--------------------------------
Summary: Support merge
Key: IOTDB-143
URL: https://issues.apache.org/jira/browse/IOTDB-143
Project: Apache IoTDB
Issue Type: New Feature
Reporter: Tian Jiang
Merge (or compaction) is an important feature of LSM or LSM-like systems and
IoTDB depends on it to put the data in the sequential files and unsequential
files together and make them ordered and non-duplicated again.
Merged data files provide better locality and potentially higher compression
rate (for some of the missing values are supplemented). While merging interacts
with many aspects of IoTDB like ingestion and query, finding an effective
implementation may be rather difficult.
