 * Creates a GPUdb API object for the specified URL using the given options.
 * Once created, all options are immutable; to use a different URL or change
 * options, create a new instance. (Creating a new instance does not
 * communicate with the server and should not cause performance concerns.)
 *
 * @class
 * @classdesc GPUdb API object that provides access to GPUdb server functions.
 * @param {String|String[]} url The URL of the GPUdb server (e.g.,
                   <code>http://hostname:9191</code>). May also be specified as
                   a list of urls; all urls in the list must be well formed.
 * @param {Object} [options] A set of configurable options for the GPUdb API.
 * @param {String} [options.username] The username to be used for authentication
 *                 to GPUdb. This username will be sent with every GPUdb request
 *                 made via the API along with the specified password and may be
 *                 used for authorization decisions by the server if it is so
 *                 configured. If neither username nor password is specified, no
 *                 authentication will be performed.
 * @param {String} [options.password] The password to be used for authentication
 *                 to GPUdb. This password will be sent with every GPUdb request
 *                 made via the API along with the specified username and may be
 *                 used for authorization decisions by the server if it is so
 *                 configured. If neither username nor password is specified, no
 *                 authentication will be performed.
 * @param {Number} [options.timeout] The timeout value, in milliseconds, after
 *                 which requests to GPUdb will be aborted. A timeout value of
 *                 zero is interpreted as an infinite timeout. Note that timeout
 *                 is not suppored for synchronous requests, which will not
 *                 return until a response is received and cannot be aborted.

 * <p>
 * Estimated cardinality is calculated by using the hyperloglog approximation

 * <p>
 * Percentiles and percentile ranks are approximate and are calculated using

 * 'percentile(75.0),percentile(99.0),percentile_rank(1234.56),percentile_rank(-5)').
 * <p>
 * A second, comma-separated value can be added to the <code>percentile</code>
 * statistic to calculate percentile resolution, e.g., a 50th percentile with
 * 200 resolution would be 'percentile(50,200)'.
 * <p>
 * The weighted average statistic requires a <code>weight_column_name</code> to
 * be specified in <code>options</code>. The weighted average is then defined
 * as the sum of the products of <code>column_name</code> times the

 * If a <code>result_table</code> name is specified in the
 * <code>options</code>, the results are stored in a new table with that
 * name--no results are returned in the response.  Both the table name and
 * resulting column name must adhere to <a
 * href="../../concepts/tables.html#table" target="_top">standard naming
 * conventions</a>; any column expression will need to be aliased.  If the
 * source table's <a href="../../concepts/tables.html#shard-keys"
 * target="_top">shard key</a> is used as the <code>column_name</code>, the
 * result table will be sharded, in all other cases it will be replicated.
 * Sorting will properly function only if the result table is replicated or if
 * there is only one processing node and should not be relied upon in other
 * cases.  Not available if <code>table_name</code> is a collection or when the
 * value of <code>column_name</code> is an unrestricted-length string.
 *
 * @param {String} table_name  Name of an existing table/collection on which
 *                             the operation will be performed.
 * @param {String} column_name  Name of the column or an expression containing
 *                              one or more column names on which the unique
 *                              function would be applied.
 * @param {Number} offset  A positive integer indicating the number of initial
 *                         results to skip (this can be useful for paging
 *                         through the results).
 * @param {Number} limit  A positive integer indicating the maximum number of
 *                        results to be returned. Or END_OF_SET (-9999) to
 *                        indicate that the max number of results should be
 *                        returned.

 *                             contains geospatial geometry objects in

 *                             the entire) <a
 *                             href="../../concepts/tables.html#primary-keys"

 *                                     <li> 'nullable': This property indicates
 *                             that this column is nullable.  However, setting
 *                             this property is insufficient for making the
 *                             column nullable.  The user must declare the type
 *                             of the column as a union between its regular
 *                             type and 'null' in the avro schema for the
 *                             record type in <code>type_definition</code>.
 *                             For example, if a column is of type integer and
 *                             is nullable, then the entry for the column in
 *                             the avro schema must be: ['int', 'null'].
 *                             The C++, C#, Java, and Python APIs have built-in
 *                             convenience for bypassing setting the avro
 *                             schema by hand.  For those languages, one can
 *                             use this property as usual and not have to worry
 *                             about the avro schema for the record.
 *                                     <li> 'dict': This property indicates
 *                             that this column should be dictionary encoded.
 *                             It can only be used in conjunction with string
 *                             columns marked with a charN or date property or
 *                             with int or long columns. This property is
 *                             appropriate for columns where the cardinality
 *                             (the number of unique values) is expected to be
 *                             low, and can save a large amount of memory.
 *                                     <li> 'init_with_now': For columns with
 *                             attributes of date, time, datetime or timestamp,
 *                             at insert time, replace empty strings and
 *                             invalid timestamps with NOW()
 *                             </ul>
 *                             The default value is an empty dict ( {} ).
 * @param {Object} options  Optional parameters.
 * @param {GPUdbCallback} callback  Callback that handles the response.  If not
 *                                  specified, request will be synchronous.

 *                          map of string to doubles, while most others are
 *                          maps of string to string.  In this map, the top
 *                          level keys represent which column's parameters are
 *                          being specified, while the internal keys represents
 *                          which parameter is being specified.  These
 *                          parameters take on different meanings depending on
 *                          the type of the column.  Below follows a more
 *                          detailed description of the map:
 *                          <ul>
 *                                  <li> 'seed': If provided, the internal
 *                          random number generator will be initialized with
 *                          the given value.  The minimum is 0.  This allows
 *                          for the same set of random numbers to be generated
 *                          across invocation of this endpoint in case the user
 *                          wants to repeat the test.  Since
 *                          <code>options</code>, is a map of maps, we need an
 *                          internal map to provide the seed value.  For
 *                          example, to pass 100 as the seed value through this
 *                          parameter, you need something equivalent to:
 *                          'options' = {'seed': { 'value': 100 } }
 *                          <ul>
 *                                  <li> 'value': Pass the seed value here.
 *                          </ul>
 *                                  <li> 'all': This key indicates that the
 *                          specifications relayed in the internal map are to
 *                          be applied to all columns of the records.
 *                          <ul>
 *                                  <li> 'min': For numerical columns, the
 *                          minimum of the generated values is set to this
 *                          value.  Default is -99999.  For point, shape, and
 *                          track columns, min for numeric 'x' and 'y' columns
 *                          needs to be within [-180, 180] and [-90, 90],
 *                          respectively. The default minimum possible values
 *                          for these columns in such cases are -180.0 and
 *                          -90.0. For the 'TIMESTAMP' column, the default
 *                          minimum corresponds to Jan 1, 2010.
 *                          For string columns, the minimum length of the
 *                          randomly generated strings is set to this value
 *                          (default is 0). If both minimum and maximum are
 *                          provided, minimum must be less than or equal to
 *                          max. Value needs to be within [0, 200].
 *                          If the min is outside the accepted ranges for
 *                          strings columns and 'x' and 'y' columns for
 *                          point/shape/track, then those parameters will not
 *                          be set; however, an error will not be thrown in
 *                          such a case. It is the responsibility of the user
 *                          to use the <code>all</code> parameter judiciously.
 *                                  <li> 'max': For numerical columns, the
 *                          maximum of the generated values is set to this
 *                          value. Default is 99999. For point, shape, and
 *                          track columns, max for numeric 'x' and 'y' columns
 *                          needs to be within [-180, 180] and [-90, 90],
 *                          respectively. The default minimum possible values
 *                          for these columns in such cases are 180.0 and 90.0.
 *                          For string columns, the maximum length of the
 *                          randomly generated strings is set to this value
 *                          (default is 200). If both minimum and maximum are
 *                          provided, *max* must be greater than or equal to
 *                          *min*. Value needs to be within [0, 200].
 *                          If the *max* is outside the accepted ranges for
 *                          strings columns and 'x' and 'y' columns for
 *                          point/shape/track, then those parameters will not
 *                          be set; however, an error will not be thrown in
 *                          such a case. It is the responsibility of the user
 *                          to use the <code>all</code> parameter judiciously.
 *                                  <li> 'interval': If specified, generate
 *                          values for all columns evenly spaced with the given
 *                          interval value. If a max value is specified for a
 *                          given column the data is randomly generated between
 *                          min and max and decimated down to the interval. If
 *                          no max is provided the data is linerally generated
 *                          starting at the minimum value (instead of
 *                          generating random data). For non-decimated
 *                          string-type columns the interval value is ignored.
 *                          Instead the values are generated following the
 *                          pattern: 'attrname_creationIndex#', i.e. the column
 *                          name suffixed with an underscore and a running
 *                          counter (starting at 0). For string types with
 *                          limited size (eg char4) the prefix is dropped. No
 *                          nulls will be generated for nullable columns.
 *                                  <li> 'null_percentage': If specified, then
 *                          generate the given percentage of the count as nulls
 *                          for all nullable columns.  This option will be
 *                          ignored for non-nullable columns.  The value must
 *                          be within the range [0, 1.0].  The default value is
 *                          5% (0.05).
 *                                  <li> 'cardinality': If specified, limit the
 *                          randomly generated values to a fixed set. Not
 *                          allowed on a column with interval specified, and is
 *                          not applicable to WKT or Track-specific columns.
 *                          The value must be greater than 0. This option is
 *                          disabled by default.
 *                          </ul>
 *                                  <li> 'attr_name': Use the desired column
 *                          name in place of <code>attr_name</code>, and set
 *                          the following parameters for the column specified.
 *                          This overrides any parameter set by
 *                          <code>all</code>.

 *                          for these columns in such cases are -180.0 and
