 ### Directory Configuration
 ####################

 # system dir
 # If this property is unset, system will save the data in the default relative path directory under the IoTDB folder(i.e., %IOTDB_HOME%/data/datanode/system).
 # If it is absolute, system will save the data in exact location it points to.
 # If it is relative, system will save the data in the relative path directory it indicates under the IoTDB folder.
 # For windows platform
 # If its prefix is a drive specifier followed by "\\", or if its prefix is "\\\\", then the path is absolute. Otherwise, it is relative.
 # dn_system_dir=data\\datanode\\system
 # For Linux platform
 # If its prefix is "/", then the path is absolute. Otherwise, it is relative.
 # dn_system_dir=data/datanode/system


 # data dirs
 # If this property is unset, system will save the data in the default relative path directory under the IoTDB folder(i.e., %IOTDB_HOME%/data/datanode/data).
 # If it is absolute, system will save the data in exact location it points to.
 # If it is relative, system will save the data in the relative path directory it indicates under the IoTDB folder.
 # If there are more than one directory, please separate them by commas ",".
 # Note: If data_dirs is assigned an empty string(i.e.,zero-size), it will be handled as a relative path.
 # For windows platform
 # If its prefix is a drive specifier followed by "\\", or if its prefix is "\\\\", then the path is absolute. Otherwise, it is relative.

 # multi_dir_strategy
 # The strategy is used to choose a directory from data_dirs for the system to store a new tsfile.
 # System provides four strategies to choose from, or user can create his own strategy by extending org.apache.iotdb.db.conf.directories.strategy.DirectoryStrategy.
 # The info of the four strategies are as follows:
 # 1. SequenceStrategy: the system will choose the directory in sequence.
 # 2. MaxDiskUsableSpaceFirstStrategy: the system will choose the directory whose disk has the maximum space.
 # 3. MinFolderOccupiedSpaceFirstStrategy: the system will choose the directory whose folder has the minimum occupied space.
 # 4. RandomOnDiskUsableSpaceStrategy: the system will randomly choose the directory based on usable space of disks. The more usable space, the greater the chance of being chosen;
 # Set SequenceStrategy,MaxDiskUsableSpaceFirstStrategy and MinFolderOccupiedSpaceFirstStrategy to apply the corresponding strategy.
 # If this property is unset, system will use MaxDiskUsableSpaceFirstStrategy as default strategy.
 # For this property, fully-qualified class name (include package name) and simple class name are both acceptable.
 # dn_multi_dir_strategy=MaxDiskUsableSpaceFirstStrategy

 # consensus dir
 # If this property is unset, system will save the data in the default relative path directory under the IoTDB folder(i.e., %IOTDB_HOME%/data/datanode).
 # If it is absolute, system will save the data in the exact location it points to.
 # If it is relative, system will save the data in the relative path directory it indicates under the IoTDB folder.
 # Note: If consensus_dir is assigned an empty string(i.e.,zero-size), it will be handled as a relative path.

 # If its prefix is a drive specifier followed by "\\", or if its prefix is "\\\\", then the path is absolute. Otherwise, it is relative.
 # dn_consensus_dir=data\\datanode\\consensus
 # For Linux platform
 # If its prefix is "/", then the path is absolute. Otherwise, it is relative.
