AMS

Active Memory Sharing, is a virtualization technology that allows multiple partitions to share a pool of physical memory. This is designed to increase system memory utilization, thereby enabling you to realize a cost benefit by reducing the amount of physical memory required.

AMS是一个重要的组成部分,它负责管理数据库中的内存使用。AMS层负责在Greenplum的不同组件之间分配和回收内存,以确保系统的性能和稳定性。

matview

materialized view

mkdtemp

FTS

Fault Tolerance Serve,是GreenPlum中的故障检测服务,是保证GP高可用的核心功能。GreenPlum的Segment的健康检测及HA是由GP Master实现的,GP Master上面有个专门的进程–FTS进程,它可以快速检测到Primary或者Mirror是否挂掉,并及时作出Primary/Mirror 故障切换。如果FTS挂掉了,Master将会重新fork出来一个FTS进程。
