[Question] Does a single queryRadius call possibly run multiple queries?

[ghost]

Hello,

I see that queryRadius method calls dispatchQueries that is defined in src/GeoDataManager.ts which in turn produces hashKeys in the covering area, and execute each query.

export class GeoDataManager {
  private async dispatchQueries(covering: Covering, geoQueryInput: GeoQueryInput) {
    const promises: Promise<DynamoDB.QueryOutput[]>[] = covering.getGeoHashRanges(this.config.hashKeyLength).map(range => {
      const hashKey = S2Manager.generateHashKey(range.rangeMin, this.config.hashKeyLength);
      return this.dynamoDBManager.queryGeohash(geoQueryInput.QueryInput, hashKey, range);
    });

    const results: DynamoDB.QueryOutput[][] = await Promise.all(promises);
    const mergedResults = [];
    results.forEach(queryOutputs => queryOutputs.forEach(queryOutput => mergedResults.push(...queryOutput.Items)));
    return mergedResults;
  }
}

Is my understanding true that a query will be executed for each item in covering.getGeoHashRanges(this.config.hashKeyLength)?
