Details

    Description

      According to the document:https://debezium.io/documentation/reference/1.7/connectors/mysql.html#_ad_hoc_read_only_incremental_snapshot

      An alternative way to signalling table mechanism to execute a new snapshot when the MySQL connection is read-only is to send a message to the Kafka topic configured with signal.kafka.topic property.
      
      The key of the Kafka message has to match the connector’s name.
      
      The value is a json with type and data fields.The signal type is execute-snapshot and the data field must have the following fields:Table 4. Execute snapshot data fields
      

      It described that the key of the Kafka message has to match the connector’s name.

       

      From the test log, i found found that database.server.name needs to be passed in instead of connectorName .
