First, data persistenceDiydb is a document-based database (not an in-memory database), and he needs to persist the data, and read and write data on disk. How is it more efficient to read and write data on disk? The current approach to Linux is to

BackpressureThe data stream in Rx is emitted from one place to another. The speed at which each place processes data is different. What happens if the producer launches the data faster than the consumer can handle? In a synchronous operation, this
