clustered database to store temporary data


CTDB is a cluster implementation of the TDB database used by Samba and other projects to store temporary data. If an application is already using TDB for temporary data it is very easy to convert that application to be cluster aware and use CTDB instead.

CTDB provides the same types of functions as TDB but in a clustered fashion, providing a TDB-style database that spans multiple physical hosts in a cluster.

Features include:
 * CTDB provides a TDB that has consistent data and consistent locking across
   all nodes in a cluster.
 * CTDB is very fast.
 * In case of node failures, CTDB will automatically recover and repair all TDB
   databases that it manages.
 * CTDB is the core component that provides pCIFS ("parallel CIFS") with
 * CTDB provides HA features such as node monitoring, node failover, and IP
 * CTDB provides a reliable messaging transport to allow applications linked
   with CTDB to communicate to other instances of the application running on
   different nodes in the cluster.
 * CTDB has pluggable transport backends. Currently implemented backends are
   TCP and Infiniband.
 * CTDB supports a system of application specific management scripts, allowing
   applications that depend on network or filesystem resources to be managed in
   a highly available manner on a cluster.
