Dagster+ Pricing for example ETL

[raayu83]

Hello,

how would an ETL like the following need to be broken down in dagster when using the (multi-) asset functionality and how many credits would it cost to materialize 7 partitions with it?

1. Extracting Data from an API (1 endpoint for aggregate, 2 endpoints for masterdata)
2. Transforming the data (standardising column names, etc) for each of these
3. Loading the data for each of these into separate staging tables
4. Merging the data in each of the staging tables into the main data table

My current idea is you need the following for each materialization:

1. Three ops for Extract
2. Three ops for Transform
3. Three ops for Load
4. Three ops for Merge
5. Three asset materialisations for the multi-asset

Which would be 15 credits x 7 materialisations, or 105 credits.
I'm assuming the same applies for single-run backfills.
Is this correct?
