描述

The get task API (e.g. GET _tasks/lOHn4ATPST6LfKCW6m539w:517820) should include an estimated time of completion where applicable.

Specifically when using the reindex API, I had to write myself a basic tool some time ago to estimate when the task would be completed using the total, created, updated, start_time_in_millis, and running_time_in_nanos properties. (Although I believe in cases where the reindex operation omits some documents, this may not even be sufficient!)

It would be great if this functionality was built into this API.

研究方向: Investigate the Elasticsearch task management system, specifically the get task API implementation at `GET tasks/{taskId}`. Understand how the reindex operation tracks progress using fields like `total`, `created`, `updated`, `start time in millis`, and `running time in nanos`. Research potential algorithms like exponential moving average to estimate ETA, considering that documents may be omitted. Review existing discussions in the issue and any linked resources. Look at the `TasksClient.java` and `TransportTasksAction.java` source files for implementation details. Proposing adding an `estimated completion time` field to the task response is a starting point.
