Interface OverlordClient

All Known Implementing Classes:

OverlordClientImpl

public interface OverlordClient

High-level Overlord client. Similar to IndexingServiceClient, but backed by ServiceClient instead of DruidLeaderClient. All methods return futures, enabling asynchronous logic. If you want a synchronous response, use FutureUtils.get or FutureUtils.getUnchecked. Futures resolve to exceptions in the manner described by ServiceClient.asyncRequest(org.apache.druid.rpc.RequestBuilder, org.apache.druid.java.util.http.client.response.HttpResponseHandler<IntermediateType, FinalType>). Typically acquired via Guice, where it is registered using ServiceClientModule.
