    • ALLOW_UNAVAILABLE

      public static final String ALLOW_UNAVAILABLE
      Should the virtual graph or data source be allowed to be created if it will be immediately unavailable? This is primarily used for internal testing of unavailable VGs and DSs but can be expanded later if we wish to make this status changeable by users at runtime.
      See Also:

    • FORCE_UNAVAILABLE

      public static final String FORCE_UNAVAILABLE
      Allows a test to cause a VG or DS to load as an unavailable graph or data source.

    • VG_RESULT_BATCH_SIZE

      public static final String VG_RESULT_BATCH_SIZE
      When a VG is executed asynchronously, the results are pushed to the main query thread in batches. This property defines the batch size.
      See Also:

    • PLAN_AREA_LIMIT

      public static final String PLAN_AREA_LIMIT
      Guards against combinatorial explosion of the query plan during optimization. Planning is aborted when the plan's "area" exceeds this limit. The current measure of area is the number of relational operators in the plan times the number of function calls in its expressions, but the measure may change in the future. A value less than or equal to zero disables the check.
