Partition Replicas

Types

There are three types of replicas.

• Master replica. A writable replica that contains all object information for the

partition. All partition operations (create, join, delete, and repair) occur from the

master replica of a given partition.

Only one master replica can be deﬁned for each partition.

• Read/write replica. Contains the same object information as the master replica.

Allows modifications (writes) to a partition, which are passed to other replicas of

the partition.

There can be any number of read/write replicas.

• Read-only replica. Contains the same object information as the master replica,

but the information can only be read. Used where reading of the partition is

required but writes to the partition should not occur.

NOTE: Log in requires a writable replica.

Also, bindery services requires a writable replica. When bindery services is set, use

either a master or read/write replica.

See chapter 4, “Understanding Bindery Services” for more information.
