Installation

The core package gives you the primitives. Each runtime is a separate package that depends on the core, so you install only what you use.

pip install pyrula

from pyrula import Either, Option, Try

Runtime packages

Package	Install	Import
Workflows	pip install pyrula-workflows	pyrula.workflows
Agents	pip install pyrula-agents	pyrula.agents
Kafka	pip install pyrula-kafka	pyrula.kafka
Connectors	pip install 'pyrula-connectors[delta]'	pyrula.connectors
Pipelines	pip install pyrula-pipelines	pyrula.pipelines

Installing any of these pulls in pyrula.

Requirements

Python 3.11 or newer. Workflows durability needs Valkey 7.4+ or Redis 7.0+. Event archival is optional and uses Postgres.

Durability config

Workflows read their store and archival targets from the environment:

export PYRULA_VALKEY_URL=redis://localhost:6379
export PYRULA_POSTGRES_DSN=postgresql://user:pass@localhost:5432/pyrula_events

The redis:// scheme covers both Valkey and Redis. Full config lives under Workflows.

Check it

python -c "from pyrula import Either, Option, Try; print('ok')"
