New SENDAs of Swarm 11.2, SCSP SEND has been expanded to support all feed types and to use the new replication (PUSH) method. For backwards compatibility, the following legacy behavior of SEND is still supported. If a SEND request is missing the new required query arguments, then the behavior described here is in force. (v11.2) |
The SCSP SEND method applies to both named and unnamed objects. The SEND request allows explicit transmission of a single object from a source cluster to a remote one, such as for keeping two clusters immediately synchronized. This feature is best used with a replication feed, which will act as a catch-up mechanism if the intracluster network is down or the SEND command should fail.

Responses to SEND
