        brief: >
          This attribute is used to report the name of the database being accessed.
          For commands that switch the database, this should be set to the target database
          (even if the command fails).
        note: >
          In some SQL databases, the database name to be used is called "schema name".
          In case there are multiple layers that could be considered for database name
          (e.g. Oracle instance name and schema name),
          the database name to be used is the more specific layer (e.g. Oracle schema name).
        examples: [ 'customers', 'main' ]

          such as `findAndModify`, or the SQL keyword.
        note: >
          When setting this to an SQL keyword, it is not recommended to
          attempt any client-side parsing of `db.statement` just to get this
          property, but it should be set if the operation name is provided by
          the library being instrumented.
          If the SQL statement has an ambiguous operation, or performs more
          than one operation, this value may be omitted.

        note: >
          This mirrors the db.sql.table attribute but references cassandra rather than sql.
          It is not recommended to attempt any client-side parsing of
          `db.statement` just to get this property, but it should be set if
          it is provided by the library being instrumented.
          If the operation is acting upon an anonymous table, or more than one table, this
          value MUST NOT be set.

          The HTTP method + the target REST route.
        examples: ['GET /{db}/{docid}']
        note: >
          In **CouchDB**, `db.operation` should be set to the HTTP method +
          the target REST route according to the API reference documentation.
          For example, when retrieving a document, `db.operation` would be set to
          (literally, i.e., without replacing the placeholders with concrete values):
          [`GET /{db}/{docid}`](http://docs.couchdb.org/en/stable/api/document/common.html#get--db-docid).

        examples: [0, 1, 15]
      - ref: db.statement
        tag: call-level-tech-specific
        brief: >
          The full syntax of the Redis CLI command.
        examples: ["HMSET myhash field1 'Hello' field2 'World'"]
        note: >
          For **Redis**, the value provided for `db.statement` SHOULD correspond to the syntax of the Redis CLI.
          If, for example, the [`HMSET` command](https://redis.io/commands/hmset) is invoked, `"HMSET myhash field1 'Hello' field2 'World'"` would be a suitable value for `db.statement`.
