This variable was used in MySQL 4.0 to turn on some 4.1 behaviors, and is retained for backward compatibility. Its value is always OFF .

This feature is experimental only, and not supported in production . For additional information, see User-defined partitioning and the NDB storage engine (NDB Cluster).
