![]() ![]() You can specify different filters for each data collection. If you do not specify a value, the connector runs an incremental snapshot.Īn optional array that specifies a set of additional conditions that the connector evaluates to determine the subset of records to include in a snapshot.Įach additional condition is an object with data-collection and filter properties. The array lists regular expressions which match tables by their fully-qualified names, using the same format as you use to specify the name of the connector’s signaling table in the configuration property.Īn optional type component of the data field of a signal that specifies the kind of snapshot operation to run.Ĭurrently, the only valid option is the default value, incremental. The type parameter specifies the operation that the signal is intended to trigger.Ī required component of the data field of a signal that specifies an array of table names or regular expressions to match table names to include in the snapshot. Rather, during the snapshot, Debezium generates its own id string as a watermarking signal. Use this string to identify logging messages to entries in the signaling table. The id parameter specifies an arbitrary string that is assigned as the id identifier for the signal request. Specifies the fully-qualified name of the signaling table on the source database. Descriptions of fields in a SQL command for sending an incremental snapshot signal to the signaling table Item The following table describes the parameters in the example: Table 2. ![]() Running an incremental snapshot captures the following data changes: The connector runs the snapshot while it continues to stream real-time changes from the tables. (Optional) If the connector performed a schema_only snapshot, after the snapshot completes, initiate an incremental snapshot to capture data from the tables that you added. The connector completes the type of snapshot specified by the snapshot.mode. Use this option if you want to restart the connector more quickly than with a full snapshot. Unlike a full data snapshot, this option does not capture any table data. ![]() When you restart the connector, it takes a snapshot that captures only the table schema. If you select this option, consider setting the value of the .tables.ddl property to false to enable the connector to capture the schema of all tables. When you restart the connector, it takes a full snapshot of the database that captures the table data and table structures.
