在Spring客户端实现中，有没有更好的方法可以同时调用REST API？

Question

I'm implementing one service which is internally calling some third party rest API to get the data and process over it. API call can be N number of times based on different user input data, so it can call the API 100 times or 10000 times as well and each API call takes 1-2 seconds on an average that will increase the total time for overall process.

I want to understand if there's any best way to handle such problem smoothly? I was planning for concurrent API call about 100 times or 1000 times(thread running using @async spring boot method) but again this number of threads execution speed will depend on the system it is running on.

Your reply will be great help, Thanks in advance.

Give a try to reactor project. It requires some effort if you want to be efficient with it, but the code would be pretty simple and if you use Spring 5/Boot 2 then you could take advantage of NIO Spring Web Client. Otherwise it will be similar to what you've suggested - run concurrently X API calls
