Hi Waleed,

You have several options:
- Attempt to estimate the size of the entities you're creating by summing up
the size of the fields and adding some overhead, then splitting by size.
- Count the actual size of each entity by using model_to_proto. High
overhead.
- Use a 'divide and conquer' approach, catching RequestTooLargeError
exceptions and splitting the operation in half.
