getscattercastendpoints reports the set of scattercast endpoints known to all currently running cluster members.

This command may be issued at any time. If cluster membership changes during the read command, this causes an immediate failure, reporting that the cluster membership changed. This is for consistency with write commands.

Command

 
getscattercastendpoints
  Description
    Get the scattercast endpoints for the cluster.

Examples

Single node read with consistent endpoints:

[Rhino@localhost (#1)] getscattercastendpoints
[Consensus] Disk Mapping   : Coherent
[Consensus] Memory Mapping :
      [101] Address  : 192.168.0.127:12000
      [102] Address  : 192.168.0.127:12001

Two nodes read, where node 102 has different in-memory and disk mappings:

[Rhino@localhost (#2)] getscattercastendpoints
[101] Disk Mapping   : Coherent
[101] Memory Mapping :
      [101] Address  : 192.168.0.127:12000
      [102] Address  : 192.168.0.127:12001

[102] Disk Mapping   :
      [101] Address  : 192.168.0.127:12000
      [102] Address  : 192.168.0.127:12001
      [103] Address  : 192.168.0.127:18000

[102] Memory Mapping :
      [101] Address  : 192.168.0.127:12000
      [102] Address  : 192.168.0.127:12001

Read failed due to a cluster-membership change:

[Rhino@localhost (#3)] getscattercastendpoints
[Consensus] Disk Mapping   : Cluster membership change detected, command aborting
[Consensus] Memory Mapping : Cluster membership change detected, command aborting
