// 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

// represented by lists, where the ith value in the list corresponds to

// 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

// "start_closed": ["A"] "end_open": ["D"] This range returns all users

// 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

// attributes of the request, the resource, or both. To learn which

// TransactionOptions: # Transactions Each session can have at most one
// active transaction at a time (note that standalone reads and queries
// 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.
// This transaction type provides guaranteed consistency across several
// reads, but does not allow writes. Snapshot read-only transactions can
// be configured to read at timestamps in the past. Snapshot read-only
// transactions do not need to be committed. 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 (e.g., 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 wall 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. In that case, the commit
// will fail with error `ABORTED`. If this behavior is undesirable,
// periodically executing a simple SQL query in the transaction (e.g.,
// `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 transaction, 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. 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 <= 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`. ## 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.

To execute multiple concurrent read-write/write-only transactions, create multiple sessions. Note that standalone reads and queries use a transaction internally, and count toward the one transaction limit. Active sessions use additional server resources, so it is a good idea to delete idle and unneeded sessions. Aside from explicit deletes, Cloud Spanner may delete sessions for which no operations are sent for more than an hour. If a session is deleted, requests to it return `NOT_FOUND`. Idle sessions can be kept alive by sending a trivial SQL query periodically, e.g., `\"SELECT 1\"`.",
