Hi folks, Very happy to see the great achievements of IoTDB in the past year! Congratulate!
With the advent of the 5G era, IoT will definitely set off a new wave, and it will also be the era of IoTDB's grand development. In 2020, I wish the IoTDB community a continuous state and grows, become a top level project of Apache as soon as possible! Happy new Chinese Year!
