replication latency include network latency, connectivity problems, and disk latency (for example, the throughput of a level two node is inferior to the primary node). The replication status and replication delay can be recovered by the replsetgetstatus command.Log overviewAs part of all deployments, you should monitor the application and database logs to discover errors and view additional system information. It is important to associate the logs of the application with the database in order t

How can we achieve this visual display? We

change the library-level lock to a document-level lock. Performance issues caused by library-level locks should be expected to be significantly improved. Scenario Four: Micro-shardingThe definition of a differentiator is the use of MongoDB's Shard technology, but multiple or all Shard Mongod run on the same server (the server can be a physical or virtual machine). Because of the existence of library-level locks and the fact that
