-----------------------------------
Summary: Tsfiles in sequence space may be overlap with each other
due to LastFlushTime bug
Key: IOTDB-6095
URL: https://issues.apache.org/jira/browse/IOTDB-6095
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Jinrui Zhang
Assignee: Jinrui Zhang
Fix For: 1.2.1
This issue may lead to overlapped TsFile in sequence space.
For example,
When recover the last flush time map from two sequence TsFiles.
* TsFile A only contains device1 with end time = 10000
* TsFile B only contains device2 with end time = 9999
And the resources of these two TsFiles have been downgrade to FileTimeIndex.
The previous code will use TsFile B with end time = 9999 to recover the last
flush time of device1, which would cause sequence files overlapped.
It is due to the recover step bug during the maintenance of LastFlushTime
