Write data

Last Updated: Jul 23, 2018

Note the following when writing data:

  • Do not write more than 50,000 points per second; otherwise batch writing fails. Write data in the “concurrent+batch” manner. The concurrency is recommended to be over 256, and the batch quantity over 400.
  • TSDB uses an algorithm similar to Nagle of TCP. If the quantity of points written in a second is small, a single TSDB starts writing data until the points add to 2000 or until the 200 ms time-out is reached. Therefore, with two sets of TSDB being used as the load, RT increases when less than 4000 points are written per second.
  • No more than 16 Tags can be written.
