class InterpolateOperator extends BaseGenericOperator[StreamOperatorInfo, DataFrame]

:: ApplicationDeveloperApi ::

Operator that converts the dataframe at regular intervals by interpolation. LINEAR: curve fitting using linear polynomials to construct new data points. NEAREST: Nearest-neighbor interpolation, selects the value of the nearest point. PREV_COPY: selects the previous value.

    o

    Object that contains message ksb.csle.common.proto.StreamOperatorProto.InterpolationInfo InterpolationInfo contains attributes as follows:

    • indexColumnName: Column name of index column (required)
    • stepSize: Intervals of index range (required)
    • methodOption: Interpolation method. Enum(LINEAR, NEAREST, PREV_COPY) (required)
    • keepColumnType: Parameter to define whether to keep the original column type (optional) After interpolation option, the column type is changed to double type.

    InterpolationInfo

    message InterpolationInfo {
    required string indexColumnName = 1;
    required int32 stepSize = 2 [default = 1];
    required InterpolationMethodOption methodOption = 3 [default = LINEAR];
    optional bool keepColumnType = 4 [default = false];
