BODS: How to execute data flow in parallel?

Former Member — Fri, 18 Jan 2019 08:24:34 GMT

Requirement:

Two or more data_flow need to be executed in parallel.

When ALL these data_flow are executed completely (either success or failed), then execute next data_flow.

Can it be done?

Below is illustration.

For example, both Job_1 and Job_2 need to be executed in parallel. When both jobs are complete executed, then Job_3 can be executed.

If either Job_1 or Job_2 is not yet complete executed, then Job_3 should not be executed.

Use a work flow to run both data flows in parallel. Run the 3rd data flow after the work flow.

Below is further finding on how to use work_flow to acheive parallel + sequential process.

A few work_flow may be required, depending on requirement.

Scenario 1: Single work_flow is enough to achieve below requirement

Scenario 2: Nested work_flow are required to achieve below requirement:

In the last example, you don't need WF_02. Just include DF_03 instead, in parallel with WF_01.

Noted. Thanks for advice.
