--------------------------------------
Summary: Import shaded jetcd
Key: FLINK-11806
URL: https://issues.apache.org/jira/browse/FLINK-11806
Project: Flink
Issue Type: Task
Components: Runtime / Coordination
Reporter: MalcolmSanders
Assignee: MalcolmSanders
Since etcd has already provided a Java client API named
[jetcd|https://github.com/etcd-io/jetcd] to communicate with etcd server, we
need to import the maven dependency for jetcd. Like flink's curator dependency,
we should also make jetcd dependency shaded.
As I have discussed in the [design
doc|https://docs.google.com/document/d/12-gIZDuT4IOWG7gmwSqNFsOHuGlkdRHge0ahJ7M311Y/edit#heading=h.d9ptqjeg282n],
jetcd currently still lacks of high level APIs to achieve functionalities such
as LeaderLatch, SharedCount and etc. I'm cooperating with contributors from
jetcd community. Previously I've contributed a PR to enable setting namespaces
[jetcd#504|https://github.com/etcd-io/jetcd/pull/504]. There are two issues
needed to be completed:
(1) LeaderLatch API which is in discussion [
jetcd#516|https://github.com/etcd-io/jetcd/issues/516]
(2) Sequencer API to achieve SharedCount in curator which I'm working on
[jetcd#473|https://github.com/etcd-io/jetcd/issues/473]
