transaction throughput with incomplete keys?

Question

According to the docs at https://cloud.google.com/appengine/docs/go/datastore/entities "There is a write throughput limit of about one transaction per second within a single entity group"

Does this apply to incomplete keys, such that using incomplete keys in a transaction will limit it to only one transaction?

Answer 1

If you mean incomplete keys as in you are letting the system generate the id, then and it is in an entity group then the same rate limit to writes to that entity group.

If it's in a different entity group then no.

Remember the rate limit is per entity group, irrespective of how the keys are generated.
