    Description

      Hi,
      we want to use Debezium MongoDB connector to get snapshots and changes from replicated cluster. From what I found in documentation MongoDB connector is always reading from primary node, which is not acceptable for our case as it may affect the whole cluster performance.
      For usual reads we are using read preference with tag sets to read from specific nodes, and I propose to implement such feature for Debezium too? I understand that secondary may have replication lag, but this may be acceptable in many cases.
