, obtains the process result, and then invokes execution to proceed.Working principleAt runtime, a client-to-server RPC call, with an internal operation of roughly 10 steps, is as follows:1. Invoking the client handle; executing the transfer parameters2. Call the local system kernel to send a network message3. Messaging to a remote host4. Server handle get message and get parameters5. Performing a remote procedure6. The execution process returns the result to the server handle7. Server handle re

The so-called RPC is a remote method call, or simply by mq,tcp,http or the network protocol you write to transmit what I want to call the other side of the interface, the other side processing and then return the results to me.

Fragmentation is a way of mongodb expansion. The fragment splits a collection and stores the different parts on different machines. When the collections phase of a database is too large for the current space, you need to add a new machine. Fragmentation automatically distributes collection data to new servers. 1.
