Hello brother.
I have configured mysql innodb cluster. In my cluster I have 3 nodes for cluster and one app server where I install mysql router. When I disconnect one nodes from cluster it automatically switch another nodes but running transactions on node1 are being failed during nodes transfer. I am controlling this using app server where I use mysql router. My router automatically switch node1 to node2 when node1 disconnect. But there are some queries running on node1. Queries are failed when router automatically switch from node1 to node2 during node 1 shutdown. How can I recover this data loss ? my all running queries are failed during node switch in inno db cluster. Is there any solution to fix this data loss ??
