dbms.security.auth_enabled=false
允許更新
dbms.allow_upgrade=true
初始Java堆大小
dbms.memory.heap.initial_size=512m
最大Java堆大小
dbms.memory.heap.max_size=512m
jvm額外啟動參數，多個配置多個
dbms.jvm.additional=-XX:MaxDirectMemorySize=512m

是否允許在線備份
dbms.backup.enabled=true
默認只能localhost備份
dbms.backup.listen_address=0.0.0.0:6362
#The maximum time interval of a transaction within which it should be completed.
dbms.transaction.timeout
Defines whether memory for transaction state should be allocated on- or offheap.ON_HEAP, OFF_HEAP。默認OFF_HEAP
