Hi @fanjinfei many thanks for this. In general can you provide a short description of what the changes introduced do in the PR description and the commit messages? This is useful when other developers check the code in the future and want to know the context of them and what to expect.

I don't think that the function name describes well what it does. If I understood correctly, something like datastore_run_triggers would me more accurate right?

And on the docstring, perhaps replace:

The datastore_trigger_each_row API action allows you to apply triggers to an existing DataStore resource.

with

The datastore_run_triggers API action allows you to re-apply existing triggers to an existing DataStore resource.

WDYT?
