Client libraries support matrix for etcd
As etcd features support is really uneven between client libraries, a compatibility matrix can be important. We will consider in detail only the features of clients supporting the v2 API. Clients still supporting the v1 API only are listed below.
v1-only clients
Clients supporting only the API version 1
- justinsb/jetcd Java
- transitorykris/etcd-py Python
- russellhaering/txetcd Python
- iconara/etcd-rb Ruby
- jpfuentes2/etcd-ruby Ruby
- aterreno/etcd-clojure Clojure
- marshall-lee/etcd.erl Erlang
v2 clients
The v2 API has a lot of features, we will categorize them in a few categories:
- HTTPS Auth: Support for SSL-certificate based authentication
- Reconnect: If the client is able to reconnect automatically to another server if one fails.
- Mod/Lock: Support for the locking module
- Mod/Leader: Support for the leader election module
- GET,PUT,POST,DEL Features: Support for all the modifiers when calling the etcd server with said HTTP method.
