09/21/2023, 11:03 AMhi everyone,
can we initiate multiple sessions in kedro? if yes, could anyone help me with it?
kedro version - 0.18
i am building a web application where in i have to trigger the different pipelines of a kedro project based on button clicks on the dash ui.
as of now, individually it is working, but when one session is running, if i tries to trigger another session it gives a runtime error.

09/21/2023, 12:36 PMDo you need to keep track of the session_id? If not you can try to use the lower level component such as
DataCatalogRunner Copy code
context = session.load_context()
catalog = context.catalog
runner = SequentialRunner()
runner.run(<pipeline>, catalog)m

Hey @Nok Lam Chan, I was trying this, but have some doubts. can we connect for a short time to understand it better?
one more issue is i have to trigger a set of pipelines for each button clicks and these pipelines are mutually exclusive.

Assuming one had to “_keep track of the session_id_”…
What is the best way to do it ?
catalog._save_versionm

Now that you say it, it just sounds completely obvious.
I guess I just got lazy and since I had the catalog object available I used the
_save_version
