      • DEFAULT_NULL_COLLATION

        public static final CalciteConnectionProperty DEFAULT_NULL_COLLATION
        How NULL values should be sorted if neither NULLS FIRST nor NULLS LAST are specified. The default, HIGH, sorts NULL values the same as Oracle.

      • DRUID_FETCH

        public static final CalciteConnectionProperty DRUID_FETCH
        How many rows the Druid adapter should fetch at a time when executing "select" queries.

      • QUOTED_CASING

        public static final CalciteConnectionProperty QUOTED_CASING

      • CASE_SENSITIVE

        public static final CalciteConnectionProperty CASE_SENSITIVE
        Whether identifiers are matched case-sensitively. If not specified, value from LEX is used.

      • SPARK

        public static final CalciteConnectionProperty SPARK
        Specifies whether Spark should be used as the engine for processing that cannot be pushed to the source system. If false (the default), Calcite generates code that implements the Enumerable interface.

      • TIME_ZONE

        public static final CalciteConnectionProperty TIME_ZONE
        Time zone, for example 'gmt-3'. Default is the JVM's time zone.

      • values

        public static CalciteConnectionProperty[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (CalciteConnectionProperty c : CalciteConnectionProperty.values())
