microservice-utils

Utilities and adapters for speeding up microservice development.

Optional Dependencies (Extras)

The package offers optional functionality through extras. Extras can be installed with the package using the following syntax:

pip install microservice-utils[gcp_pubsub]

Available extras:

• events: Support for event-driven architectures using pydantic for data validation and parsing.
• gcp_cloud_run: Support for Google Cloud Run with the google-cloud-run client library.
• gcp_cloud_tasks: Support for Google Cloud Tasks with the google-cloud-tasks client library.
• gcp_pubsub: Support for Google Cloud Pub/Sub using the google-cloud-pubsub client library and tenacity for retries.
• openai: Support for completions with the OpenAI API.
• pinecone: Support for semantic search with Pinecone.

To install multiple extras, separate them with commas:

pip install microservice-utils[events,gcp_cloud_run,gcp_cloud_tasks,gcp_pubsub,openai,pinecone]

GCP Pub/Sub

You can subscribe to multiple subscriptions by subsequently calling subscribe(). wait_for_shutdown will block IO for all the subscriptions and wait for the app to be signaled to shut down.

from microservice_utils.google_cloud.adapters.pubsub import Subscriber

subscriber = Subscriber("your-gcp-project-id", prepend_value="staging")

with subscriber:
    subscriber.subscribe(
        "accounts__users", sample_handler
    )

    try:
        subscriber.wait_for_shutdown()
    except KeyboardInterrupt:
        # Gracefully shut down in response to Ctrl+C (or other events)
        subscriber.shutdown()
