// create client
Client client = Client.builder().endpoints("http://localhost:2379").build();
KV kvClient = client.getKVClient();
ByteSequence key = ByteSequence.fromString("test_key");
ByteSequence value = ByteSequence.fromString("test_value");
// put the key-value
kvClient.put(key, value).get();
// get the CompletableFuture
CompletableFuture<GetResponse> getFuture = kvClient.get(key);
// get the value from CompletableFuture
GetResponse response = getFuture.get();
// delete the key
kvClient.delete(key).get();For full etcd v3 API, plesase refer to API_Reference.
The examples are standalone projects that show usage of jetcd.
The project follows Semantic Versioning.
The current major version is zero (0.y.z). Anything may change at any time. The public API should not be considered stable.
The project is to be tested against a three node etcd setup, which automatically launched via Testcontainers framework.
