// 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/
//
// # 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 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 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 option.WithTokenSource:
//
//	config := &oauth2.Config{...}
//	// ...
//	token, err := config.Exchange(ctx, ...)
//	spannerService, err := spanner.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See https://godoc.org/google.golang.org/api/option/ 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"] "end_closed": ["1"] Note that 100 is passed as the start, and

// 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": [

// TransactionOptions: Transactions: Each session can have at most one

// use a transaction internally and do count towards the one transaction
// limit). After the active transaction is completed, the session can
// immediately be re-used for the next transaction. It is not necessary
// to create a new session for each transaction. Transaction modes:
// Cloud Spanner supports three transaction modes: 1. Locking
// read-write. This type of transaction is the only way to write data
// into Cloud Spanner. These transactions rely on pessimistic locking
// and, if necessary, two-phase commit. Locking read-write transactions
// may abort, requiring the application to retry. 2. Snapshot read-only.
// Snapshot read-only transactions provide guaranteed consistency across
// several reads, but do not allow writes. Snapshot read-only
// transactions can be configured to read at timestamps in the past, or
// configured to perform a strong read (where Spanner will select a
// timestamp such that the read is guaranteed to see the effects of all
// transactions that have committed before the start of the read).
// Snapshot read-only transactions do not need to be committed. Queries
// on change streams must be performed with the snapshot read-only
// transaction mode, specifying a strong read. Please see
// TransactionOptions.ReadOnly.strong for more details. 3. Partitioned
// DML. This type of transaction is used to execute a single Partitioned
// DML statement. Partitioned DML partitions the key space and runs the
// DML statement over each partition in parallel using separate,
// internal transactions that commit independently. Partitioned DML
// transactions do not need to be committed. For transactions that only
// read, snapshot read-only transactions provide simpler semantics and
// are almost always faster. In particular, read-only transactions do
// not take locks, so they do not conflict with read-write transactions.
// As a consequence of not taking locks, they also do not abort, so
// retry loops are not needed. Transactions may only read-write data in
// a single database. They may, however, read-write data in different
// tables within that database. Locking read-write transactions: Locking
// transactions may be used to atomically read-modify-write data
// anywhere in a database. This type of transaction is externally
// consistent. Clients should attempt to minimize the amount of time a
// transaction is active. Faster transactions commit with higher
// probability and cause less contention. Cloud Spanner attempts to keep
// read locks active as long as the transaction continues to do reads,
// and the transaction has not been terminated by Commit or Rollback.
// Long periods of inactivity at the client may cause Cloud Spanner to
// release a transaction's locks and abort it. Conceptually, a
// read-write transaction consists of zero or more reads or SQL
// statements followed by Commit. At any time before Commit, the client
// can send a Rollback request to abort the transaction. Semantics:
// Cloud Spanner can commit the transaction if all read locks it
// acquired are still valid at commit time, and it is able to acquire
// write locks for all writes. Cloud Spanner can abort the transaction
// for any reason. If a commit attempt returns `ABORTED`, Cloud Spanner
// guarantees that the transaction has not modified any user data in
// Cloud Spanner. Unless the transaction commits, Cloud Spanner makes no
// guarantees about how long the transaction's locks were held for. It
// is an error to use Cloud Spanner locks for any sort of mutual
// exclusion other than between Cloud Spanner transactions themselves.
// Retrying aborted transactions: When a transaction aborts, the
// application can choose to retry the whole transaction again. To
// maximize the chances of successfully committing the retry, the client
// should execute the retry in the same session as the original attempt.
// The original session's lock priority increases with each consecutive
// abort, meaning that each attempt has a slightly better chance of
// success than the previous. Under some circumstances (for example,
// many transactions attempting to modify the same row(s)), a
// transaction can abort many times in a short period before
// successfully committing. Thus, it is not a good idea to cap the
// number of retries a transaction can attempt; instead, it is better to
// limit the total amount of time spent retrying. Idle transactions: A
// transaction is considered idle if it has no outstanding reads or SQL
// queries and has not started a read or SQL query within the last 10
// seconds. Idle transactions can be aborted by Cloud Spanner so that
// they don't hold on to locks indefinitely. If an idle transaction is
// aborted, the commit will fail with error `ABORTED`. If this behavior
// is undesirable, periodically executing a simple SQL query in the
// transaction (for example, `SELECT 1`) prevents the transaction from
// becoming idle. Snapshot read-only transactions: Snapshot read-only
// transactions provides a simpler method than locking read-write
// transactions for doing several consistent reads. However, this type
// of transaction does not support writes. Snapshot transactions do not
// take locks. Instead, they work by choosing a Cloud Spanner timestamp,
// then executing all reads at that timestamp. Since they do not acquire
// locks, they do not block concurrent read-write transactions. Unlike
// locking read-write transactions, snapshot read-only transactions
// never abort. They can fail if the chosen read timestamp is garbage
// collected; however, the default garbage collection policy is generous
// enough that most applications do not need to worry about this in
// practice. Snapshot read-only transactions do not need to call Commit
// or Rollback (and in fact are not permitted to do so). To execute a
// snapshot transaction, the client specifies a timestamp bound, which
// tells Cloud Spanner how to choose a read timestamp. The types of
// timestamp bound are: - Strong (the default). - Bounded staleness. -
// Exact staleness. If the Cloud Spanner database to be read is
// geographically distributed, stale read-only transactions can execute
// more quickly than strong or read-write transactions, because they are
// able to execute far from the leader replica. Each type of timestamp
// bound is discussed in detail below. Strong: Strong reads are
// guaranteed to see the effects of all transactions that have committed
// before the start of the read. Furthermore, all rows yielded by a
// single read are consistent with each other -- if any part of the read
// observes a transaction, all parts of the read see the transaction.
// Strong reads are not repeatable: two consecutive strong read-only
// transactions might return inconsistent results if there are
// concurrent writes. If consistency across reads is required, the reads
// should be executed within a transaction or at an exact read
// timestamp. Queries on change streams (see below for more details)
// must also specify the strong read timestamp bound. See
// TransactionOptions.ReadOnly.strong. Exact staleness: These timestamp
// bounds execute reads at a user-specified timestamp. Reads at a
// timestamp are guaranteed to see a consistent prefix of the global
// transaction history: they observe modifications done by all
// transactions with a commit timestamp less than or equal to the read
// timestamp, and observe none of the modifications done by transactions
// with a larger commit timestamp. They will block until all conflicting
// transactions that may be assigned commit timestamps <= the read
// timestamp have finished. The timestamp can either be expressed as an
// absolute Cloud Spanner commit timestamp or a staleness relative to
// the current time. These modes do not require a "negotiation phase" to
// pick a timestamp. As a result, they execute slightly faster than the
// equivalent boundedly stale concurrency modes. On the other hand,
// boundedly stale reads usually return fresher results. See
// TransactionOptions.ReadOnly.read_timestamp and
// TransactionOptions.ReadOnly.exact_staleness. Bounded staleness:
// Bounded staleness modes allow Cloud Spanner to pick the read
// timestamp, subject to a user-provided staleness bound. Cloud Spanner
// chooses the newest timestamp within the staleness bound that allows
// execution of the reads at the closest available replica without
// blocking. All rows yielded are consistent with each other -- if any
// part of the read observes a transaction, all parts of the read see
// the transaction. Boundedly stale reads are not repeatable: two stale
// reads, even if they use the same staleness bound, can execute at
// different timestamps and thus return inconsistent results. Boundedly
// stale reads execute in two phases: the first phase negotiates a
// timestamp among all replicas needed to serve the read. In the second
// phase, reads are executed at the negotiated timestamp. As a result of
// the two phase execution, bounded staleness reads are usually a little
// slower than comparable exact staleness reads. However, they are
// typically able to return fresher results, and are more likely to
// execute at the closest replica. Because the timestamp negotiation
// requires up-front knowledge of which rows will be read, it can only
// be used with single-use read-only transactions. See
// TransactionOptions.ReadOnly.max_staleness and
// TransactionOptions.ReadOnly.min_read_timestamp. Old read timestamps
// and garbage collection: Cloud Spanner continuously garbage collects
// deleted and overwritten data in the background to reclaim storage
// space. This process is known as "version GC". By default, version GC
// reclaims versions after they are one hour old. Because of this, Cloud
// Spanner cannot perform reads at read timestamps more than one hour in
// the past. This restriction also applies to in-progress reads and/or
// SQL queries whose timestamp become too old while executing. Reads and
// SQL queries with too-old read timestamps fail with the error
// `FAILED_PRECONDITION`. You can configure and extend the
// `VERSION_RETENTION_PERIOD` of a database up to a period as long as
// one week, which allows Cloud Spanner to perform reads up to one week
// in the past. Querying change Streams: A Change Stream is a schema
// object that can be configured to watch data changes on the entire
// database, a set of tables, or a set of columns in a database. When a
// change stream is created, Spanner automatically defines a
// corresponding SQL Table-Valued Function (TVF) that can be used to
// query the change records in the associated change stream using the
// ExecuteStreamingSql API. The name of the TVF for a change stream is
// generated from the name of the change stream: READ_. All queries on
// change stream TVFs must be executed using the ExecuteStreamingSql API
// with a single-use read-only transaction with a strong read-only
// timestamp_bound. The change stream TVF allows users to specify the
// start_timestamp and end_timestamp for the time range of interest. All
// change records within the retention period is accessible using the
// strong read-only timestamp_bound. All other TransactionOptions are
// invalid for change stream queries. In addition, if
// TransactionOptions.read_only.return_read_timestamp is set to true, a
// special value of 2^63 - 2 will be returned in the Transaction message
// that describes the transaction, instead of a valid read timestamp.
// This special value should be discarded and not used for any
// subsequent queries. Please see
// https://cloud.google.com/spanner/docs/change-streams for more details
// on how to query the change stream TVFs. Partitioned DML transactions:
// Partitioned DML transactions are used to execute DML statements with
// a different execution strategy that provides different, and often
// better, scalability properties for large, table-wide operations than
// DML in a ReadWrite transaction. Smaller scoped statements, such as an
// OLTP workload, should prefer using ReadWrite transactions.
// Partitioned DML partitions the keyspace and runs the DML statement on
// each partition in separate, internal transactions. These transactions
// commit automatically when complete, and run independently from one
// another. To reduce lock contention, this execution strategy only
// acquires read locks on rows that match the WHERE clause of the
// statement. Additionally, the smaller per-partition transactions hold
// locks for less time. That said, Partitioned DML is not a drop-in
// replacement for standard DML used in ReadWrite transactions. - The
// DML statement must be fully-partitionable. Specifically, the
// statement must be expressible as the union of many statements which
// each access only a single row of the table. - The statement is not
// applied atomically to all rows of the table. Rather, the statement is
// applied atomically to partitions of the table, in independent
// transactions. Secondary index rows are updated atomically with the
// base table rows. - Partitioned DML does not guarantee exactly-once
// execution semantics against a partition. The statement will be
// applied at least once to each partition. It is strongly recommended
// that the DML statement should be idempotent to avoid unexpected
// results. For instance, it is potentially dangerous to run a statement
// such as `UPDATE table SET column = column + 1` as it could be run
// multiple times against some rows. - The partitions are committed
// automatically - there is no support for Commit or Rollback. If the
// call returns an error, or if the client issuing the ExecuteSql call
// dies, it is possible that some rows had the statement executed on
// them successfully. It is also possible that statement was never
// executed against other rows. - Partitioned DML transactions may only
// contain the execution of a single DML statement via ExecuteSql or
// ExecuteStreamingSql. - If any error is encountered during the
// execution of the partitioned DML operation (for instance, a UNIQUE
// INDEX violation, division by zero, or a value that cannot be stored
// due to schema constraints), then the operation is stopped at that
// point and an error is returned. It is possible that at this point,
// some partitions have been committed (or even committed multiple
// times), and other partitions have not been run at all. Given the
// above, Partitioned DML is good fit for large, database-wide,
// operations that are idempotent, such as deleting old rows from a very
// large table.
