API Cursor Pagination Performance : conversations.list

The behavior characteristics and performance of iterating the cursor through conversations.list is truly awful when it is being used to resolve a channel name to a channel id.

For example, if I create a new channel in an org that's been around for a while, with limit=200, that channel is returned on page 135, and the pagination sequence takes 7m38.503s to resolve with 20 calls per minute (tier 2 rate limit).
When inspecting the responses, it can be seen that the channels returned never reach the limit count, and progressively diminish, eventually returning no results across cursors, sometimes 2, sometimes 10, etc., until finally resolving.

Please, either create a new class of methods that support resolving user or channel names directly to their IDs, or optimize the data that feeds the pagination to enable the methods to return valuable data earlier in the pagination sequence.

This is related to the last bullet under Just The Facts:

It's possible to receive fewer results than your specified limit, even when there are additional results to retrieve.

Note
This started when looking at chat.update and seeing that it required a channel id rather than a channel name (I tested it and it's not just a docs issue...). Rather than fixing the above situation, if you can align the chat.postMessage and chat.update methods to both accept a channel name, then that would satisfy my original problem. Though, the above deficiency will still exist. I've made a separate issue for this here.

Bắt đầu với các entry point của slack_sdk.web.WebClient cho conversations.list, chat.update và chat.postMessage, sau đó kiểm tra cách phân trang bằng cursor và việc xử lý tên kênh được cung cấp. Issue đưa ra nhiều giải pháp khả thi, vì vậy để hoàn thành cần lựa chọn và xác định rõ SDK sẽ phân giải tên trực tiếp, tối ưu hóa phân trang hay đồng bộ các method liên quan đến message, với các test bao phủ hành vi đã chọn.
