Description
Hi all,
According to default setting of readwritesplit, no reads are sent to the master.
However, when I check InnoDB row read metrics on percona, I find that read are sent to master node.
Moreover, when I close slave node for HA test, I find there are no error occur(suppose there may have some error during failover).
How to route read query only to node slave when I using readwritesplit routing?
This is my maxscale configuration:
[server1]
|
type=server
|
address=<%=scope.function_gclookup(['Server1IP'])%> |
port=<%=scope.function_gclookup(['Server1Port'])%> |
protocol=MariaDBBackend
|
|
|
[server2]
|
type=server
|
address=<%=scope.function_gclookup(['Server2IP'])%> |
port=<%=scope.function_gclookup(['Server2Port'])%> |
protocol=MariaDBBackend
|
