MongoDB 1.6.1 has released enhanced dynamic expansion capabilities

MongoDB released the 1.6.0 version, which is the fourth major stable version of the 1.0,1.2,1.4 version, and released the 1.6.1 release on August 17.

This release focuses on enhanced dynamic expansion (Scale-out) features, http://www.aliyun.com/zixun/aggregation/14273.html ">sharding functionality is already available in the production environment." The use of horizontal partitioning and replication sets (replica sets) can be used to establish a parallel expansion of the data storage cluster, can achieve dynamic expansion of the cluster scale, and there is no single point of failure. As with other storage systems that support distributed clusters, the downtime of some machines and the increase or decrease of machines do not affect service. A single MongoDB program can be upgraded to a distributed cluster without shutting down if needed.

The replication collection (replica sets) allows you to create a highly stable cluster that provides automatic remediation (automatic fail over) and resiliency, and suggests that the original pair replication (replica pair) schema consumer be transferred to the replication collection schema when it is convenient.
