• For issues related to the code in this repository file a GitHub issue.
• If the issue pertains to Cloud Firestore, report directly in the
  Python Firestore GitHub repo. Firestore
  bugs reported in this repo will be closed with a reference to the Python Firestore
  project.
• For general technical questions, post a question on StackOverflow
  with the firebase tag.
• For general Firebase discussion, use the firebase-talk
  google group.
• For help troubleshooting your application that does not fall under one
  of the above categories, reach out to the personalized
  Firebase support channel.

[REQUIRED] Step 2: Describe your environment

• Operating System version: Amazon Linux 2
• Firebase SDK version: unknown
• Firebase Product: messaging
• Python version: 3.9
• Pip version: 22.1.2

[REQUIRED] Step 3: Describe the problem

This library's dependency on all of google-api-python-client pulls in 50+MB of code, causing our AWS Lambda deployment to be over AWS's package size limit.

Does this library really need to depend on all of google-api-python-client? As per https://pypi.org/project/google-api-python-client/ "There is a separate client library for each API, so you can choose which client libraries to download. Whereas, google-api-python-client is a single client library for all APIs. As a result, the total package size for google-api-python-client exceeds 50MB."

Steps to reproduce:

Depend on this library.

I have the same issue.

I have made a feature request to Firebase support regarding this issue to be able to split the packages when installing firebase-admin and when we only use firebase-messaging for example.

I'm also having the same issue but didn't find any solution so far.

This is a major issue. Even the README.md at https://github.com/googleapis/google-api-python-client says:

The maintainers of this repository recommend using Cloud Client Libraries for Python, where possible, for new code development due to the following reasons:

With Cloud Client Libraries for Python:

• There is a separate client library for each API, so you can choose which client libraries to download. Whereas, google-api-python-client is a single client library for all APIs. As a result, the total package size for google-api-python-client exceeds 50MB.
• There are stricter controls for breaking changes to the underlying APIs as each client library is focused on a specific API.
• There are more features in these Cloud Client Libraries as each library is focused on a specific API, and in some cases, the libraries are owned by team who specialized in that API.
• Developers will benefit from intellisense.

I strongly suggest that this codebase should be migrated to use the packages in https://github.com/googleapis/google-cloud-python instead.
