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.",

Two or more chunked values can be merged to form a\ncomplete value as follows:\n\n * `bool/number/null`: cannot be chunked\n * `string`: concatenate the strings\n * `list`: concatenate the lists. If the last element in a list is a\n `string`, `list`, or `object`, merge it with the first element in\n the next list by applying these rules recursively.\n * `object`: concatenate the (field name, field value) pairs. If a\n field name is duplicated, then apply these rules recursively\n to merge the field values.\n\nSome examples of merging:\n\n # Strings are concatenated.\n \"foo\", \"bar\" =\u003e \"foobar\"\n\n # Lists of non-strings are concatenated.\n [2, 3], [4] =\u003e [2, 3, 4]\n\n # Lists are concatenated, but the last and first elements are merged\n # because they are strings.\n [\"a\", \"b\"], [\"c\", \"d\"] =\u003e [\"a\", \"bc\", \"d\"]\n\n # Lists are concatenated, but the last and first elements are merged\n # because they are lists. Recursively, the last and first elements\n # of the inner lists are merged because they are strings.\n [\"a\", [\"b\", \"c\"]], [[\"d\"], \"e\"] =\u003e [\"a\", [\"b\", \"cd\"], \"e\"]\n\n # Non-overlapping object fields are combined.\n {\"a\": \"1\"}, {\"b\": \"2\"} =\u003e {\"a\": \"1\", \"b\": 2\"}\n\n # Overlapping object fields are merged.\n {\"a\": \"1\"}, {\"a\": \"2\"} =\u003e {\"a\": \"12\"}\n\n # Examples of merging objects containing lists of strings.\n {\"a\": [\"1\"]}, {\"a\": [\"2\"]} =\u003e {\"a\": [\"12\"]}\n\nFor a more complete example, suppose a streaming SQL query is\nyielding a result set whose rows contain a single string\nfield. The following `PartialResultSet`s might be yielded:\n\n {\n \"metadata\": { ... }\n \"values\": [\"Hello\", \"W\"]\n \"chunked_value\": true\n \"resume_token\": \"Af65...\"\n }\n {\n \"values\": [\"orl\"]\n \"chunked_value\": true\n \"resume_token\": \"Bqp2...\"\n }\n {\n \"values\": [\"d\"]\n \"resume_token\": \"Zx1B...\"\n }\n\nThis sequence of `PartialResultSet`s encodes two rows, one\ncontaining the field value `\"Hello\"`, and a second containing the\nfield value `\"World\" = \"W\" + \"orl\" + \"d\"`.",

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.",
