二级索引存储

使用场景介绍全局二级索引是表格存储提供的一个新特性。当用户创建一张表时，其所有PK列构成了该表的“一级索引”：即给定完整PK，可以迅速的查找到该PK所在行的数据。但是越来越多的业务场景中，需要对表的属性列，或者非首列PK进行条件...

表格存储TableStore提供海量半结构化数据写入和存储的能力，大...Global Index是表格存储研发的二级索引功能，索引表能够根据指定的属性列或者属性列的组合来组织，提供了根据属性列高效查询的能力，满足多维度查询的需求.互联网行业开发者.

主表和二级索引在memtable中如何存储

假设有主表emp(empid,empname,empdep)，其中empid是主键，这时我对empname创建一个idx_name(empname)二级索引，OB是将此当作一个表来处理吗？如果是的话，这个“索引表”在内存中也会有一个memtable吗？问题较多，感谢感谢。
