Detailed Description

LCStore implementation which stores data as a collection of CDB files.

Profiling indicates that on Linux, this implementation outperforms MySQL if the directory is on a local filesystem and there is ample kernel cache space. The performance advantage is greater when the DBA extension is available than it is with the PHP port.

See Cdb.php and https://cr.yp.to/cdb.html
