When a pipeline runs against many third-party endpoints, that fixed budget can cost ~80 minutes on a single dataset whose endpoint times out repeatedly on heavy queries — light stages on the same endpoint then sit behind the heavy ones that will never succeed. + +A `TimeoutPolicy` decides the budget for each SPARQL request and observes the outcome.

Validation operates on the **combined output of all executors per batch**, not on individual quads or per-executor output. A batch produces a complete result set — a self-contained cluster of linked resources — that can be meaningfully matched against SHACL shapes. Even with a single executor, each batch is a complete unit; with multiple executors, shapes that reference triples from different executors are validated correctly. diff --git a/packages/pipeline/src/pipeline.ts b/packages/pipeline/src/pipeline.ts index acee7116..43906810 100644 --- a/packages/pipeline/src/pipeline.ts +++ b/packages/pipeline/src/pipeline.ts @@ -24,6 +24,10 @@ import type { ProgressReporter, } from './progressReporter.js'; import type { Validator } from './validator.js'; +import { + ConstantTimeoutPolicy, + type TimeoutPolicy, +} from './sparql/timeoutPolicy.js'; /** Plugin that hooks into pipeline lifecycle events. */ export interface PipelinePlugin { @@ -44,6 +48,17 @@ export interface PipelineOptions { outputDir: string; }; reporter?: ProgressReporter; + /** + * Factory producing a fresh {@link TimeoutPolicy} per dataset.
