anchor.diff:  |`2000`
   |Specifies the maximum number of rows that should be read in one go from each table while taking a snapshot.
   The connector will read the table contents in multiple batches of this size. Defaults to 2000.
  +
  +|`source.struct.version` +
  +0.10 and later
  +|v2
  +|Schema version for the `source` block in CDC events; Debezium 0.10 introduced a few breaking +
  +changes to the structure of the `source` block in order to unify the exposed structure across
  +all the connectors. +
  +By setting this option to `v1` the structure used in earlier versions can be produced.
  +Note that this setting is not recommended and is planned for removal in a future Debezium version.

  |Mode to control which transaction isolation level is used and how long the connector locks the monitored tables. There are four possible values `read_uncommitted`, `repeatable_read`, `snapshot`, and `exclusive`. + 
  
  `repeatable_read` In this mode connector will use exclusive locks only during schema snapshot. +
