the router process that the MongoDB is equipped with. It routes all requests and then aggregates the results. It does not itself store data or configuration information but caches information about the configuration server. C. Configuring the server configuration server stores the configuration information for the cluster: data and slice correspondence. MONGOs does not store data permanently, so it needs a place to store the configuration of the Shard. It gets the synchronization data from

mongodump.exe backup is to get the current server snapshot through a query and write the snapshot into the disk. Therefore, this method is not saved in real time, because after obtaining the snapshot, the server also has data writing. To ensure backup security, we can also use the fsync lock to temporarily write server data into the cache. Backup command: ...

CopyMongoDB replication is important, especially now that the storage engine does not support click Persistence. Not only can replication be used to deal with failover, data integration, but also read extensions, hot backups, or data sources as offline batches. 1. master-Slave copyingMaster-slave replication is the most common way of MongoDB replication. Can be used for backup, failover, read extension, and more.The basic is to build a master node and one or more from nodes, each from the node

du can see the changes in the cluster in real time through the rs.status () command. Sharding Similar to replica set, a quorum node is required, but sharding also needs to configure nodes and routing nodes. This is the most complex of the three ways to build a cluster.

It is recommended to have primary members use larger oplog to save enough log of operations. Iv. Creating a configuration document 1.

A cluster consists of the following three services: Shards server: each shard is composed of one or more mongod processes used to store data. Config server: used to store the metadata information of a cluster, including the information of each shard and chunks. Route server: used to provide the routing service, connected by the client, so that the entire cluster looks like a single DB Server In addition, chunks are continuous data blocks in Mongo
