ConfigNode Configuration

IoTDB ConfigNode files are under conf.

  • confignode-env.sh/bat：Environment configurations, in which we could set the memory allocation of ConfigNode.

  • iotdb-confignode.properties：IoTDB ConfigNode system configurations.

Environment Configuration File（confignode-env.sh/bat）ConfigNode Config Manual - 图1open in new window

The environment configuration file is mainly used to configure the Java environment related parameters when ConfigNode is running, such as JVM related configuration. This part of the configuration is passed to the JVM when the ConfigNode starts.

The details of each parameter are as follows:

  • MAX_HEAP_SIZE
NameMAX_HEAP_SIZE
DescriptionThe maximum heap memory size that IoTDB can use
TypeString
DefaultOn Linux or MacOS, the default is one quarter of the memory. On Windows, the default value for 32-bit systems is 512M, and the default for 64-bit systems is 2G.
EffectiveAfter restarting system
  • HEAP_NEWSIZE
NameHEAP_NEWSIZE
DescriptionThe minimum heap memory size that IoTDB will use when startup
TypeString
DefaultOn Linux or MacOS, the default is min{cores * 100M, one quarter of MAX_HEAP_SIZE}. On Windows, the default value for 32-bit systems is 512M, and the default for 64-bit systems is 2G.

  • MAX_DIRECT_MEMORY_SIZE
NameMAX_DIRECT_MEMORY_SIZE
DescriptionThe max direct memory that IoTDB could use
TypeString
DefaultEqual to the MAX_HEAP_SIZE
