This chapter introduces how to get data out of TDengine cloud service. Besides normal query using SQL, users can use data subscription which is provided by the message queue component inside TDengine to access the data stored in TDengine. TDengine provides connectors for application programmers to access the data stored in TDengine. TDengine also provides some tools, like taosdump, which is a tool provided by TDengine to dump the data stored in TDengine cloud service into files, and
taosX, which is another tool to sync up the data in one TDengine cloud service into another. Furthermore, 3rd party tools, like prometheus, can also be used to write data into TDengine.
