> When writing Flink tests, I could reduce the latency of my 'waitForDone' calls by writing my own looping retry-sleep logic than rely on `TableResult.getJobClient().get().getJobExecutionResult(...)`.  This is because `[MiniCluster|https://github.com/apache/flink/blob/47ca19a74e11c72842124852875262959477c459/flink-runtime/src/main/java/org/apache/flink/runtime/minicluster/MiniCluster.java#L338]` uses [RpcGatewayRetriever|https://github.com/apache/flink/blob/8674b69964eae50cad024f2c5caf92a71bf21a09/flink-runtime/src/main/java/org/apache/flink/runtime/webmonitor/retriever/impl/RpcGatewayRetriever.java] which has a fixed 20ms retry.
>  
> For a complex test, this can save 50ms-100ms per test run.
>  
> An easy fix is to change this to an retry with exponential backoff.  This reduces the impact
