• CrashOnCorruptedTuple : When enabled, forces node to shut down whenever it detects corrupted tuple. 

• DataDir : Data directory for this node. 

• DataMemory : Number of bytes on each data node allocated for storing data; subject to available system RAM and size of IndexMemory. 

• DefaultHashMapSize : Set size (in buckets) to use for table hash maps. Three values are supported: 0, 240, and 3840.. 

• DictTrace : Enable DBDICT debugging; for NDB development. 

• DiskDataUsingSameDisk : Set to false if Disk Data tablespaces are located on separate physical disks. 

• DiskIOThreadPool : Number of unbound threads for file access, applies to disk data only. 

• Diskless : Run without using disk. 

• DiskPageBufferEntries : Memory to allocate in DiskPageBufferMemory; very large disk transactions may require increasing this value. 

• DiskPageBufferMemory : Number of bytes on each data node allocated for disk page buffer cache. 

• DiskSyncSize : Amount of data written to file before synch is forced. 

• EnablePartialLcp : Enable partial LCP (true); if this is disabled (false), all LCPs write full checkpoints. 

• EnableRedoControl : Enable adaptive checkpointing speed for controlling redo log usage. 

• EventLogBufferSize : Size of circular buffer for NDB log events within data nodes. 

• ExecuteOnComputer : String referencing earlier defined COMPUTER. 

• ExtraSendBufferMemory : Memory to use for send buffers in addition to any allocated by TotalSendBufferMemory or SendBufferMemory. Default (0) allows up to 16MB. 

• FileSystemPath : Path to directory where data node stores its data (directory must exist). 

• FileSystemPathDataFiles : Path to directory where data node stores its Disk Data files. Default value is FilesystemPathDD, if set; otherwise, FilesystemPath is used if it is set; otherwise, value of DataDir is used. 

• FileSystemPathDD : Path to directory where data node stores its Disk Data and undo files. Default value is FileSystemPath, if set; otherwise, value of DataDir is used. 

• FileSystemPathUndoFiles : Path to directory where data node stores its undo files for Disk Data. Default value is FilesystemPathDD, if set; otherwise, FilesystemPath is used if it is set; otherwise, value of DataDir is used. 

• FragmentLogFileSize : Size of each redo log file. 

• HeartbeatIntervalDbApi : Time between API node-data node heartbeats. (API connection closed after 3 missed heartbeats). 

• HeartbeatIntervalDbDb : Time between data node-to-data node heartbeats; data node considered dead after 3 missed heartbeats.
