Replica Enumeration

Aerospike
Defines algorithm used to determine the target node for a command. Scan and query are not affected by replica algorithm.

Syntax

Members

  Member nameValueDescription
MASTER0 Use node containing key's master partition.
MASTER_PROLES1 Distribute reads across nodes containing key's master and replicated partitions in round-robin fashion. Writes always use node containing key's master partition.
SEQUENCE2 Try node containing master partition first. If connection fails, all commands try nodes containing replicated partitions. If socketTimeout is reached, reads also try nodes containing replicated partitions, but writes remain on master node.
PREFER_RACK3 Try node on the same rack as the client first. If there are no nodes on the same rack, use SEQUENCE instead.

rackAware, rackId and server rack configuration must also be set to enable this functionality.

RANDOM4 Distribute reads across all nodes in cluster in round-robin fashion. Writes always use node containing key's master partition.

This option is useful when the replication factor equals the number of nodes in the cluster and the overhead of requesting proles is not desired.
