When it comes to DBU, I am being charged by Azure for the following meters:

- Premium Jobs Compute DBU <-- DBUs that my job computes are spending
- Premium Serverless SQL DBU <-- DBUs that the SQL Warehouse compute is spending
- Premium All-Purpose Photon DBU <-- Photon DBUs that Personal Computes are spending
- Premium All-purpose Compute DBU <-- DBUs that Personal Computes are spending
- Premium Automated Serverless Compute DBU <-- ???
- Premium Interactive Serverless Compute DBU <-- ???
- Premium Jobs Compute Photon DBU <-- Photon DBUs that jobs computes are spending

Can someone advise if my understanding is correct and clear the remaining meters which I cannot explain?

Also how those these maps to Databricks SKUs coming from system.billing table:

- PREMIUM_JOBS_SERVERLESS_COMPUTE_US_EAST_2
- PREMIUM_JOBS_COMPUTE_(PHOTON)
- PREMIUM_ALL_PURPOSE_SERVERLESS_COMPUTE_US_EAST_2
- PREMIUM_ALL_PURPOSE_COMPUTE_(PHOTON)
- PREMIUM_SERVERLESS_SQL_COMPUTE_US_EAST_2
- PREMIUM_ALL_PURPOSE_COMPUTE
- PREMIUM_JOBS_COMPUTE

Many thanks!
