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.
