Reindex to data streams

[carrot (Steve Malenfant)]

I'm using the following to reindex to a data stream, although it completes right way... The source index has 262394 documents.

POST _reindex
{
  "source": {
    "index": "syslog-prod-2021.09.07"
  },
  "dest": {
    "index": "syslog-prod",
    "op_type": "create"
  }
}

Results:

{
  "took" : 3,
  "timed_out" : false,
  "total" : 0,
  "updated" : 0,
  "created" : 0,
  "deleted" : 0,
  "batches" : 0,
  "version_conflicts" : 0,
  "noops" : 0,
  "retries" : {
    "bulk" : 0,
    "search" : 0
  },
  "throttled_millis" : 0,
  "requests_per_second" : -1.0,
  "throttled_until_millis" : 0,
  "failures" : [ ]
}

And the logs:

[2022-09-06T18:02:38,442][INFO ][org.elasticsearch.tasks.LoggingTaskListener] [instance-0000000103] 23729349 finished with response BulkByScrollResponse[took=3.7ms,timed_out=false,sliceId=null,updated=0,created=0,deleted=0,batches=0,versionConflicts=0,noops=0,retries=0,throttledUntil=0s,bulk_failures=[],search_failures=[]]

I can reindex no problem with other indexes (not data streams).

Elastic version is 7.13.4

Thanks,

Fixed. The index was frozen.
