2. This is an advanced use case for str... This is an advanced use case for streaming a high number of symbols on polygon websockets. This uses a combination of uvloop, orjson, aioredis, grouping messages before transmitting and async streaming to achieve high throughput. This can be easily modified or extended to support simpler or more complex use cases. The key idea is keeping the streaming logic fully separate from all the data logic ad reducing the amount of network IO your application has to do. It can be achieved by using message brokers or in memory queues or writing to DBs directly.

   Before i go on to the explanation, keep in mind the difference of IO bound operations, and CPU bound operations. and if possible, recall the short note I commented earlier about which one to use in what situation. It's fine if you don't. You can find that in the very end of this note. But it is nicer to first read the other stuff in sequence.
