def dequeueValue(dirKey: String): Future[String]

Dequeue a value when (mis)using etcd as queueing service.
Dequeue a value when (mis)using etcd as queueing service.
The queue is supposed to behave like a fifo and ony once client is supposed to receive the value.
dirKey
the directory node to use for queuing
returns
dequed value
def enqueueValue(dirKey: String, value: String, ttl: Option[Long] = None): Future[String]

Enqueue a value when (mis)using etcd as queueing service.
Enqueue a value when (mis)using etcd as queueing service.
The queue is supposed to behave like a fifo and ony once client is supposed to receive the value.
dirKey
the directory node to use for queuing
value
the value to enqueue
ttl
Optional time to live of the value
returns
the key of the enqueued node

def getValues(key: String): Future[Seq[String]]

Get value helper.
Get value helper.
Value nodes will result in a sequence with one element. If node does not exists, result will be empty. if it is a directory a the values of all child value nodes are returned

def lock[T](key: String, ttl: Option[Long] = None)(block: ⇒ T): Future[Try[T]]

Lock a code block via etcd.
Lock a code block via etcd.
I.e. only one client is supposed to run a block at a time.
key
The key to use for locking (will become a value key)
ttl
Optional time to live of the key (recommended to prevent deadlocks in case of a major failure)
block
The code block requiring cluster-wide synchronization
returns
result of the block

def transformValue(key: String, transformation: (String) ⇒ String): Future[String]

Perform an atomic transformation of a value node.
Perform an atomic transformation of a value node.
key
The key of the node to transform
transformation
The transformation (might be called multiple times, depending how many other clients are trying to do this)
returns
The value after the transformation
def tryLock[T](key: String, ttl: Option[Long])(block: ⇒ T): Future[(Long, Option[Try[T]])]

Try to run a code block with a lock.
Try to run a code block with a lock.
I.e. only one client is supposed to run a block at a time. If another client is currently holding the lock, the block is not executed.
key
The key to use for locking (will become a value key)
ttl
Optional time to live of the key (recommended to prevent deadlocks in case of a major failure)
block
The code block requiring cluster-wide synchronization
returns
etcd index of the try, result of the block
def tryTransformValue(key: String, transformation: (String) ⇒ String): Future[(Boolean, String)]

Tries an atomic transformation of a value node.
Tries an atomic transformation of a value node.
The transformation is only tried once and might fail.
key
The key of the node to transform
transformation
The transformation
returns
The current value of the and if the transformation was successful
