The Data API is a large distributed system. To help you take advantage of its scale, we encourage you to horizontally scale parallel requests to the Data API service endpoints. For high-throughput transfers applications you should use multiple connections to retrieve or upload data in parallel. If your application issues request directly to Data API using the REST API, we recommend using a pool of HTTP connections and re-using each connection for multiple requests. Avoiding per-request connection setup removes the need to perform TCP slow-start and Secure Sockets Layer (SSL) handshakes on each request.
