxt)

Availability:

• Patch (apply with -p1 to mysql 5.1.22) 4.0 MB
  • Applies cleanly on a BK source tree… a few files don’t exist in the tarball on dev.mysql.com (due to the way it’s built)… so when asked for “file to patch” just hit enter and then choose y to skip that patch.
• README (list of patches, descriptions) 13kb
• quilt patch series tarball (individual patches) 4.1MB
• diffstat 228k

Feedback much appreciated.
