• RedoBuffer : Number of bytes on each data node allocated for writing redo logs. 

• RedoOverCommitCounter : When RedoOverCommitLimit has been exceeded this many times, transactions are aborted, and operations are handled as specified by DefaultOperationRedoProblemAction. 

• RedoOverCommitLimit : Each time that flushing current redo buffer takes longer than this many seconds, number of times that this has happened is compared to RedoOverCommitCounter. 

• ReservedConcurrentIndexOperations : Number of simultaneous index operations having dedicated resources on one data node. 

• ReservedConcurrentOperations : Number of simultaneous operations having dedicated resources in transaction coordinators on one data node. 

• ReservedConcurrentScans : Number of simultaneous scans having dedicated resources on one data node. 

• ReservedConcurrentTransactions : Number of simultaneous transactions having dedicated resources on one data node. 

• ReservedFiredTriggers : Number of triggers having dedicated resources on one data node. 

• ReservedLocalScans : Number of simultaneous fragment scans having dedicated resources on one data node. 

• ReservedTransactionBufferMemory : Dynamic buffer space (in bytes) for key and attribute data allocated to each data node. 

• RestartOnErrorInsert : Control type of restart caused by inserting error (when StopOnError is enabled). 

• SchedulerExecutionTimer : Number of microseconds to execute in scheduler before sending. 

• SchedulerResponsiveness : Set NDB scheduler response optimization 0-10; higher values provide better response time but lower throughput. 

• SchedulerSpinTimer : Number of microseconds to execute in scheduler before sleeping. 

• ServerPort : Port used to set up transporter for incoming connections from API nodes. 

• SharedGlobalMemory : Total number of bytes on each data node allocated for any use. 

• SpinMethod : Determines spin method used by data node; see documentation for details. 

• StartFailRetryDelay : Delay in seconds after start failure prior to retry; requires StopOnError = 0. 

• StartFailureTimeout : Milliseconds to wait before terminating. (0=Wait forever). 

• StartNoNodeGroupTimeout : Time to wait for nodes without nodegroup before trying to start (0=forever). 

• StartPartialTimeout : Milliseconds to wait before trying to start without all nodes. (0=Wait forever). 

• StartPartitionedTimeout : Milliseconds to wait before trying to start partitioned. (0=Wait forever). 

• StartupStatusReportFrequency : Frequency of status reports during startup. 

• StopOnError : When set to 0, data node automatically restarts and recovers following node failures.
