# deno_kv
|
||||
|
||||
This crate provides a key/value store for Deno.
|
||||
This crate provides a key/value store for Deno. For an overview of Deno KV,
|
||||
please read the [manual](https://deno.land/manual/runtime/kv).
|
||||
|
||||
## Storage Backends
|
||||
|
||||
Deno KV has a pluggable storage interface that supports multiple backends:
|
||||
|
||||
- SQLite - backed by a local SQLite database. This backend is suitable for
|
||||
development and is the default when running locally.
|
||||
- Remote - backed by a remote service that implements the
|
||||
[KV Connect](#kv-connect) protocol, for example
|
||||
[Deno Deploy](https://deno.com/deploy).
|
||||
|
||||
Additional backends can be added by implementing the `DatabaseHandler` trait.
|
||||
|
||||
## KV Connect
|
||||
|
||||
The KV Connect protocol has separate control and data planes to maximize
|
||||
throughput and minimize latency. _Metadata Exchange_ and _Data Path_ are the two
|
||||
sub-protocols that are used when talking to a KV Connect-compatible service.
|
||||
|
||||
### Metadata Exchange
|
||||
|
||||
To connect to a KV Connect service, the user provides an HTTP or HTTPS URL to
|
||||
`Deno.openKv`. A background task is then spawned to periodically make HTTP POST
|
||||
requests to the provided URL to refresh database metadata.
|
||||
|
||||
The HTTP `Authorization` header is included and have the format
|
||||
`Bearer <access-token>`. The `<access-token>` is a static token issued by the
|
||||
service provider. For Deno Deploy, this is the personal access token generated
|
||||
from the dashboard. You can specify the access token with the environment
|
||||
variable `DENO_KV_ACCESS_TOKEN`.
|
||||
|
||||
Request body is currently unused. The response is a JSON message that satisfies
|
||||
the [JSON Schema](https://json-schema.org/) definition in
|
||||
`cli/schemas/kv-metadata-exchange-response.v1.json`.
|
||||
|
||||
Semantics of the response fields:
|
||||
|
||||
- `version`: Protocol version. The only supported value is `1`.
|
||||
- `databaseId`: UUID of the database.
|
||||
- `endpoints`: Data plane endpoints that can serve requests to the database,
|
||||
along with their consistency levels.
|
||||
- `token`: An ephemeral authentication token that must be included in all
|
||||
requests to the data plane. This value is an opaque string and the client
|
||||
should not depend on its format.
|
||||
- `expiresAt`: The time at which the token expires. Encoded as an ISO 8601
|
||||
string.
|
||||
|
||||
### Data Path
|
||||
|
||||
After the first metadata exchange has completed, the client can talk to the data
|
||||
plane endpoints listed in the `endpoints` field using a Protobuf-over-HTTP
|
||||
protocol called the _Data Path_. The Protobuf messages are defined in
|
||||
`proto/datapath.proto`.
|
||||
|
||||
Two sub-endpoints are available under a data plane endpoint URL:
|
||||
|
||||
- `POST /snapshot_read`: Used for read operations: `kv.get()` and
|
||||
`kv.getMany()`.
|
||||
- **Request type**: `SnapshotRead`
|
||||
- **Response type**: `SnapshotReadOutput`
|
||||
- `POST /atomic_write`: Used for write operations: `kv.set()` and
|
||||
`kv.atomic().commit()`.
|
||||
- **Request type**: `AtomicWrite`
|
||||
- **Response type**: `AtomicWriteOutput`
|
||||
|
||||
An HTTP `Authorization` header in the format `Bearer <ephemeral-token>` must be
|
||||
included in all requests to the data plane. The value of `<ephemeral-token>` is
|
||||
the `token` field from the metadata exchange response.
|
||||
|
||||
### Error handling
|
||||
|
||||
All non-client errors (i.e. network errors and HTTP 5xx status codes) are
|
||||
handled by retrying the request. Randomized exponential backoff is applied to
|
||||
each retry.
|
||||
|
||||
Client errors cannot be recovered by retrying. A JavaScript exception is
|
||||
generated for each of those errors.
