+ ===================================================
+ Open vSwitch Configuration Database Specification
+ ===================================================
+
+Basic Notation
+--------------
+
+The descriptions below use the following shorthand notations for JSON
+values. Additional notation is presented later.
+
+<string>
+
+ A JSON string.
+
+<id>
+
+ A JSON string matching [a-zA-Z_][a-zA-Z0-9_]*.
+
+ <id>s that begin with _ are reserved to the implementation and may
+ not be used by the user.
+
+<boolean>
+
+ A JSON true or false value.
+
+<number>
+
+ A JSON number.
+
+<integer>
+
+ A JSON number with an integer value, within a certain range
+ (currently -2**63...+2**63-1).
+
+Schema Format
+-------------
+
+An Open vSwitch configuration database consists of a set of tables,
+each of which has a number of columns and zero or more rows. A schema
+is represented by <database-schema>, as described below.
+
+<database-schema>
+
+ A JSON object with the following members:
+
+ "name": <id> required
+ "comment": <string> optional
+ "tables": {<id>: <table-schema>, ...} required
+
+ The "name" identifies the database as a whole. The "comment"
+ optionally provides more information about the database. The
+ value of "tables" is a JSON object whose names are table names and
+ whose values are <table-schema>s.
+
+<table-schema>
+
+ A JSON object with the following members:
+
+ "comment": <string> optional
+ "columns": {<id>: <column-schema>, ...} required
+
+ The "comment" optionally provides information about this table for
+ a human reader. The value of "tables" is a JSON object whose
+ names are table names and whose values are <column-schema>s.
+
+ Every table has the following columns whose definitions are not
+ included in the schema:
+
+ "_uuid": This column, which contains exactly one UUID value,
+ is initialized to a random value by the database engine when
+ it creates a row. It is read-only, and its value never
+ changes during the lifetime of a row.
+
+ "_version": Like "_uuid", this column contains exactly one
+ UUID value, initialized to a random value by the database
+ engine when it creates a row, and it is read-only. However,
+ its value changes to a new random value whenever any other
+ field in the row changes. Furthermore, its value is
+ ephemeral: when the database is closed and reopened, or when
+ the database process is stopped and then started again, each
+ "_version" also changes to a new random value.
+
+<column-schema>
+
+ A JSON object with the following members:
+
+ "comment": <string> optional
+ "type": <type> required
+ "ephemeral": <boolean> optional
+
+ The "comment" optionally provides information about this column
+ for a human reader. The "type" specifies the type of data stored
+ in this column. If "ephemeral" is specified as true, then this
+ column's values are not guaranteed to be durable; they may be lost
+ when the database restarts.
+
+<type>
+
+ The type of a database column. Either an <atomic-type> or a JSON
+ object that describes the type of a database column, with the
+ following members:
+
+ "key": <atomic-type> required
+ "value": <atomic-type> optional
+ "min": <integer> optional
+ "max": <integer> or "unlimited" optional
+
+ If "min" or "max" is not specified, each defaults to 1. If "max"
+ is specified as "unlimited", then there is no specified maximum
+ number of elements, although the implementation will enforce some
+ limit. After considering defaults, "min" must be at least 0,
+ "max" must be at least 1, and "max" must be greater than or equal
+ to "min".
+
+ If "min" and "max" are both 1 and "value" is not specified, the
+ type is the scalar type specified by "key".
+
+ If "min" is not 1 or "max" is not 1, or both, and "value" is not
+ specified, the type is a set of scalar type "key".
+
+ If "value" is specified, the type is a map from type "key" to type
+ "value".
+
+<atomic-type>
+
+ One of the strings "integer", "real", "boolean", "string", or
+ "uuid", representing the specified scalar type.
+
+Wire Protocol
+-------------
+
+The database wire protocol is implemented in JSON-RPC 1.0. It
+consists of the following JSON-RPC methods:
+
+get_schema
+..........
+
+Request object members:
+
+ "method": "get_schema" required
+ "params": [] required
+ "id": any JSON value except null required
+
+Response object members:
+
+ "result": <database-schema>
+ "error": null
+ "id": same "id" as request
+
+This operation retrieves a <database-schema> that describes the
+hosted database.
+
+transact
+........
+
+Request object members:
+
+ "method": "transact" required
+ "params": [<operation>*] required
+ "id": any JSON value except null required
+
+Response object members:
+
+ "result": [<object>*]
+ "error": null
+ "id": same "id" as request
+
+The "params" array for this method consists of zero or more JSON
+objects, each of which represents a single database operation. The
+"Operations" section below describes the valid operations.
+
+The value of "id" must be unique among all in-flight transactions
+within the current JSON-RPC session. Otherwise, the server may return
+a JSON-RPC error.
+
+The database server executes each of the specified operations in the
+specified order, except that if an operation fails, then the remaining
+operations are not executed.
+
+The set of operations is executed as a single atomic, consistent,
+isolated transaction. The transaction is committed only if every
+operation succeeds. Durability of the commit is not guaranteed unless
+the "commit" operation, with "durable" set to true, is included in the
+operation set (see below).
+
+Regardless of whether errors occur, the response is always a JSON-RPC
+response with null "error" and a "result" member that is an array with
+the same number of elements as "params". Each element of the "result"
+array corresponds to the same element of the "params" array. The
+"result" array elements may be interpreted as follows:
+
+ - A JSON object that does not contain an "error" member indicates
+ that the operation completed successfully. The specific members
+ of the object are specified below in the descriptions of
+ individual operations. Some operations do not produce any
+ results, in which case the object will have no members.
+
+ - A JSON object that contains a "error" member indicates that the
+ operation completed with an error. The value of the "error"
+ member is a short string, specified in this document, that
+ broadly indicates the class of the error. Besides the ones
+ listed for a specific operation, any operation may result in one
+ the following "error"s:
+
+ "error": "resources exhausted"
+
+ The operation or the transaction requires more resources
+ (memory, disk, CPU, etc.) than are currently available to
+ the database server.
+
+ "error": "syntax error"
+
+ The operation is not specified correctly: a required request
+ object member is missing, an unknown or unsupported request
+ object member is present, the operation attempts to act on a
+ table that does not exist, the operation modifies a
+ read-only table column, etc.
+
+ Database implementations may use "error" strings not specified
+ in this document to indicate errors that do not fit into any of
+ the specified categories.
+
+ Optionally, the object may include a "details" member, whose
+ value is a string that describes the error in more detail for
+ the benefit of a human user or administrator. The object may
+ also have other members that describe the error in more detail.
+ This document does not specify the names or values of these
+ members.
+
+ - A JSON null value indicates that the operation was not attempted
+ because a prior operation failed.
+
+In general, "result" contains some number of successful results,
+possibly followed by an error, in turn followed by enough JSON null
+values to match the number of elements in "params". There is one
+exception: if all of the operations succeed, but the results cannot be
+committed (e.g. due to I/O errors), then "result" will have one more
+element than "params", with the additional element describing the
+error.
+
+If "params" contains one or more "wait" operations, then the
+transaction may take an arbitrary amount of time to complete. The
+database implementation must be capable of accepting, executing, and
+replying to other transactions and other JSON-RPC requests while a
+transaction or transactions containing "wait" operations are
+outstanding on the same or different JSON-RPC sessions.
+
+The section "Notation for the Wire Protocol" below describes
+additional notation for use with the wire protocol. After that, the
+"Operations" section describes each operation.
+
+cancel
+......
+
+Request object members:
+
+ "method": "cancel" required
+ "params": the "id" for an outstanding request required
+ "id": null required
+
+Response object members:
+
+ <no response>
+
+This JSON-RPC notification instructs the database server to
+immediately complete or cancel the "transact" request whose "id" is
+the same as the notification's "params" value.
+
+If the "transact" request can be completed immediately, then the
+server sends a response in the form described for "transact", above.
+Otherwise, the server sends a JSON-RPC error response of the following
+form:
+
+ "result": null
+ "error": "canceled"
+ "id": the request "id" member
+
+The "cancel" notification itself has no reply.
+
+Notation for the Wire Protocol
+------------------------------
+
+<table>
+
+ An <id> that names a table.
+
+<column>
+
+ An <id> that names a table column.
+
+<row>
+
+ A JSON object that describes a table row or a subset of a table
+ row. Each member is the name of a table column paired with the
+ <value> of that column.
+
+<value>
+
+ A JSON value that represents the value of a column in a table row,
+ one of <atom>, a <set>, or a <map>.
+
+<atom>
+
+ A JSON value that represents a scalar value for a column, one of
+ <string>, <number>, <boolean>, <uuid>, <named-uuid>.
+
+<set>
+
+ A 2-element JSON array that represents a database set value. The
+ first element of the array must be the string "set" and the second
+ element must be an array of zero or more <atom>s giving the values
+ in the set. All of the <atom>s must have the same type.
+
+<map>
+
+ A 2-element JSON array that represents a database map value. The
+ first element of the array must be the string "map" and the second
+ element must be an array of zero or more <pair>s giving the values
+ in the map. All of the <pair>s must have the same key and value
+ types.
+
+ (JSON objects are not used to represent <map> because JSON only
+ allows string names in an object.)
+
+<pair>
+
+ A 2-element JSON array that represents a pair within a database
+ map. The first element is an <atom> that represents the key, the
+ second element is an <atom> that represents the value.
+
+<uuid>
+
+ A 2-element JSON array that represents a UUID. The first element
+ of the array must be the string "uuid" and the second element must
+ be a 36-character string giving the UUID in the format described
+ by RFC 4122. For example, the following <uuid> represents the
+ UUID 550e8400-e29b-41d4-a716-446655440000:
+
+ ["uuid", "550e8400-e29b-41d4-a716-446655440000"]
+
+<named-uuid>
+
+ A 2-element JSON array that represents the UUID of a row inserted
+ in a previous "insert" operation within the same transaction. The
+ first element of the array must be the string "named-uuid" and the
+ second element must be the string specified on a previous "insert"
+ operation's "uuid-name". For example, if a previous "insert"
+ operation specified a "uuid-name" of "myrow", the following
+ <named-uuid> represents the UUID created by that operation:
+
+ ["named-uuid", "myrow"]
+
+<condition>
+
+ A 3-element JSON array of the form [<column>, <function>,
+ <value>] that represents a test on a column value.
+
+ Except as otherwise specified below, <value> must have the same
+ type as <column>.
+
+ The meaning depends on the type of <column>:
+
+ integer
+ real
+
+ <function> must be "<", "<=", "==", "!=", ">=", ">",
+ "includes", or "excludes".
+
+ The test is true if the column's value satisfies the
+ relation <function> <value>, e.g. if the column has value
+ 1 and <value> is 2, the test is true if <function> is "<",
+ "<=" or "!=", but not otherwise.
+
+ "includes" is equivalent to "=="; "excludes" is equivalent
+ to "!=".
+
+ boolean
+ string
+ uuid
+
+ <function> must be "!=", "==", "includes", or "excludes".
+
+ If <function> is "==" or "includes", the test is true if
+ the column's value equals <value>. If <function> is "!="
+ or "excludes", the test is inverted.
+
+ set
+ map
+
+ <function> must be "!=", "==", "includes", or "excludes".
+
+ If <function> is "==", the test is true if the column's
+ value contains exactly the same values (for sets) or pairs
+ (for maps). If <function> is "!=", the test is inverted.
+
+ If <function> is "includes", the test is true if the
+ column's value contains all of the values (for sets) or
+ pairs (for maps) in <value>. The column's value may also
+ contain other values or pairs.
+
+ If <function> is "excludes", the test is true if the
+ column's value does not contain any of the values (for
+ sets) or pairs (for maps) in <value>. The column's value
+ may contain other values or pairs not in <value>.
+
+ If <function> is "includes" or "excludes", then the
+ required type of <value> is slightly relaxed, in that it
+ may have fewer than the minimum number of elements
+ specified by the column's type. If <function> is
+ "excludes", then the required type is additionally relaxed
+ in that <value> may have more than the maximum number of
+ elements specified by the column's type.
+
+<function>
+
+ One of "<", "<=", "==", "!=", ">=", ">", "includes", "excludes".
+
+Operations
+----------
+
+Each of the available operations is described below.
+
+insert
+......
+
+Request object members:
+
+ "op": "insert" required
+ "table": <table> required
+ "row": <row> required
+ "uuid-name": <string> optional
+
+Result object members:
+
+ "uuid": <uuid>
+
+Semantics:
+
+ Inserts "row" into "table". If "row" does not specify values
+ for all the columns in "table", those columns receive default
+ values.
+
+ The new row receives a new, randomly generated UUID, which is
+ returned as the "_uuid" member of the result. If "uuid-name"
+ is supplied, then the UUID is made available under that name
+ to later operations within the same transaction.
+
+select
+......
+
+Request object members:
+
+ "op": "select" required
+ "table": <table> required
+ "where": [<condition>*] required
+ "columns": [<column>*] optional
+
+Result object members:
+
+ "rows": [<row>*]
+
+Semantics:
+
+ Searches "table" for rows that match all the conditions specified
+ in "where". If "where" is an empty array, every row in "table" is
+ selected.
+
+ The "rows" member of the result is an array of objects. Each
+ object corresponds to a matching row, with each column
+ specified in "columns" as a member, the column's name as the
+ member name and its value as the member value. If "columns"
+ is not specified, all the table's columns are included. If
+ two rows of the result have the same values for all included
+ columns, only one copy of that row is included in "rows".
+ Specifying "_uuid" within "columns" will avoid dropping
+ duplicates, since every row has a unique UUID.
+
+ The ordering of rows within "rows" is unspecified.
+
+update
+......
+
+Request object members:
+
+ "op": "update" required
+ "table": <table> required
+ "where": [<condition>*] required
+ "row": <row> required
+
+Result object members:
+
+ "count": <integer>
+
+Semantics:
+
+ Updates rows in a table.
+
+ Searches "table" for rows that match all the conditions
+ specified in "where". For each matching row, changes the
+ value of each column specified in "row" to the value for that
+ column specified in "row".
+
+ The "_uuid" and "_version" columns of a table may not be updated.
+ Columns designated read-only in the schema also may not be
+ updated.
+
+ The "count" member of the result specifies the number of rows
+ that matched.
+
+delete
+......
+
+Request object members:
+
+ "op": "delete" required
+ "table": <table> required
+ "where": [<condition>*] required
+
+Result object members:
+
+ "count": <integer>
+
+Semantics:
+
+ Deletes all the rows from "table" that match all the conditions
+ specified in "where".
+
+ The "count" member of the result specifies the number of deleted
+ rows.
+
+wait
+....
+
+Request object members:
+
+ "op": "wait" required
+ "timeout": <integer> optional
+ "table": <table> required
+ "where": [<condition>*] required
+ "columns": [<column>*] required
+ "until": "==" or "!=" required
+ "rows": [<row>*] required
+
+Result object members:
+
+ none
+
+Semantics:
+
+ Waits until a condition becomes true.
+
+ If "until" is "==", checks whether the query on "table" specified
+ by "where" and "columns", which is evaluated in the same way as
+ specified for "select", returns the result set specified by
+ "rows". If it does, then the operation completes successfully.
+ Otherwise, the entire transaction rolls back. It is automatically
+ restarted later, after a change in the database makes it possible
+ for the operation to succeed. The client will not receive a
+ response until the operation permanently succeeds or fails.
+
+ If "until" is "!=", the sense of the test is negated. That is, as
+ long as the query on "table" specified by "where" and "columns"
+ returns "rows", the transaction will be rolled back and restarted
+ later.
+
+ If "timeout" is specified, then the transaction aborts after the
+ specified number of milliseconds. The transaction is guaranteed
+ to be attempted at least once before it aborts. A "timeout" of 0
+ will abort the transaction on the first mismatch.
+
+Errors:
+
+ "error": "not supported"
+
+ One or more of the columns in this table do not support
+ triggers. This error will not occur if "timeout" is 0.
+
+ "error": "timed out"
+
+ The "timeout" was reached before the transaction was able to
+ complete.
+
+commit
+......
+
+Request object members:
+
+ "op": "commit" required
+ "durable": <boolean> required
+
+Result object members:
+
+ none
+
+Semantics:
+
+ If "durable" is specified as true, then the transaction, if it
+ commits, will be stored durably (to disk) before the reply is sent
+ to the client.
+
+Errors:
+
+ "error": "not supported"
+
+ When "durable" is true, this database implementation does not
+ support durable commits.
+
+abort
+.....
+
+Request object members:
+
+ "op": "abort" required
+
+Result object members:
+
+ (never succeeds)
+
+Semantics:
+
+ Aborts the transaction with an error. This may be useful for
+ testing.
+
+Errors:
+
+ "error": "aborted"
+
+ This operation always fails with this error.
