Prefect Tasks¶

Tasks are the easiest Prefect execution surface to adopt. Use them when a flow already exists and you want to insert validation without committing to persisted block configuration yet.

Pre-built Tasks¶

`data_quality_check_task`¶

Use it for standard validation inside a flow.

`data_quality_profile_task`¶

Use it when the flow should profile a dataset.

`data_quality_learn_task`¶

Use it to learn candidate rules from baseline data.

Specialized Tasks¶

Other useful helpers include:

strict and lenient check presets
auto-schema check helpers
profile presets
streaming tasks

Task Factories¶

Use create_check_task, create_profile_task, and related factory helpers when you want reusable task construction without rewriting shared logic.

Task Configuration¶

CheckTaskConfig, ProfileTaskConfig, and LearnTaskConfig expose task-level policy choices while keeping task wiring consistent.

Task Chaining¶

Prefect tasks compose well when you separate load, validate, profile, notify, and persist steps.

Using With Blocks¶

Pass a DataQualityBlock when the flow should consume saved configuration instead of ephemeral defaults.

Retry Configuration¶

Keep business logic retries and platform retries understandable. Do not hide configuration mistakes behind excessive retry settings.
