        * If this option is set to TRUE, then high.cardinality.identify.enable property will be disabled during data load.
        
    +- **SORT_SCOPE:** This property can have four possible values :
    +
    +    * BATCH_SORT : The sorting scope is smaller and more index tree will be created,thus loading is faster but query maybe slower.
    +
    +    * LOCAL_SORT : The sorting scope is bigger and one index tree per data node will be created, thus loading is slower but query is faster.
    +
    +    * GLOBAL_SORT : The sorting scope is bigger and one index tree per task will be created, thus loading is slower but query is faster.
    +
    +    * NO_SORT     : Feasible if we want to load our data in unsorted manner.

    +    For BATCH_SORT:
    +
    +    ```
    +    OPTIONS ('SORT_SCOPE'='BATCH_SORT')

    +    Note :
    +
    +    * batch_sort_size_inmb : Size of data in MB to be processed in batch. By default it is the 45 percent size of sort.inmemory.size.inmb(Memory size in MB available for in-memory sort).
