Struct DdlOptions 

Source 
pub struct DdlOptions {
    pub timeout: Duration,
    pub wait: bool,
}
Expand description

The options for DDL tasks.

Note: These options may not be utilized by all procedures. At present, they are specifically applied in RepartitionProcedure and truncate tasks.

Fields§

§timeout: Duration

The timeout will be passed to the procedure.

Note: Each procedure may implement its own timeout handling mechanism. For truncate tasks, the timeout bounds submission and waiting rather than procedure execution. A timeout does not cancel a submitted procedure.

§wait: bool

The flag that controls whether to wait for the procedure to complete.

If wait is true, the procedure will wait for completion(success or failure) and the result will be returned. Otherwise, the procedure will be submitted and return the ProcedureId immediately.

Note: Except for truncate tasks, the value of wait is independent of the timeout option. If a procedure ignores the timeout and wait is set to true, the operation returns until the procedure completes.
