--------------------------
Summary: Get the devices in batches while compacting
Key: IOTDB-4666
URL: https://issues.apache.org/jira/browse/IOTDB-4666
Project: Apache IoTDB
Issue Type: Improvement
Reporter: 周沛辰
Assignee: 周沛辰
At present, the system obtains all devices in the source file at one time when
compacting, which may cause OOM problems in the scenario of a large number of
devices.
To solve this problem, we should read the devices on one index tree node at a
time instead of reading all devices from files at one time.
