Steuerung paralleler Asynchron-Batches mit Promise.allSettled

async function processInBatches<T, R>(
  items: T[],
  batchSize: number,
  task: (item: T) => Promise<R>
): Promise<PromiseSettledResult<R>[]> {
  const results: PromiseSettledResult<R>[] = [];
  for (let i = 0; i < items.length; i += batchSize) {
    const chunk = items.slice(i, i + batchSize);
    const chunkResults = await Promise.allSettled(chunk.map(task));
    results.push(...chunkResults);
  }
  return results;
}
