ElasticSearch 6.x 学习笔记：9.版本控制

9.1 冲突处理如果两个线程同时修改一个文档，这时就会发生冲突。比如某件商品存货100件，用户1下单买走1件，剩余99件；与此同时用户2也下单买走1件，但是用户2不知道用户1已经下单，看到剩余商品仍然是99件。这样造成系统中显示商品总数比实际数量要多，这种情况在商业系统中肯定是不能容忍的。在数据库领域中，有两种方法通常被用来确保并发更新时变更不会丢失： 1、悲观并发控制这种方法被关系型数据...

5.1 索引索引(index)是ElasticSearch存放具体数据的地方，是一类具有相似特征的文档的集合。ElasticSearch中索引的概念具有不同意思，这里的索引相当于关系数据库中的一个数据库实例。在ElasticSearch中索引还可以作为动词，表示对数据进行索引操作。5.2 类型在一个ElasticSearch索引中，可以有多个类型。一个类型是索引的一个逻辑上的分类，通常具有一组相同字...
