), and manageability (manageability). The advantages of LVS are:1, anti-load capacity, is the work in the Network 4 layer only for distribution, No traffic generated , this feature also determines its performance in the Load Balancer software is the strongest, the memory and CPU resource consumption is low.2, the configuration is relatively low, this is a disadvantage is also an advantage, because there is not much to configure things, so do not need too much contact, greatly reducing the chance

Hbase.client.scanner.cachingDefines the number of rows retrieved when the next method is called in the scanner. The larger the number, the fewer remote calls the client needs to make to the regionserver at the time of the scan. The larger the value, the larger the client consumes memory.Hbase.balancer.periodThe region equalizer runs periodically in HBase master. This property defines the time interval at which the

The software proxy maintains an open connection to a series of servers. When a client accesses a server, it must go through the software agent, which can redirect a user's access to a server through some load balancing algorithms (such as a dnsround-robin, random method, Access tradeoff algorithm). This software agent method can detect the server panic or no response in time, and effectively avoid the failure access in the Dnsround-robin method. Hardware

Splitting is only a logical operation and does not affect the physical order of the documents in the Shard collection.Migration is managed by the software called the "balancer" equalizer, and its task is to ensure that the data remains evenly distributed across the nodes. This capability can be achieved by tracking the number of shard blocks. In general, when the number of shards in a cluster with the largest chunk of the block i
