Why do I need 16 cores or more for a DEMO? #122

Open jhrobinson opened 6 months ago

jhrobinson commented 6 months ago

I have received the following error message more than once. Even when I use the trial version, I get the same error message. Why do I need so many cores for a demo?

thanks for flagging this, which demo is doing that? You can run it with use_current_cluster = True to avoid the issue while we check the demo setup.

jhrobinson commented 6 months ago

Two of them: dbdemos-lakehouse-fsi-credit dbdemos-lakehouse-retail-c360.

How do I set use_current_cluster = true?

QuentinAmbard commented 6 months ago

just in the install function, you can run dbdemos.help() It'll prevent from starting a new cluster

jhrobinson commented 6 months ago

So like this?

dbdemos.help(use_current_cluster = true)

QuentinAmbard commented 6 months ago

dbdemos.install("lakehouse-retail-c360", use_current_cluster = true)

I added the code you wrote above. No errors, but shouldn't there be a new schema added to UC?

jhrobinson commented 6 months ago

Is this demo created in such a way that you can't deviate at all? It seems that there are all kinds of issues if you can't use a certain workspace or cluster.

@jhrobinson the install will create a job and use your current cluster to run the job, the job will create a schema/catalog and save the data here. You can check the job for more details you have the link in the install report. Make sure your cluster is ML runtime + UC enable (single user is probably easier)
