API Notes

kv, err := js.KeyValue("bucket name")
Type Methods
KeyValue Bucket, Delete, Create, Update, Put, Get, Status, History, Keys, Purge, PurgeAll, Watch, WatchAll
KeyValueEntry Key, Value, Revision, Operation, Delta, Bucket, Created
Status Values, TTL, History, Bucket, BackingStore, StreamInfo (when cast to *nats.keyValueBucketStatus)
KeyWatcher Stop, Updates

Notes:

  • A watcher (via Updates) initially returns the current KeyValueEntry (if any) then a nil KeyValueEntry. Subsequent entries represent changes since watcher instantiated.
