requestQueue write costs

The post indicates that the running cost of an actor is now predominantly determined by writing to the request queue, rather than the amount of CU it takes. Community members have questions about the cost of writing to the request queue, such as whether batching requests can reduce the cost, and whether using the new RequestQueueV2 (which is still experimental) could be more efficient and cheaper. Some community members suggest exploring alternative approaches like using an in-memory queue to store results. The community members are trying to come up with ideas to make the request queue writes more cost-effective.
