(There should be a separate section of this forum for Spanner)

I'd like Spanner to offer a simple API for atomically incrementing or decrementing a counter. Currently, we have to read a record, increment and write back. Compared to regular SQL `SET x = x + 1`, or DynamoDB which offers an increment operation, this is much more programmer overhead.

Plus, it allows race conditions where multiple writers are incrementing a column, even given Spanner's external strong consistency, if both read the same value before one writes back an incremented amount. This makes it hard to keep denormalised counts accurate over time.

GCP Billing export shows up all costs and credits that will be billed, or were already billed for a specific billing account.

It would be nice, if I could see which costs were already payed / or shown on a monthly bill, and which will show up on the next bill.

Right now I can't tell exactly what amount will show up on my monthly bill, by evaluating the billing export data.

Could there be a reference to a bill, or at least a flag "was_billed" or something else in the billing export data?

I know, an additional column may be difficult, because the Billing export just exports the current costs/credits, but perhaps just a additional row in the export data could be inserted, stating that all lines above were already payed / referenced in a bill.
