"KeyRange": {
"description": "KeyRange represents a range of rows in a table or index.\n\nA range has a start key and an end key. These keys can be open or\nclosed, indicating if the range includes rows with that key.\n\nKeys are represented by lists, where the ith value in the list\ncorresponds to the ith component of the table or index primary key.\nIndividual values are encoded as described here.\n\nFor example, consider the following table definition:\n\n CREATE TABLE UserEvents (\n UserName STRING(MAX),\n EventDate STRING(10)\n ) PRIMARY KEY(UserName, EventDate);\n\nThe following keys name rows in this table:\n\n \"Bob\", \"2014-09-23\"\n\nSince the `UserEvents` table's `PRIMARY KEY` clause names two\ncolumns, each `UserEvents` key has two elements; the first is the\n`UserName`, and the second is the `EventDate`.\n\nKey ranges with multiple components are interpreted\nlexicographically by component using the table or index key's declared\nsort order. For example, the following range returns all events for\nuser `\"Bob\"` that occurred in the year 2015:\n\n \"start_closed\": [\"Bob\", \"2015-01-01\"]\n \"end_closed\": [\"Bob\", \"2015-12-31\"]\n\nStart and end keys can omit trailing key components. This affects the\ninclusion and exclusion of rows that exactly match the provided key\ncomponents: if the key is closed, then rows that exactly match the\nprovided components are included; if the key is open, then rows\nthat exactly match are not included.\n\nFor example, the following range includes all events for `\"Bob\"` that\noccurred during and after the year 2000:\n\n \"start_closed\": [\"Bob\", \"2000-01-01\"]\n \"end_closed\": [\"Bob\"]\n\nThe next example retrieves all events for `\"Bob\"`:\n\n \"start_closed\": [\"Bob\"]\n \"end_closed\": [\"Bob\"]\n\nTo retrieve events before the year 2000:\n\n \"start_closed\": [\"Bob\"]\n \"end_open\": [\"Bob\", \"2000-01-01\"]\n\nThe following range includes all rows in the table:\n\n \"start_closed\": []\n \"end_closed\": []\n\nThis range returns all users whose `UserName` begins with any\ncharacter from A to C:\n\n \"start_closed\": [\"A\"]\n \"end_open\": [\"D\"]\n\nThis range returns all users whose `UserName` begins with B:\n\n \"start_closed\": [\"B\"]\n \"end_open\": [\"C\"]\n\nKey ranges honor column sort order. For example, suppose a table is\ndefined as follows:\n\n CREATE TABLE DescendingSortedTable {\n Key INT64,\n ...\n ) PRIMARY KEY(Key DESC);\n\nThe following range retrieves all rows with key values between 1\nand 100 inclusive:\n\n \"start_closed\": [\"100\"]\n \"end_closed\": [\"1\"]\n\nNote that 100 is passed as the start, and 1 is passed as the end,\nbecause `Key` is a descending column in the schema.",

"TransactionOptions": {
"description": "# Transactions\n\n\nEach session can have at most one active transaction at a time. After the\nactive transaction is completed, the session can immediately be\nre-used for the next transaction. It is not necessary to create a\nnew session for each transaction.\n\n# Transaction Modes\n\nCloud Spanner supports two transaction modes:\n\n 1. Locking read-write. This type of transaction is the only way\n to write data into Cloud Spanner. These transactions rely on\n pessimistic locking and, if necessary, two-phase commit.\n Locking read-write transactions may abort, requiring the\n application to retry.\n\n 2. Snapshot read-only. This transaction type provides guaranteed\n consistency across several reads, but does not allow\n writes. Snapshot read-only transactions can be configured to\n read at timestamps in the past. Snapshot read-only\n transactions do not need to be committed.\n\nFor transactions that only read, snapshot read-only transactions\nprovide simpler semantics and are almost always faster. In\nparticular, read-only transactions do not take locks, so they do\nnot conflict with read-write transactions. As a consequence of not\ntaking locks, they also do not abort, so retry loops are not needed.\n\nTransactions may only read/write data in a single database. They\nmay, however, read/write data in different tables within that\ndatabase.\n\n## Locking Read-Write Transactions\n\nLocking transactions may be used to atomically read-modify-write\ndata anywhere in a database. This type of transaction is externally\nconsistent.\n\nClients should attempt to minimize the amount of time a transaction\nis active. Faster transactions commit with higher probability\nand cause less contention. Cloud Spanner attempts to keep read locks\nactive as long as the transaction continues to do reads, and the\ntransaction has not been terminated by\nCommit or\nRollback. Long periods of\ninactivity at the client may cause Cloud Spanner to release a\ntransaction's locks and abort it.\n\nReads performed within a transaction acquire locks on the data\nbeing read. Writes can only be done at commit time, after all reads\nhave been completed.\nConceptually, a read-write transaction consists of zero or more\nreads or SQL queries followed by\nCommit. At any time before\nCommit, the client can send a\nRollback request to abort the\ntransaction.\n\n### Semantics\n\nCloud Spanner can commit the transaction if all read locks it acquired\nare still valid at commit time, and it is able to acquire write\nlocks for all writes. Cloud Spanner can abort the transaction for any\nreason. If a commit attempt returns `ABORTED`, Cloud Spanner guarantees\nthat the transaction has not modified any user data in Cloud Spanner.\n\nUnless the transaction commits, Cloud Spanner makes no guarantees about\nhow long the transaction's locks were held for. It is an error to\nuse Cloud Spanner locks for any sort of mutual exclusion other than\nbetween Cloud Spanner transactions themselves.\n\n### Retrying Aborted Transactions\n\nWhen a transaction aborts, the application can choose to retry the\nwhole transaction again. To maximize the chances of successfully\ncommitting the retry, the client should execute the retry in the\nsame session as the original attempt. The original session's lock\npriority increases with each consecutive abort, meaning that each\nattempt has a slightly better chance of success than the previous.\n\nUnder some circumstances (e.g., many transactions attempting to\nmodify the same row(s)), a transaction can abort many times in a\nshort period before successfully committing. Thus, it is not a good\nidea to cap the number of retries a transaction can attempt;\ninstead, it is better to limit the total amount of wall time spent\nretrying.\n\n### Idle Transactions\n\nA transaction is considered idle if it has no outstanding reads or\nSQL queries and has not started a read or SQL query within the last 10\nseconds. Idle transactions can be aborted by Cloud Spanner so that they\ndon't hold on to locks indefinitely. In that case, the commit will\nfail with error `ABORTED`.\n\nIf this behavior is undesirable, periodically executing a simple\nSQL query in the transaction (e.g., `SELECT 1`) prevents the\ntransaction from becoming idle.\n\n## Snapshot Read-Only Transactions\n\nSnapshot read-only transactions provides a simpler method than\nlocking read-write transactions for doing several consistent\nreads. However, this type of transaction does not support writes.\n\nSnapshot transactions do not take locks. Instead, they work by\nchoosing a Cloud Spanner timestamp, then executing all reads at that\ntimestamp. Since they do not acquire locks, they do not block\nconcurrent read-write transactions.\n\nUnlike locking read-write transactions, snapshot read-only\ntransactions never abort. They can fail if the chosen read\ntimestamp is garbage collected; however, the default garbage\ncollection policy is generous enough that most applications do not\nneed to worry about this in practice.\n\nSnapshot read-only transactions do not need to call\nCommit or\nRollback (and in fact are not\npermitted to do so).\n\nTo execute a snapshot transaction, the client specifies a timestamp\nbound, which tells Cloud Spanner how to choose a read timestamp.\n\nThe types of timestamp bound are:\n\n - Strong (the default).\n - Bounded staleness.\n - Exact staleness.\n\nIf the Cloud Spanner database to be read is geographically distributed,\nstale read-only transactions can execute more quickly than strong\nor read-write transaction, because they are able to execute far\nfrom the leader replica.\n\nEach type of timestamp bound is discussed in detail below.\n\n### Strong\n\nStrong reads are guaranteed to see the effects of all transactions\nthat have committed before the start of the read. Furthermore, all\nrows yielded by a single read are consistent with each other -- if\nany part of the read observes a transaction, all parts of the read\nsee the transaction.\n\nStrong reads are not repeatable: two consecutive strong read-only\ntransactions might return inconsistent results if there are\nconcurrent writes. If consistency across reads is required, the\nreads should be executed within a transaction or at an exact read\ntimestamp.\n\nSee TransactionOptions.ReadOnly.strong.\n\n### Exact Staleness\n\nThese timestamp bounds execute reads at a user-specified\ntimestamp. Reads at a timestamp are guaranteed to see a consistent\nprefix of the global transaction history: they observe\nmodifications done by all transactions with a commit timestamp \u003c=\nthe read timestamp, and observe none of the modifications done by\ntransactions with a larger commit timestamp. They will block until\nall conflicting transactions that may be assigned commit timestamps\n\u003c= the read timestamp have finished.\n\nThe timestamp can either be expressed as an absolute Cloud Spanner commit\ntimestamp or a staleness relative to the current time.\n\nThese modes do not require a \"negotiation phase\" to pick a\ntimestamp. As a result, they execute slightly faster than the\nequivalent boundedly stale concurrency modes. On the other hand,\nboundedly stale reads usually return fresher results.\n\nSee TransactionOptions.ReadOnly.read_timestamp and\nTransactionOptions.ReadOnly.exact_staleness.\n\n### Bounded Staleness\n\nBounded staleness modes allow Cloud Spanner to pick the read timestamp,\nsubject to a user-provided staleness bound. Cloud Spanner chooses the\nnewest timestamp within the staleness bound that allows execution\nof the reads at the closest available replica without blocking.\n\nAll rows yielded are consistent with each other -- if any part of\nthe read observes a transaction, all parts of the read see the\ntransaction. Boundedly stale reads are not repeatable: two stale\nreads, even if they use the same staleness bound, can execute at\ndifferent timestamps and thus return inconsistent results.\n\nBoundedly stale reads execute in two phases: the first phase\nnegotiates a timestamp among all replicas needed to serve the\nread. In the second phase, reads are executed at the negotiated\ntimestamp.\n\nAs a result of the two phase execution, bounded staleness reads are\nusually a little slower than comparable exact staleness\nreads. However, they are typically able to return fresher\nresults, and are more likely to execute at the closest replica.\n\nBecause the timestamp negotiation requires up-front knowledge of\nwhich rows will be read, it can only be used with single-use\nread-only transactions.\n\nSee TransactionOptions.ReadOnly.max_staleness and\nTransactionOptions.ReadOnly.min_read_timestamp.\n\n### Old Read Timestamps and Garbage Collection\n\nCloud Spanner continuously garbage collects deleted and overwritten data\nin the background to reclaim storage space. This process is known\nas \"version GC\". By default, version GC reclaims versions after they\nare one hour old. Because of this, Cloud Spanner cannot perform reads\nat read timestamps more than one hour in the past. This\nrestriction also applies to in-progress reads and/or SQL queries whose\ntimestamp become too old while executing.

"description": "The `Status` type defines a logical error model that is suitable for different\nprogramming environments, including REST APIs and RPC APIs. It is used by\n[gRPC](https://github.com/grpc). The error model is designed to be:\n\n- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error message,\nand error details. The error code should be an enum value of\ngoogle.rpc.Code, but it may accept additional error codes if needed. The\nerror message should be a developer-facing English message that helps\ndevelopers *understand* and *resolve* the error. If a localized user-facing\nerror message is needed, put the localized message in the error details or\nlocalize it in the client. The optional error details may contain arbitrary\ninformation about the error. There is a predefined set of error detail types\nin the package `google.rpc` that can be used for common error conditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n it may embed the `Status` in the normal response to indicate the partial\n errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n `Status` message should be used directly inside batch response, one for\n each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n results in its response, the status of those operations should be\n represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n be used directly after any stripping needed for security/privacy reasons.",
