The ordering key section of aerospike-pubsub-outbound.yml

The ordering-key section of the /etc/aerospike-pubsub-outbound/aerospike-pubsub-outbound.yml controls how Aerospike records are ordered to the destination.

Here is a list of the ordering key modes:

• static Always order the records by a fixed value.
• namespace Uses the namespace of each Aerospike record as the ordering key.
• set Uses the set of each Aerospike record as the ordering key.
• bin Uses the value of a bin in each Aerospike record as the ordering key.
• digest Uses the digest of the Aerospike record as the ordering key.

note

• If an ordering key for a record is missing, then the record is dispatched without an ordering key.
• If an ordering key for a record is specified then a regional-endpoint should be specified for the record. Ordering works only when published to a regional endpoint service.
