TDengine通过查询函数向用户提供毫秒级的数据获取能力。直接将最近到达的数据保存在缓存中，可以更加快速地响应用户针对最近一条或一批数据的查询分析，整体上提供更快的数据库查询响应能力。从这个意义上来说，**可通过设置合适的配置参数将TDengine作为数据缓存来使用，而不需要再部署Redis或其他额外的缓存系统**，可有效地简化系统架构，降低运维的成本。需要注意的是，TDengine重启以后系统的缓存将被清空，之前缓存的数据均会被批量写入磁盘，缓存的数据将不会像专门的Key-value缓存系统再将之前缓存的数据重新加载到缓存中。 TDengine通过查询函数向用户提供毫秒级的数据获取能力。直接将最近到达的数据保存在缓存中，可以更加快速地响应用户针对最近一条或一批数据的查询分析，整体上提供更快的数据库查询响应能力。从这个意义上来说，**可通过设置合适的配置参数将TDengine作为数据缓存来使用，而不需要再部署Redis或其他额外的缓存系统**，可有效地简化系统架构，降低运维的成本。需要注意的是，TDengine重启以后系统的缓存将被清空，之前缓存的数据均会被批量写入磁盘，缓存的数据将不会像专门的Key-value缓存系统再将之前缓存的数据重新加载到缓存中。
每个vnode有自己独立的内存，而且由多个固定大小的内存块组成，不同vnode之间完全隔离。数据写入时，类似于日志的写法，数据被顺序追加写入内存，但每个vnode维护有自己的skip list，便于迅速查找。当一半以上的内存块写满时，启动落盘操作，而且后续写的操作在新的内存块进行。这样，一个vnode里有一半内存块是保留有最近的数据的，以达到缓存、快速查找的目的。一个vnode的内存块的个数由配置参数blocks决定，内存块的大小由配置参数cache决定。 每个vnode有自己独立的内存，而且由多个固定大小的内存块组成，不同vnode之间完全隔离。数据写入时，类似于日志的写法，数据被顺序追加写入内存，但每个vnode维护有自己的skip list，便于迅速查找。当三分之一以上的内存块写满时，启动落盘操作，而且后续写的操作在新的内存块进行。这样，一个vnode里有三分之一内存块是保留有最近的数据的，以达到缓存、快速查找的目的。一个vnode的内存块的个数由配置参数blocks决定，内存块的大小由配置参数cache决定。
### 持久化存储 ### 持久化存储
TDengine采用数据驱动的方式让缓存中的数据写入硬盘进行持久化存储。当vnode中缓存的数据达到一定规模时，为了不阻塞后续数据的写入，TDengine也会拉起落盘线程将缓存的数据写入持久化存储。TDengine在数据落盘时会打开新的数据库日志文件，在落盘成功后则会删除老的数据库日志文件，避免日志文件无限制的增长。 TDengine采用数据驱动的方式让缓存中的数据写入硬盘进行持久化存储。当vnode中缓存的数据达到一定规模时，为了不阻塞后续数据的写入，TDengine也会拉起落盘线程将缓存的数据写入持久化存储。TDengine在数据落盘时会打开新的数据库日志文件，在落盘成功后则会删除老的数据库日志文件，避免日志文件无限制的增长。
