{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Enable DirectPath support for gRPC workflows","articleBody":" **Is your feature request related to a problem? Please describe.**\r\nThe current behavior for grpc does not utilize DirectPath. DirectPath leads to improved latency for request originating from GCE VMs and `gcloud storage` relies on this feature.\r\n\r\n **Describe the solution you'd like**\r\nTwo changes are needed:\r\n\r\n\r\n1. Replace: https://github.com/googleapis/python-api-core/blob/b6eb6dee2762b602d553ace510808afd67af461d/google/api_core/grpc_helpers.py#L267\r\nwith:\r\n```\r\nif compute_engine_channel_credentials_requested:\r\n  return grpc.compute_engine_channel_credentials(google_auth_credentials)\r\nelse:\r\n  grpc.composite_channel_credentials(ssl_credentials, google_auth_credentials)\r\n```\r\nwhere, compute_engine_channel_credentials_requested will be a `bool` passed to the `create_channel` call. Alternatively, it can rely on the env variable like it's done for other languages \r\n\r\n2. Add the `google-c2p` resolver. This can be similar to how other languages e.g. go handles it https://github.com/googleapis/google-api-go-client/blob/8d8f0a70d0bd6ba4daaa08370d1420f759ff7f9d/transport/grpc/dial.go#L182\r\n\r\n **Describe alternatives you've considered**\r\nFor `#2` above, we can potentially update the [GAPIC client generator](https://github.com/googleapis/gapic-generator-python) to create the host name with `google-c2p:///` prefixed. But I think given that all other languages are handling it in the middleware, it is appropriate to make this change in this library.\r\n\r\n **Additional context**\r\nThere is an internal bug related to this, but I'm not sure if I link it on a public repo.\r\n","author":{"url":"https://github.com/dilipped","@type":"Person","name":"dilipped"},"datePublished":"2023-02-03T17:30:46.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/482/python-api-core/issues/482"}
