It provides two decorators (`@register_before_snapshot` and `@register_after_restore`) and corresponding function-based registration methods to control initialization and cleanup around snapshot boundaries. The library has no runtime dependencies and is already bundled in Lambda runtime environments, making it a zero-friction addition to SnapStart-enabled functions.\n\nThe main use case is optimizing Lambda cold starts by deferring expensive initialization (database connections, external API calls, resource setup) until after a snapshot is restored, rather than on every invocation. BeforeSnapshot hooks run in reverse registration order; AfterRestore hooks run in registration order. Hooks must be registered at module level to be recognized; registering them inside the handler or in unimported files will be silently ignored.","worth_installing":"Yes, if you are using AWS Lambda SnapStart with Python. The library is already pre-installed in Lambda runtimes, so you only need to add it to local development dependencies for testing. It has no external dependencies, a permissive license, and solves a specific optimization problem. Maintenance is dormant but the API is stable and the scope is narrow, so active updates are not critical."},"id":"snapshot-restore-py","links":{"html":"https://skillfed.io/packages/snapshot-restore-py","md":"https://skillfed.io/packages/snapshot-restore-py.md","pypi":"https://pypi.org/project/snapshot-restore-py/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2024-11-13","license_spdx":null,"license_treatment":"permissive","name":"snapshot-restore-py","python_support":"supports_current","summary":"Runtime Hooks for AWS Lambda SnapStart - Python"},"popularity":{"monthly_downloads":2681307,"position":2943,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.0.0"}
