What is a central table?

A central table contains data which is universal to the network, but which is only stored internally on catalog servers and is never propagated out to edge servers.

The content of a central table is managed centrally from a catalog server.

Central tables are used to store particularly sensitive data such as customer address or financial information that must be retained in a highly-secure data centre or cloud environment.

You should only use a central table for data that specifically necessitate it as their use restricts the ability of the network to optimise its query strategies.
