Build status:

Simple library to use etcd in a play application.

Usage

The current version is supposed to run with Play 2.4 or higher.

Add the following dependency to your project

libraryDependencies += "de.leanovate" %% "play-etcd-client" % "2.4.0"

The library has two main classes:

• de.leanovate.play.etcd.EtcdClient
  • Encapsulates low level interactions with the etcd cluster.
  • getNode: Get value or directory node
  • createValue: Create a value node in a directory (with auto-generated key)
  • updateValue: Create or update a value node
  • deleteValue: Delete a value node
  • updateDir: Create or update a directory node
  • deleteDir: Delete directory node
• de.leanovate.play.etcd.EtcdOperation
  • Implements higher level usecases one might realize with an etcd cluster.
  • getValues: Convenient method to get values from value or directory nodes
  • transformValue / tryTransformValue: Perform an atomic transformation on a value node
  • enqueueValue / dequeueValue: Use a directory node as queue
  • lock / tryLock: Perform a cluster-wide synchronization of code block
