// KeyRange represents a range of rows in a table or index.
//
// A range has a start key and an end key. These keys can be open or
// closed, indicating if the range includes rows with that key.
//
// Keys are represented by lists, where the ith value in the list
// corresponds to the ith component of the table or index primary key.
// Individual values are encoded as described [here][google.spanner.v1.TypeCode].
//
// For example, consider the following table definition:
//
//     CREATE TABLE UserEvents (
//       UserName STRING(MAX),
//       EventDate STRING(10)
//     ) PRIMARY KEY(UserName, EventDate);
//
// The following keys name rows in this table:
//
//     ["Bob", "2014-09-23"]
//     ["Alfred", "2015-06-12"]
//
// Since the `UserEvents` table's `PRIMARY KEY` clause names two
// columns, each `UserEvents` key has two elements; the first is the
// `UserName`, and the second is the `EventDate`.
//
// Key ranges with multiple components are interpreted
// lexicographically by component using the table or index key's declared
// sort order. For example, the following range returns all events for
// user `"Bob"` that occurred in the year 2015:
//
//     "start_closed": ["Bob", "2015-01-01"]
//     "end_closed": ["Bob", "2015-12-31"]
//
// Start and end keys can omit trailing key components. This affects the
// inclusion and exclusion of rows that exactly match the provided key
// components: if the key is closed, then rows that exactly match the
// provided components are included; if the key is open, then rows
// that exactly match are not included.
//
// For example, the following range includes all events for `"Bob"` that
// occurred during and after the year 2000:
//
//     "start_closed": ["Bob", "2000-01-01"]
//     "end_closed": ["Bob"]
//
// The next example retrieves all events for `"Bob"`:
//
//     "start_closed": ["Bob"]
//     "end_closed": ["Bob"]
//
// To retrieve events before the year 2000:
//
//     "start_closed": ["Bob"]
//     "end_open": ["Bob", "2000-01-01"]
//
// The following range includes all rows in the table:
//
//     "start_closed": []
//     "end_closed": []
//
// This range returns all users whose `UserName` begins with any
// character from A to C:
//
//     "start_closed": ["A"]
//     "end_open": ["D"]
//
// This range returns all users whose `UserName` begins with B:
//
//     "start_closed": ["B"]
//     "end_open": ["C"]
//
// Key ranges honor column sort order. For example, suppose a table is
// defined as follows:
//
//     CREATE TABLE DescendingSortedTable {
//       Key INT64,
//       ...
//     ) PRIMARY KEY(Key DESC);
//
// The following range retrieves all rows with key values between 1
// and 100 inclusive:
//
//     "start_closed": ["100"]
//     "end_closed": ["1"]
//
// Note that 100 is passed as the start, and 1 is passed as the end,
// because `Key` is a descending column in the schema.
