How-To

Each page here does one task, step by step, with code that you can run. To see what a part of desflow does and all its options, see the User Guide. For a complete model to download and run, see the Runnable Examples group.

Group	What it covers
Modelling	arrival rates and staffing that change at set times, tasks that leave a queue or refuse to join it, waits for the first or all of several things, handoffs between resources, a resource shared by weight, breakdowns and repairs, and resources added during a run
Records and Kafka	records routed to Kafka topics, Avro and Pydantic records, secure Kafka connections, and connectors of your own
Analysis	distributions fitted to measured times, checks against the queueing formulas, tests for a model, and a run's event log, analysed and animated
Tools	Python logic in a blueprint, completion and checks for blueprints in an editor, an AI coding assistant, and the fastest data generation
Runnable Examples	complete models to download and run: a local simulation, a Kafka digital twin, history written fast to Parquet or Iceberg, PostgreSQL, Redis, history then live records, and related records
