Pending cluster tasks
editPending cluster tasks
editThe pending cluster tasks API returns a list of any cluster-level changes (e.g. create index, update mapping, allocate or fail shard) which have not yet been executed.
$ curl -XGET 'http://localhost:9200/_cluster/pending_tasks'
Usually this will return an empty list as cluster-level changes are usually fast. However if there are tasks queued up, the output will look something like this:
{
"tasks": [
{
"insert_order": 101,
"priority": "URGENT",
"source": "create-index [foo_9], cause [api]",
"time_in_queue_millis": 86,
"time_in_queue": "86ms"
},
{
"insert_order": 46,
"priority": "HIGH",
"source": "shard-started ([foo_2][1], node[tMTocMvQQgGCkj7QDHl3OA], [P], s[INITIALIZING]), reason [after recovery from shard_store]",
"time_in_queue_millis": 842,
"time_in_queue": "842ms"
},
{
