I. Collection1. A logical index consisting of multiple cores is called a collection. A collection is essentially an index that can span multiple cores, with redundant indexes. 2.collection consists of different shard, each shard multiple replica, each shard has a leadereplica, each replica is a physical index, so a replica corresponds to a core two. The differenc

First, the principle of work 1. The MongoDB 2.6 version starts with the recommended replica set, which is no longer recommended for master-slave replication. 2. The replica set requires at least 3, can be 3 copies of all the replica set, you can also let one of them do the quorum. 3. Only 1 hosts in the replica set can

The frame diagram is as follows:Among them, the electors do not participate in the data storage, its role is only to elect a new master. When the original master is restored, he will only be adde

Complete example of building a MongoDB cluster (replica set + Shard) ...Prepare four machines, namely BLUEJOE1,BLUEJOE2,BLUEJOE3, and BLUEJOE0The replica set and Shard policy are determined as follows: 3 replica sets will be created, named Shard1,shard2,shard3; The above 3 replica sets as 3 shards; Eac

Label: As I said earlier, the MongoDB database supports data replication between servers. Support for replication between master-slave mode and server. The goal of course is to achieve load balancing and failure recovery. There are two techniques built into the MONGO: master-slave copy, replica set. The configuration of these two modes is briefly described below. First, master-slave replication Master-slave replication is a simple database synchrono

Tags: opera copy asynchronous admin Leo Download index case ptimeIntroducedReplication set (Replica sets) is a master/slave replication mechanism for asynchronous synchronization of the same data, so that multiple machines have more than one copy of the same data, due to the automatic failover and recovery features, When the main library is down and no user intervention is required to automatically switch to the master library on other backup servers,
