Package ctdb

A Clustered Database based on Samba's Trivial Database (TDB)


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.

Version: 4.20.2
