> Is this similar to the plug-in [batch-request](https://apisix.apache.org/docs/apisix/plugins/batch-requests/)？ No, this plugin is different from the batch-requests plugin in several ways. Key Differences: 1. Purpose: Your plugin (proxy-chain) is designed to sequentially call multiple backend services, merge their responses, and forward the final merged data to the upstream. batch-requests allows clients to send multiple requests in a single HTTP call, and it executes them in parallel (or optionally in sequence), returning all responses back to the client as a batch. 2. Response Handling: proxy-chain merges the responses of the services into one unified request body that is then forwarded upstream. batch-requests returns the raw responses of each sub-request as separate items in an array. 3. Flow Direction: proxy-chain is used in the request phase, before the final upstream is called. It acts as a transformation layer before reaching the main backend. batch-requests is mostly client-driven — clients explicitly request multiple things, and the plugin acts more like a batch router. 4. Use Case: Use proxy-chain when you want to call multiple internal services, combine their outputs, and proceed with the final data as if it was one logical request. Use batch-requests when a frontend or client needs to hit multiple endpoints in a single API call and receive all results independently. -- This is an automated message from the Apache Git Service.
