hi team! quick question - if we use dagster to kick off and manage a spark job on EMR, do we need to pay for compute? eg. dagster creates an emr cluster, submits a job that takes 5 hours, and turns down the cluster. the entire pipeline takes 6 hours. the total cost would be: 6 hours x 60 minutes x compute minute price (let's say $0.03) = $10.80
