Group Replication distributed recovery is one of the key features and until now it was restricted to be executed over one mysql connection point automatically defined on mysql system variables port and host.
group_replication_recovery_endpoints we can specify through which interfaces can group replication recovery take place for a given member so that it controls where recovery traffic flows in the network infrastructure.
For each server we can configure a comma separated list of local endpoints and every endpoint contains information about the host and port.
An endpoint host can be specified with:
- IPV4 address
- IPV6 address inside square brackets
- a host name
that are bind to the MySQL server instance, but also allowed/included on bind_address.
And endpoint port must be a listening port on the MySQL server, that is, it must be one of report_port or admin_port system variables. Some of the endpoints connections may need more privileges. For example connections established to
An example of a network:
Assuming that on all servers MySQL system var
report_port is configured with
3306, until now we only could use network
10.0.0.0/8 to do recovery.
group_replication_recovery_endpoints we can specify which network interfaces are used to execute Group Replication recovery.
.1 we can:
SET @@GLOBAL.group_replication_advertise_recovery_endpoints = "192.168.0.1:3306";
To enable the use of endpoint
192.168.0.1:3306 on Group Replication recovery when using server
.1 as donor.
We continue to improve Group Replication to better suite the needs of all MySQL users. If you want more information about
group_replication_endpoints please give a look to documentation.
