3BSE013234R1开发组是否具有数据库分库经历；因为要在出产环境中分区，因而要考虑分区给出产环境带来的影响。
三、数据冷热别离在学数据冷热别离前咱们先来看一下底子概3.1 底子概念冷热数据：所谓的冷数据指的是不常用的，状况底子不变的数据，热数据指的是常常运用，而且会对其进行操作的数据。冷热库：存放冷数据的数据库被称为冷库，存放热数据的数据库被称为热库
冷热别离：在处理数据时，将数据依照冷热分为冷库和热库，在咱们的事例中工单表是热库。冷热别离计划冷热别离计划有两种，一种是冷热数据都运用同一种类型的数据库，另一种是将冷数据存储在NoSQL数据库中。下面们我来别离阐明一下。
The switchgear also features a "higher level" safety design with a fully insulated design that ensures the safety of all live parts and uses 92 percent fewer busbar components and 90 percent fewer electrical connections than conventional switchgear. On the basis of reducing the cost and improving the efficiency of operation and maintenance, switch equipment is more secure, becoming the ideal choice for power, food and beverage, data center and other industries. In addition, iVD4® medium voltage intelligent solution also appeared in the exhibition, which realizes the deep integration of VD4 vacuum circuit breaker with sensors and monitoring units. The integrated solution is out-of-the-box, helping customers more smoothly and intuitively realize the status perception of switching equipment. The accurate evaluation system provides targeted operation and maintenance suggestions. To bring customers better quality, more reliable, more secure intelligent power distribution operation and management experience. High current type
