SDK for Momento

Momento Python Client Library

Momento Cache is a fast, simple, pay-as-you-go caching solution without any of the operational overhead required by traditional caching solutions. This repo contains the source code for the Momento Python client library.

To get started with Momento you will need a Momento Auth Token. You can get one from the Momento Console.

Packages

The Momento Python SDK package is available on pypi: momento.

Usage

The examples below require an environment variable named MOMENTO_API_KEY which must be set to a valid Momento API key. You can get one from the Momento Console.

Python 3.10 introduced the match statement, which allows for structural pattern matching on objects. If you are running python 3.10 or greater, here is a quickstart you can use in your own project:

from datetime import timedelta

from momento import CacheClient, Configurations, CredentialProvider
from momento.responses import CacheGet

cache_client = CacheClient(
    Configurations.Laptop.v1(), CredentialProvider.from_environment_variable("MOMENTO_API_KEY"), timedelta(seconds=60)
)

cache_client.create_cache("cache")
cache_client.set("cache", "my-key", "my-value")
get_response = cache_client.get("cache", "my-key")
match get_response:
    case CacheGet.Hit() as hit:
        print(f"Got value: {hit.value_string}")
    case _:
        print(f"Response was not a hit: {get_response}")

The above code uses structural pattern matching, a feature introduced in Python 3.10. Using a Python version less than 3.10? No problem. Here is the same example compatible across all versions of Python:

from datetime import timedelta

from momento import CacheClient, Configurations, CredentialProvider
from momento.responses import CacheGet

cache_client = CacheClient(
    configuration=Configurations.Laptop.v1(),
    credential_provider=CredentialProvider.from_environment_variable("MOMENTO_API_KEY"),
    default_ttl=timedelta(seconds=60),
)
cache_client.create_cache("cache")
cache_client.set("cache", "myKey", "myValue")
get_response = cache_client.get("cache", "myKey")
if isinstance(get_response, CacheGet.Hit):
    print(f"Got value: {get_response.value_string}")

Getting Started and Documentation

Documentation is available on the Momento Docs website.

Examples

Working example projects, with all required build configuration files, are available for both Python 3.10 and up and Python versions before 3.10:

• Python 3.10+ examples
• Pre-3.10 Python examples
