    o

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

    • columName: column name (required)
    • dataType: column data type (required)
    • more: additional schemes that change column data type (repeated)

    ChangeColumnDataTypeInfo

    message ChangeColumnDataTypeInfo {
      required string columName = 1;
      required FieldType dataType = 2;
      repeated ChangeParam more = 3;
