   The signal table feature is a huge milestone for Debezium.
   It provides a command pattern based on a source database table to send commands (aka signals) to Debezium so that specific actions may be taken.
  -The signal table framework is extendable, meaning that a connector can implement its own custom commands as needed.
  +The framework is extendable, allowing a connector to implement custom commands beyond the common commands provided by Debezium core.
  +There are several situations where this might be applicable, including but not limited to,
  +PostgreSQL primary key column changes,
  +changes to enum value-sets of a column definition,
  +and schema changes with the Oracle connector.
  +This is an incubating feature and therefore behavior is subject to change between releases.
   
   In order to use the signal table feature, the connector option `signal.data.collection` must be specified in the connector's configuration.
   This option specifies the fully qualified name of the table from which signal requests will be sourced.
  
positive.code: Rather than this conversion be implicitly done by the connector, this behavior has been moved to an OOTB converter, `NumberOneToBooleanConverter`,
  that can be used as needed (https://issues.redhat.com/browse/DBZ-3208[DBZ-3208]).
