Develop
CnosDB can use common development languages such as Go, Rust, Java, Python to operate, and also supports ODBC, Arrow Flight SQL and other technologies. This chapter introduces how to connect CnosDB to read and write operations in the development process and provides some examples.
đī¸ Connect to CnosDB

đī¸ Query Data
CnosDB supports a variety of query access methods, some examples are provided below.Contains common programming languages such as Java, Python, Rust, Golang, C++
đī¸ Automatic Downsampling
The data write cycle is generally based on the actual table write frequency, which is usually related to the device that collects the data, sometimes it may need to process a large number of data points per second, and processing so much data for a long time may cause storage problems.A more natural solution would be to lower data samples.A more natural solution would be to lower data samples.
