[GitHub] [iotdb] qiaojialin opened a new issue #2611: An unsequence file that covers too many sequence file causes OOM query

qiaojialin opened a new issue #2611:
URL: https://github.com/apache/iotdb/issues/2611


   Due to the separation of sequence and unsequenced data, the unsequenced file may cover a long time range, which overlaps too many sequence files.
   
   For example, 
   the time range of sequence file is [1,10], [13,20], [21,30], [31,40],..., [1000,1010]
   unsequence file is [12, 1000].
   
   If we query [11, 1000], the unsequence file is the first file in the query range, and we read all its overlapped Chunks into memory. Then OOM occurs.
