Package com.apple.foundationdb.system

Class SystemKeyspace

java.lang.Object

com.apple.foundationdb.system.SystemKeyspace

@API(INTERNAL)
public class SystemKeyspace
extends Object

Keys living in the FDB system and special keyspace. These keys are used to communicate system configuration information and related information between the FoundationDB server and client. This API is API.Status.INTERNAL and should not be consumed directly by adopters. They should instead generally be referenced through wrapper functions that exist in this project and in the Record Layer core project.

There is currently a project to provide a framework for FoundationDB clients to make use of the special key space API. As that project develops, this class may become unnecessary. See: Special-Key-Space.
