func SlowStartBatch

func SlowStartBatch(count int, initialBatchSize int, shortCircuit bool, fn func(int, error) error) (int, error)

SlowStartBatch tries to call the provided function a total of 'count' times, starting slow to check for errors, then speeding up if calls succeed.

It groups the calls into batches, starting with a group of initialBatchSize. Within each batch, it may call the function multiple times concurrently.

If a whole batch succeeds, the next batch may get exponentially larger. If there are any failures in a batch, all remaining batches are skipped after waiting for the current batch to complete.

It returns the number of successful calls to the function.
