## Description:

Is K8-PXC support bi-directional replication ?

Because we can not use **isSource**  **true** & **false** together in “spec.pxc.replicationChannels”

Operator error:

Hello @Lalit_Choudhary,  
No, the PXC operator does not support source/source replication. The replication is one-way only.
