--------------------------
Summary: Accelerate the compaction of nonOverlap points in overlap
pages
Key: IOTDB-5130
URL: https://issues.apache.org/jira/browse/IOTDB-5130
Project: Apache IoTDB
Issue Type: Improvement
Reporter: 周沛辰
Assignee: 周沛辰
In the fast compaction, the overlapping pages will be put into the
pointPriorityReader, and the points are spit out in order. Every time a point
is spit out, an element must be popped out from the priority queue, and then
added into the queue. When the points do not overlap, it will cause a lot of
invalid heap sort, which will reduce the compaction rate. For example: there
are two pages, the time ranges are 1-500, 400-900, the actual overlapping part
is only 400-500, and the rest of the points can be spit out directly, instead
of adding into the queue and popping them out every time.
