  +| *Description*               |	Enables {project-name} to leverage the HBase small scanner optimization. This optimization reduces I/O usage up to 66%
   and enables non-blocking reads for higher concurrency support. When a scan is known to require less than a HBASE BLOCK SIZE (default is 64K),
   then enabling the HBase small scanner optimization increases performance.
   | *Values*                    |

  | *Description*               | Allows index maintenance to be performed concurrently with base table operation. 
  | *Values*                    | *'ON'* Index maintenance is allowed. +
  *'OFF'* Index maintenance is not allowed. +
   +
  The default value is *'ON'*.
  | *Usage*                     | HBase `put` operations are blocking. When the table has one or more indexes, 
  then the insert/update/delete (IUD) operation response time is improved by executing the index maintenance 
  operations concurrently with the base table operation: the put operations to these HBase tables are executed 
  in different threads.
  | *Production Usage*          | Yes.  It is 'ON' by default. This feature can be disabled by setting this CQD to 'OFF'.
  | *Impact*                    | IUD operations on tables with one or more indexes can become slower.

  | *Description*               |	Allows a CQD specification to override the env settings for STFS locations.
  | *Values*                    | Scratch disk locations for overflow (linux path names).
  | *Usage*                     | Currently the scratch directory locations are set at installation time. The STFS layer that manages the scratch file creation reads the envvar in ms.env to determine where to create the scratch files.
  
  The CQD is allowed to be specified that will override the envvar setting. This will give the user some flexibility to change scratch directory locations.
  
  If the CQD is not set (empty), the envvar setting will work.
  
  The requirement is that the directories MUST exists on every node and Trafodion user will need permissions to write to those directories. If not, an error will be returned when a query involving sort/hash overflow is executed.
  
  | *Production Usage*          | Please contact {project-support}.
  | *Impact*                    | More volume of data can be processed, for example, large data set.
  | *Level*                     | System.
  | *Conflicts/Synergies*       | Not applicable.
  | *Real Problem Addressed*    | Not applicable.
  | *Introduced In Release*     | Trafodion 2.1.
  | *Deprecated In Release*     | Not applicable.
