# What is TDengine?
TDengine is an open source, cloud native time-series database optimized for Internet of Things (IoT), Connected Cars, and Industrial IoT. It enables efficient, real-time data ingestion, processing, and monitoring of TB and even PB scale data per day, generated by billions of sensors and data collectors. TDengine differentiates itself from other TSDBs with the following advantages.:

# Building
At the moment, TDengine server supports running on Linux, Windows, and macOS systems. You can choose to [install from packages](https://www.tdengine.com/getting-started/#Install-from-Package) or build it from the source code. This quick guide is for installation from the source only.

We provide a few useful tools such as taosBenchmark (was named taosdemo) and taosdump. They were part of TDengine. By default, TDengine compiling does not include taosTools. You can use 'cmake .. -DBUILD_TOOLS=true' to make them be compiled with TDengine.

根据元数据信息中的 End Point 信息,将查询请求序列化后发送到该表所在的数据节点(dnode)。dnode 接收到查询请求后,识别出该查询请求指向的虚拟节点(vnode),将消息转发到 vnode 的查询执行队列。vnode 的查询执行线程建立基础的查询执行环境,并立即返回该查询请求,同时开始执行该查询。
