Hi all, I've completed a design draft for supporting swinging door compression.
Jira: jira SDT link <https://issues.apache.org/jira/browse/IOTDB-890?filter=-4&jql=assignee%20in%20(haimeiguo)%20order%20by%20created%20DESC> design doc: SDT design doc link <https://docs.google.com/document/d/1VeTwVsm4CkQSVR65bWw9pKg6gRdiDYUz0lBBhWXHl5A/edit?usp=sharing> The doc explains SDT algorithm, compression and decompression process, performance tests and SDT + IoTDB implementation and usage. There is still some question about where to use this algorithm. If you have any idea, welcome to comment. Thank you! Haimei Guo
