Before you install
- Requires a gRPC config file in text protobuf format defining ChannelPoolConfig and MethodConfig; package targets Python 2.7 and Python 3.4–3.6.
- Low install friction with a single runtime dependency on grpcio.
- However, the package is abandoned—last release was 2018-09-10 with no updates since, and classifiers indicate support only for Python 2.7 and Python 3.4–3.6.

What it is and what it does
grpcio-gcp is a gRPC extension that adds connection pooling and affinity-based request routing for Google Cloud Platform services. It wraps the standard gRPC channel to manage a pool of underlying channels and route requests to specific backend instances based on configuration rules, useful for services that benefit from session affinity.
The package works by loading an API configuration file in text protobuf format that defines channel pool parameters and per-method routing rules, then providing a secure_channel factory that returns a channel pool object compatible with the standard gRPC Channel interface. It is a specialized tool for GCP service integration rather than a general-purpose gRPC enhancement.
Use it for
- Manage connection pooling to Google Cloud services that require session affinity and benefit from multiple underlying channels.
- Bind gRPC requests to specific backend instances using affinity keys to maintain session state across method calls.
- Configure per-method routing rules (BIND, BOUND, UNBIND) to control how requests are distributed across a pool of channels.
