Main changes: 1) Convert SeekableStreamIndexTaskClient to an interface, move old code to SeekableStreamIndexTaskClientSyncImpl, and add new implementation SeekableStreamIndexTaskClientAsyncImpl that uses ServiceClient. 2) Add "chatAsync" parameter to seekable stream supervisors that causes the supervisor to use an async task client. 3) In SeekableStreamSupervisor.discoverTasks, adjust logic to avoid making blocking RPC calls in workerExec threads. 4) In SeekableStreamSupervisor generally, switch from Futures.successfulAsList to FutureUtils.coalesce, so we can better capture the errors that occurred with contacting individual tasks. Other, related changes: 1) Add ServiceRetryPolicy.retryNotAvailable, which controls whether ServiceClient retries unavailable services. Useful since we do not want to retry calls unavailable tasks within the service client. (The supervisor does its own higher-level retries.) 2) Add FutureUtils.transformAsync, a more lambda friendly version of Futures.transform(f, AsyncFunction). 3) Add FutureUtils.coalesce. Similar to Futures.successfulAsList, but returns Either instead of using null on error. 4) Add JacksonUtils.readValue overloads for JavaType and TypeReference. |
