How to use tasks api in 8+ client in java?
I've seen ElasticSearchTasks client which provides functionality to list/cancel/get tasks. But how to send a task?
Previously we could just use `submitUpdateByQueryTask` method of `restHighLevelClient` which returns taskId.
But how to send a long running request and get taskId back now? (similar to wait\_for\_completion=false)

Hello and welcome! Those you're referring to are 2 different APIs, one is [Task management](https://www.elastic.co/guide/en/elasticsearch/reference/current/tasks.html) (to check on running tasks) and the other is [Update by Query](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html). An example of how to call Update by Query in the new client:
```java
UpdateByQueryResponse ubqRes = esClient.updateByQuery(u -> u
.waitForCompletion(false)
.index("my-index-000001")
.conflicts(Conflicts.Proceed)
.query(q -> q
.term(t -> t
.field("user.id")
.value("kimchy")
)
)
);
```
it returns an object that (in this case since `wait_for_completion` is false) will contain the task Id, which can then be checked by using a Get Task request:
```java
GetTasksResponse taskInfo = esClient.tasks().get(g -> g.taskId(ubqRes.task()));
```
