----------------------------------
Summary: Change the keys of memtable to a Tree structure
Key: IOTDB-4474
URL: https://issues.apache.org/jira/browse/IOTDB-4474
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Jialin Qiao
Investigate if changing the keys to a tree structure could bring some benefits.
(1) For deleting data, users give a pattern, we could use prefix node match,
instead of match each key.
(2) Compress key for saving memory.
This may impact the write performance, and need some experiments.
