In other words, the first schema field describes the structure of the primary key, or the unique key if the table does not have a primary key, for the table that was changed. It specifies a Kafka Connect schema that describes what is in the event key’s payload portion. The first schema field is part of the event key. Overview of change event basic content Item If you do not specify a value, the connector runs an incremental snapshot. Specifying a type value in the SQL query that you submit to the signaling table is optional. The array lists 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. Specifies 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 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 Value The following table describes the these parameters: Table 5. If MySQL applies them individually, the connector creates a separate schema change event for each statement.Īn array of one or more items that contain the schema changes generated by a DDL command. If MySQL applies them atomically, the connector takes the DDL statements in order, groups them by database, and creates a schema change event for each group. Multiple DDL statements appear in the order in which they were applied to the database.Ĭlients can submit multiple DDL statements that apply to multiple databases. The ddl field can contain multiple DDL statements.Įach statement applies to the database in the databaseName field. This field contains the DDL that is responsible for the schema change. ![]() The value of the databaseName field is used as the message key for the record. Identifies the database and the schema that contains the change. This field is useful to correlate events on different topics. The source field is structured exactly as standard data change events that the connector writes to table-specific topics. Descriptions of fields in messages emitted to the schema change topic Item "ddl": "CREATE TABLE products ( id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255) NOT NULL, description VARCHAR(512), weight FLOAT ) ALTER TABLE products AUTO_INCREMENT = 101 ", Try (Connection conn = DriverManager.getConnection( register JDBC driver, optional since java 1.6 auto discovery - no longer need to load a class via Class.forName
