maciej / etcd-client Goto Github PK

I'm looking for a way to use etcd from Scala, and just scouting the options.

I call the get method of the client, if the node exist, it works fine, but if the node doesn't exist, it return the following error:

[error]   ! return in success
[error]    null (EtcdMessage.scala:52)
[error] me.maciejb.etcd.client.EtcdError$.apply(EtcdMessage.scala:52)
[error] me.maciejb.etcd.client.impl.EtcdJsonProtocol$$anon$1.read(EtcdJsonProtocol.scala:30)
[error] me.maciejb.etcd.client.impl.EtcdJsonProtocol$$anon$1.read(EtcdJsonProtocol.scala:15)
[error] spray.json.JsValue.convertTo(JsValue.scala:31)
[error] me.maciejb.etcd.client.impl.EtcdClientImpl$$anonfun$3$$anonfun$apply$4.apply(EtcdClientImpl.scala:127)
[error] me.maciejb.etcd.client.impl.EtcdClientImpl$$anonfun$3$$anonfun$apply$4.apply(EtcdClientImpl.scala:124)

KillSwitch got introduced in Akka 2.4.3 and at first glance it seems to provide the same functionality as FlowBreaker. Investigate it:
http://doc.akka.io/japi/akka/2.4.3/akka/stream/KillSwitch.html

Should contain an SBT code snippet with dependency

Currently the project depends on akka-http-experimental. I'd assume akka-http-core should be a satisfactory dependency, though.

• Add docker-compose.yml with etcd container setup
• Test if etcd is discovered when used with Docker Machine (like on OSX)
• Use in .travis.yml. See this document for how to set it up.

How to instantiate a EtcdClient, feature basic interactions with etcd.

I'm using a 3rd party etcd provider and their instances require http auth. Unless I'm missing something in ClientConnectionSettings, I don't believe this is currently possible with your client library (though I really like it otherwise so don't want to switch to another). I was thinking of overriding call in EtcdClientImpl but it seems a bit too abstracted to be simply extended since this is a private method & the class is this impl class is instantiated explicitly in the client factory method. For now I will probably fork & try to add this feature unobtrusively, will be happy to submit a PR.

In EtcdClientImpl#33

Is there any reason why you don't use a connection pool?
