It exports base classes (SchedulerBase, SchedulerSettingsBase) and interface types (SchedulerDAGInterface, SchedulerJobInterface) that plugin authors must implement to create custom job schedulers. The package itself contains no scheduling logic\u2014it is purely a specification layer that ensures plugins can be discovered and loaded by Snakemake at runtime.\n\nPlugin developers use this interface to implement the select_jobs() method, which receives selectable jobs, remaining jobs, available resources, and input file sizes, then returns a sequence of jobs to execute next. The interface also supports optional configuration via SchedulerSettings and lifecycle hooks like dag_updated(). Plugins must follow the naming convention snakemake-scheduler-plugin-* and be published on PyPI to be recognized by Snakemake.","worth_installing":"Yes, if you are developing a Snakemake scheduler plugin. This is a required dependency for that use case and has low install friction. No, if you are a Snakemake end-user\u2014you do not need this directly. Be aware that the license is unclear in the metadata, so verify the actual license before using in proprietary work. The aging maintenance status (298 days since last release) is typical for a stable interface package but means slower response to compatibility issues."},"id":"snakemake-interface-scheduler-plugins","links":{"html":"https://skillfed.io/packages/snakemake-interface-scheduler-plugins","md":"https://skillfed.io/packages/snakemake-interface-scheduler-plugins.md","pypi":"https://pypi.org/project/snakemake-interface-scheduler-plugins/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-10-20","license_spdx":null,"license_treatment":"unclear","name":"snakemake-interface-scheduler-plugins","python_support":"supports_current","summary":"Scheduler plugin interface for snakemake"},"popularity":{"monthly_downloads":95971,"position":13240,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.2"}
