Understanding Flyte's Dynamic Workflows: How They Power Scalable ML Pipelines
- Flyte Workflows define pipelines as Directed Acyclic Graphs (DAGs), ensuring efficient compute but requiring new DAG executions from the beginning or intermediate points.
- Flyte's workflow lifecycle involves compile time (serialization, packaging, uploading) and run time, focusing on speed and efficiency by using Promises instead of direct evaluation.
- Tasks and workflows differ in evaluation timings, with workflows structured at registration time and tasks lazily evaluated at compile and executed at run time.
- Dynamic workflows in Flyte combine task and workflow features, building DAG structures at runtime and returning Promise objects for async evaluation.
- An example in the article showcases dynamic workflow usage for ML tasks, combining data preprocessing, model training, and hyperparameter tuning efficiently.
- Dynamic workflows offer flexibility by lazily evaluating inputs and enable dynamic runtime input definitions, ideal for scenarios like hyperparameter optimization.
- A combination of dynamic workflows and MapTasks can enhance parallel processing, as illustrated in the transformed ML pipeline example presented.
- The article highlights the speed benefits of parallel processing in dynamic workflows, achieving a 20% faster execution compared to traditional methods.
- Flyte's Dynamic Workflows provide dynamism for user-defined inputs at runtime, catering to modern use cases like LLMs and offering both flexibility and efficiency.
