Retry for rows that return retryable error codes. by justinseinlin · Pull Request #4116 · googleapis/google-cloud-python

justinseinlin · 2017-10-03T22:27:29Z

Retry some mutations that are retryable using similar mechanism as google.gax.retry.retryable.
However, we can't use retryable since it raises a RetryError upon final timeout. We want to return responses list with corresponding status codes for the given rows to be mutated.

PS: Creating a PR first to see if we agree on the implementation and how we want to configure the retry parameters (which are currently set locally since no other methods are using it). Will add test cases in another commit.

This definitely looks like its on the right track to me. Just a few initial comments...

I pushed a commit to just fix the lint errors first. But linter output is now unmanageably huge since it's checking inside google.cloud.bigtable._generated. Isn't that blocked by .flake8?

Closesgoogleapis#4123.

Going to close this PR since I made a mistake in doing a rebase with commits already on the remote.
A new PR is created with just the relevant commits cherry-picked on top of master HEAD for api.core -> api_core refactoring: #4256
