  • Field Details

    • SEARCH_COST_REVERT

      static final int SEARCH_COST_REVERT
      Elementary search cost using a revert index.
      See Also:

    • SEARCH_COST_REVERT_MULTIPLE

      static final int SEARCH_COST_REVERT_MULTIPLE
      Elementary search cost using multiple time the same revert index.
      See Also:

    • ALL_PARTITION_MATCH_COST

      static final int ALL_PARTITION_MATCH_COST
      Elementary cost of return all rows of a partition.

      This is a very expensive operation since it matches all rows of a partition so it creates a large result and should always be performed after a regular scan.

      See Also:

    • SEARCH_COST_SCAN_PRIMITIVE

      static final int SEARCH_COST_SCAN_PRIMITIVE
      Elementary search cost for full-scan of primitive data.
      See Also:

    • SEARCH_COST_SCAN_OBJECT

      static final int SEARCH_COST_SCAN_OBJECT
      Elementary search cost for full-scan of object data.
      See Also:

    • SEARCH_COST_SCAN_CONDITION

      static final int SEARCH_COST_SCAN_CONDITION
      Elementary search cost for full-scan of object data with a condition.
      See Also:

    • SEARCH_COST_CHECK_CONDITION

      static final int SEARCH_COST_CHECK_CONDITION
      Elementary search cost for full-scan of object data.
      See Also:

    • SEARCH_COST_SCAN_SWAPPED_PRIMITIVE

      static final int SEARCH_COST_SCAN_SWAPPED_PRIMITIVE
      Elementary search cost for full-scan of swapped object data.
      See Also:

    • SEARCH_COST_SCAN_SWAPPED_OBJECT

      static final int SEARCH_COST_SCAN_SWAPPED_OBJECT
      Elementary search cost for full-scan of swapped object data.
      See Also:

    • SEARCH_EFFICIENCY_DEFAULT

      static final int SEARCH_EFFICIENCY_DEFAULT
      Default search efficiency, also applied when efficiency cannot be predicted.
