   If OOM, two ways:
   (1) config manually if you use 0.10 or earlier version:
   
    conf/iotdb-engine.properties:
    enable_parameter_adapter=false
    tsfile_size_threshold=100000000
    memtable_size_threshold=JVM memory/2/storage group number/4
   
   (2) upgrade to version 0.11.2 or a later version
   Generally, in 0.11 version, you do not need to config manually. If still OOM, you could still try to config
   
    conf/iotdb-engine.properties:
    enable_mem_control=false
    tsfile_size_threshold=100000000
    memtable_size_threshold=JVM memory/2/storage group number/4
   
    If still OOM, lower the memtable_size_threshold!
   
   (3) check whether you have millions of devices, the penultimate nodes in the path. Try to modify your model to less than one million devices.
