|
|
* being the last value
|
|
* - `boolean` is ordered by `false` < `true`

|
|
*
|
|
* 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.
