What exactly is a read/write operation in cloud storage? Is it possible to combine several write requests into one single requests?

Hello guys, I am new to web development and related technologies. I would like to know whether each get request is a read operation and post, put and delete are write operations?

Is it possible to combine several write requests and do it as a single write request? For example, if someone likes a post, instead of writing that directly to database, is it possible to hold the request somewhere temporarily before writing it together with other similar requests?

Thanks
