I have an index with 130,000 documents each about 1-3Mb geo\_shape data. I'm trying to map them to a different index (New index only has an greater number of shards).

When I run the following reindex, it only runs for the first 1000 documents and then stops. Is there a way to extend the reindex to all documents in the index?

```
POST _reindex
{
  "source": {
    "index": "old_index"
  },
  "dest": {
    "index": "new_index"
  }
}

```

Thank you for your help!

No idea. Anything in logs?  
Once it's stopped can you run run a hot\_threads API call?  
Is the task still running?

Hi David

The task exits without and there is nothing of note either in the logs or hot\_threads api.

I had decided to do the reindex in chunks based on a range over a unique field.

But we modified our underlying data so a reindex isn't of use to us anymore.

Thanks for replying.

Cheers
