Detailed Description

A set of output parameters for const.

For a given table, retrieves the values of the given columns within a given range. It returns maps of column name to the vector of values for each supported data type (double, float, long, int and string). This operation supports pagination feature, i.e. values that are retrieved are those associated with the indices between the start (offset) and end value (offset + limit) parameters (inclusive). If there are num_points values in the table then each of the indices between 0 and num_points-1 retrieves a unique value.

Note that when using the pagination feature, if the table (or the underlying table in case of a view) is updated (records are inserted, deleted or modified) the records or values retrieved may differ between calls (discontiguous or overlap) based on the type of the update.

The response is returned as a dynamic schema. For details see: dynamic schemas documentation.
