// Package spanner provides access to the Cloud Spanner API.
//
// This package is DEPRECATED. Use package cloud.google.com/go/spanner instead.
//
// For product documentation, see: https://cloud.google.com/spanner/
//
// # Library status
//
// These client libraries are officially supported by Google. However, this
// library is considered complete and is in maintenance mode. This means
// that we will address critical bugs and security issues but will not add
// any new features.
//
// When possible, we recommend using our newer
// [Cloud Client Libraries for Go](https://pkg.go.dev/cloud.google.com/go)
// that are still actively being worked and iterated on.
//
// # Creating a client
//
// Usage example:
//
//	import "google.golang.org/api/spanner/v1"
//	...
//	ctx := context.Background()
//	spannerService, err := spanner.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for
// authentication. For information on how to create and obtain Application
// Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// # Other authentication options
//
// By default, all available scopes (see "Constants") are used to authenticate.
// To restrict scopes, use [google.golang.org/api/option.WithScopes]:
//
//	spannerService, err := spanner.NewService(ctx, option.WithScopes(spanner.SpannerDataScope))
//
// To use an API key for authentication (note: some APIs do not support API
// keys), use [google.golang.org/api/option.WithAPIKey]:
//
//	spannerService, err := spanner.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth
// flow, use [google.golang.org/api/option.WithTokenSource]:
//
//	config := &oauth2.Config{...}
//	// ...
//	token, err := config.Exchange(ctx, ...)
//	spannerService, err := spanner.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See [google.golang.org/api/option.ClientOption] for details on options.

// KeyRange: 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.
// 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" 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"]

	// "d"] => ["a", "bc", "d"] Lists are concatenated, but the last and first
	// elements are merged because they are lists. Recursively, the last and first
	// elements of the inner lists are merged because they are strings. ["a", ["b",
	// "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"] Non-overlapping object fields
	// are combined. {"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"} Overlapping
	// object fields are merged. {"a": "1"}, {"a": "2"} => {"a": "12"} Examples of
	// merging objects containing lists of strings. {"a": ["1"]}, {"a": ["2"]} =>
	// {"a": ["12"]} For a more complete example, suppose a streaming SQL query is
	// yielding a result set whose rows contain a single string field. The
	// following `PartialResultSet`s might be yielded: { "metadata": { ... }
	// "values": ["Hello", "W"] "chunked_value": true "resume_token": "Af65..." } {
	// "values": ["orl"] "chunked_value": true } { "values": ["d"] "resume_token":

// Policy: An Identity and Access Management (IAM) policy, which specifies
// access controls for Google Cloud resources. A `Policy` is a collection of
// `bindings`. A `binding` binds one or more `members`, or principals, to a
// single `role`. Principals can be user accounts, service accounts, Google
// groups, and domains (such as G Suite). A `role` is a named list of
// permissions; each `role` can be an IAM predefined role or a user-created
// custom role. For some types of Google Cloud resources, a `binding` can also
// specify a `condition`, which is a logical expression that allows access to a
// resource only if the expression evaluates to `true`. A condition can add
// constraints based on attributes of the request, the resource, or both. To
// learn which resources support conditions in their IAM policies, see the IAM
// documentation
// (https://cloud.google.com/iam/help/conditions/resource-policies). **JSON
// example:** ``` { "bindings": [ { "role":
// "roles/resourcemanager.organizationAdmin", "members": [
// "user:mike@example.com", "group:admins@example.com", "domain:google.com",
// "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role":

	// Possible values:
	//   "LOCK_HINT_UNSPECIFIED" - Default value. `LOCK_HINT_UNSPECIFIED` is
	// equivalent to `LOCK_HINT_SHARED`.
	//   "LOCK_HINT_SHARED" - Acquire shared locks. By default when you perform a
	// read as part of a read-write transaction, Spanner acquires shared read
	// locks, which allows other reads to still access the data until your
	// transaction is ready to commit. When your transaction is committing and
	// writes are being applied, the transaction attempts to upgrade to an
	// exclusive lock for any data you are writing. For more information about
	// locks, see [Lock
	// modes](https://cloud.google.com/spanner/docs/introspection/lock-statistics#ex
	// plain-lock-modes).
	//   "LOCK_HINT_EXCLUSIVE" - Acquire exclusive locks. Requesting exclusive
	// locks is beneficial if you observe high write contention, which means you
	// notice that multiple transactions are concurrently trying to read and write
	// to the same data, resulting in a large number of aborts. This problem occurs
	// when two transactions initially acquire shared locks and then both try to
	// upgrade to exclusive locks at the same time. In this situation both
	// transactions are waiting for the other to give up their lock, resulting in a
	// deadlocked situation. Spanner is able to detect this occurring and force one
	// of the transactions to abort. However, this is a slow and expensive
	// operation and results in lower performance. In this case it makes sense to
	// acquire exclusive locks at the start of the transaction because then when
	// multiple transactions try to act on the same data, they automatically get
	// serialized. Each transaction waits its turn to acquire the lock and avoids
	// getting into deadlock situations. Because the exclusive lock hint is just a
	// hint, it shouldn't be considered equivalent to a mutex. In other words, you
	// shouldn't use Spanner exclusive locks as a mutual exclusion mechanism for
	// the execution of code outside of Spanner. **Note:** Request exclusive locks
	// judiciously because they block others from reading that data for the entire
	// transaction, rather than just when the writes are being performed. Unless
	// you observe high write contention, you should use the default of shared read
	// locks so you don't prematurely block other clients from reading the data
	// that you're writing to.
	LockHint string `json:"lockHint,omitempty"`
	// OrderBy: Optional. Order for the returned rows. By default, Spanner returns

	// Spanner to optimize row retrieval, resulting in lower latencies in certain
	// cases (for example, bulk point lookups).
