Dynamic YES

The JDBC URL to connect to the database.

Dynamic YES

SQL to execute atomically after trigger query.

Optional SQL executed in the same transaction as the main trigger query. Typically updates processing flags to prevent duplicate processing. Both sql and afterSQL queries commit together, ensuring consistency.

Dynamic NO

DEPRECATED, please use fetchType: FETCH instead. Whether to fetch the data from the query result to the task output. This parameter is evaluated after fetchOne and store.

Dynamic NO

Default false

DEPRECATED, please use fetchType: FETCH_ONE instead. Whether to fetch only one data row from the query result to the task output. This parameter is evaluated before store and fetch.

Dynamic NO

Default 10000

Number of rows that should be fetched.

Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for this ResultSet object. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. Ignored if autoCommit is false.

Dynamic YES

Default NONE
