Hi,  
Would appreciate help with the following conundrum:

I have an index with time-series events; here are some document examples:

```auto
{ "timestamp": 1, "status": "running" }
{ "timestamp": 2, "status": "running" }
{ "timestamp": 3, "status": "blocked" }
{ "timestamp": 4, "status": "blocked" }
{ "timestamp": 5 "status": "blocked" }
{ "timestamp": 10, "status": "blocked" }
{ "timestamp": 11, "status": "blocked" }
{ "timestamp": 12, "status": "running" }
{ "timestamp": 13, "status": "running" }

```

I need to find sequences of chronologically contiguous documents **with the same status** , whereby a timestamp gap (no matter it's size) or a different status, closes a bucket and opens a new one in its stead.  
An expected output would look like:

```auto
{
  "buckets": [
    {
      "start": 1,
      "end": 2,
      "status": "running",
      "count": 2
    },
    {
      "start": 3,
      "end": 5,
      "status": "blocked",
      "count": 3
    },
    {
      "start": 1,
      "end": 2,
      "status": "running"
    },
    {
      "start": 10,
      "end": 11,
      "status": "blocked"
    },
    {
      "start": 12,
      "end": 13,
      "status": "running"
    }
  ]
}

```

Any help would be greatly appreciated
