Function geoparquetResolver

geoparquetResolver(options?: GeoparquetResolverOptions): GeoparquetResolver

Experimental

Build a resolver for createDataset({ resolveSource }) that handles protocol: "geoparquet" descriptors, sharing one GeoparquetRuntime (one DuckDB worker) across every geoparquet source in the dataset — the NFR-001 "single shared worker per client" contract.

Parameters

options: GeoparquetResolverOptions = {}

Returns GeoparquetResolver

Example

import { createDataset } from "@honua/sdk-js/contract";
import { geoparquetResolver } from "@honua/sdk-js/geoparquet";

const geoparquet = geoparquetResolver();
const dataset = createDataset({
  id: "overture",
  client,
  capabilityPolicy: "degraded",
  resolveSource: geoparquet,
  sources: [{
    id: "places",
    protocol: "geoparquet",
    locator: { url: "https://example.com/overture/places.parquet" },
    capabilities: PROTOCOL_DEFAULT_CAPABILITIES.geoparquet,
  }],
});
const places = dataset.source("places")!;
const result = await places.query({ spatialFilter: envelope(-158.5, 21.2, -157.6, 21.7) });
// ...later:
await geoparquet.dispose();
