What is New in NDB Cluster BIGINT ; the allowed range of the offset value is the same as the signed version of that type (this allows the offset to be negative if desired). The new option can be used multiple times in the same invocation of  ndb_restore , so that you can remap to new values multiple columns of the same table, different tables, or both. The offset value does not have to be the same for all instances of the option. In addition, two new options are provided for  ndb_desc , also beginning in NDB 8.0.21: For more information and examples, see the description of the  --remap-column  option. For fine-tuning spin behavior, it is also possible to set these and additional spin parameters directly, using the existing  SchedulerSpinTimer  data node configuration parameter as well as the following DUMP  commands in the  ndb_mgm  client: NDB 8.0.20 also adds a new TCP configuration parameter  TcpSpinTime  which sets the time to spin for a given TCP connection. For additional information, see the description of the  SpinMethod  parameter, the listed  DUMP commands, and Section 23.4.29, “ndb_top — View CPU usage information for NDB threads” . 3948 The  ndb_top  tool is also enhanced to provide spin time information per thread. • --auto-inc  (short form  -a ): Includes the the next auto-increment value in the output, if the table has an  AUTO_INCREMENT  column. • --context  (short form  -x ): Provides extra information about the table, including the schema, database name, table name, and internal ID. • Send thread improvements.   As of NDB 8.0.20, each send thread now handles sends to a subset of transporters, and each block thread now assists only one send thread, resulting in more send threads, and thus better performance and data node scalability. • Adaptive spin control using SpinMethod.   A simple interface for setting up adaptive CPU spin on platforms supporting it, using the  SpinMethod  data node parameter. This parameter (added in NDB 8.0.20, functional beginning with NDB 8.0.24) has four settings, one each for static spinning, cost-based adaptive spinning, latency-optimized adaptive spinning, and adaptive spinning optimized for database machines on which each thread has its own CPU. Each of these settings causes the data node to use a set of predetermined values for one or more spin parameters which enable adaptive spinning, set spin timing, and set spin overhead, as appropriate to a given scenario, thus obviating the need to set these directly for common use cases. • DUMP 104000 (SetSchedulerSpinTimerAll) : Sets spin time for all threads • DUMP 104001 (SetSchedulerSpinTimerThread) : Sets spin time for a specified thread • DUMP 104002 (SetAllowedSpinOverhead) : Sets spin overhead as the number of units of CPU time allowed to gain 1 unit of latency • DUMP 104003 (SetSpintimePerCall) : Sets the time for a call to spin • DUMP 104004 (EnableAdaptiveSpinning) : Enables or disables adpative spinning
