Help

1

i have two zones with 3 nodes in each zone that is one Master Aggregator( MA ) and two leaves in Zone 1 and Child Aggregator and two leaf nodes in Zone 2.

nodes: MA_ctl01, leaf01, leaf03 > zone1
CA_ctl02,leaf02,leaf04 > zone2

I want Child aggregator in Zone 2 to promote itself in case of Zone 1 goes down. is this feature available in Single Store DB version 8.0.6 and if not how can we achieve this otherwise.

You are on pretty old versions of SingleStore

8.0 is almost EOL

Automatic failover will not happen even in 8.5

What all you need to do is to run promote aggregator as master if the old master is not damaged permanently.
