* A key-value database that can be used to store and retrieve data.
*
* Data is stored as key-value pairs, where the key is a {@linkcode Deno.KvKey}
* and the value is an arbitrary structured-serializable JavaScript value.
* Keys are ordered lexicographically as described in the documentation for
* {@linkcode Deno.KvKey}. Keys are unique within a database, and the last
* value set for a given key is the one that is returned when reading the
* key. Keys can be deleted from the database, in which case they will no
* longer be returned when reading keys.
*
* Values can be any structured-serializable JavaScript value (objects,
* arrays, strings, numbers, etc.). The special value {@linkcode Deno.KvU64}
* can be used to store 64-bit unsigned integers in the database. This special
* value can not be nested within other objects or arrays. In addition to the
* regular database mutation operations, the unsigned 64-bit integer value
* also supports `sum`, `max`, and `min` mutations.
*
* Keys are versioned on write by assigning the key an ever-increasing
* "versionstamp". The versionstamp represents the version of a key-value pair
* in the database at some point in time, and can be used to perform
* transactional operations on the database without requiring any locking.
* This is enabled by atomic operations, which can have conditions that ensure
* that the operation only succeeds if the versionstamp of the key-value pair
* matches an expected versionstamp.
*
* Keys have a maximum length of 2048 bytes after serialization. Values have a
* maximum length of 64 KiB after serialization. Serialization of both keys
* and values is somewhat opaque, but one can usually assume that the
* serialization of any value is about the same length as the resulting string
* of a JSON serialization of that same value. If theses limits are exceeded,
* an exception will be thrown.
