Tian Jiang created IOTDB-143: -------------------------------- 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 featureĀ 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. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
