Point in Time API

Use the Point in Time (PIT) API to manage PITs.

Create a PIT

Introduced 2.4

Creates a PIT. The keep_alive query parameter is required; it specifies how long to keep a PIT.

Path and HTTP methods

POST /<target_indexes>/_search/point_in_time?keep_alive=1h&routing=&expand_wildcards=&preference=

Sample request

Response fields

Extend a PIT time

You can extend a PIT time by providing a keep_alive parameter in the pit object when you perform a search:

GET /_search
{
  "size": 10000,
  "query": {
    "match" : {
      "user.id" : "elkbee"
    }
  },
  "pit": {
    "id":  "46ToAwMDaWR5BXV1aWQyKwZub2RlXzMAAAAAAAAAACoBYwADaWR4BXV1aWQxAgZub2RlXzEAAAAAAAAAAAEBYQADaWR5BXV1aWQyKgZub2RlXzIAAAAAAAAAAAwBYgACBXV1aWQyAAAFdXVpZDEAAQltYXRjaF9hbGw_gAAAAA==", 
    "keep_alive": "100m"
  },
  "sort": [ 
    {"@timestamp": {"order": "asc", "format": "strict_date_optional_time_nanos"}},
    {"_shard_doc": "desc"}
  ],
  "search_after": [  
    "2021-05-20T05:30:04.832Z"
  ]
}

The keep_alive parameter in a search request is optional. It specifies the amount by which to extend the time to keep a PIT.

List all PITs

Introduced 2.4

Returns all PITs in the OpenSearch cluster.

Cross-cluster behavior

The List All PITs API returns only local PITs or mixed PITs (PITs created in both local and remote clusters). It does not return fully remote PITs.

Sample request

GET /_search/point_in_time/_all

Sample response

{
    "pits": [
        {
            "pit_id": "o463QQEPbXktaW5kZXgtMDAwMDAxFnNOWU43ckt3U3IyaFVpbGE1UWEtMncAFjFyeXBsRGJmVFM2RTB6eVg1aVVqQncAAAAAAAAAAAEWcDVrM3ZIX0pRNS1XejE5YXRPRFhzUQEWc05ZTjdyS3dTcjJoVWlsYTVRYS0ydwAA",
            "creation_time": 1658146048666,
            "keep_alive": 6000000
        },
        {
            "pit_id": "o463QQEPbXktaW5kZXgtMDAwMDAxFnNOWU43ckt3U3IyaFVpbGE1UWEtMncAFjFyeXBsRGJmVFM2RTB6eVg1aVVqQncAAAAAAAAAAAIWcDVrM3ZIX0pRNS1XejE5YXRPRFhzUQEWc05ZTjdyS3dTcjJoVWlsYTVRYS0ydwAA",
            "creation_time": 1658146050064,
            "keep_alive": 6000000
        }
    ]
}

Response fields

Each PIT object contains the following fields.

Delete PITs

Introduced 2.4

Deletes one, several, or all PITs. PITs are automatically deleted when the keep_alive time period elapses. However, to deallocate resources, you can delete a PIT using the Delete PIT API. The Delete PIT API supports deleting a list of PITs by ID or deleting all PITs at once.

Cross-cluster behavior

The Delete PITs by ID API fully supports deleting cross-cluster PITs.

The Delete All PITs API deletes only local PITs or mixed PITs (PITs created in both local and remote clusters). It does not delete fully remote PITs.

Sample Request: Delete all PITs

DELETE /_search/point_in_time/_all

If you want to delete one or several PITs, specify their PIT IDs in the request body.

Request fields

Sample request: Delete PITs by ID

DELETE /_search/point_in_time
{
    "pit_id": [
        "o463QQEPbXktaW5kZXgtMDAwMDAxFkhGN09fMVlPUkVPLXh6MUExZ1hpaEEAFjBGbmVEZHdGU1EtaFhhUFc4ZkR5cWcAAAAAAAAAAAEWaXBPNVJtZEhTZDZXTWFFR05waXdWZwEWSEY3T18xWU9SRU8teHoxQTFnWGloQQAA",

    ]
}

Sample response

For each PIT, the response contains a JSON object with a PIT ID and a successful field that specifies whether the deletion was successful. Partial failures are treated as failures.

{
    "pits": [
        {
            "successful": true,
            "pit_id": "o463QQEPbXktaW5kZXgtMDAwMDAxFkhGN09fMVlPUkVPLXh6MUExZ1hpaEEAFjBGbmVEZHdGU1EtaFhhUFc4ZkR5cWcAAAAAAAAAAAEWaXBPNVJtZEhTZDZXTWFFR05waXdWZwEWSEY3T18xWU9SRU8teHoxQTFnWGloQQAA"
        },
        {
            "successful": false,
            "pit_id": "o463QQEPbXktaW5kZXgtMDAwMDAxFkhGN09fMVlPUkVPLXh6MUExZ1hpaEEAFjBGbmVEZHdGU1EtaFhhUFc4ZkR5cWcAAAAAAAAAAAIWaXBPNVJtZEhTZDZXTWFFR05waXdWZwEWSEY3T18xWU9SRU8teHoxQTFnWGloQQAA"
        }
    ]
}

Response fields

PIT segments

Introduced 2.4

Similarly to the CAT Segments API, the PIT Segments API provides low-level information about the disk utilization of a PIT by describing its Lucene segments. The PIT Segments API supports listing segment information of a specific PIT by ID or of all PITs at once.

Sample request: PIT segments of all PITs

GET /_cat/pit_segments/_all

If you want to list segments for one or several PITs, specify their PIT IDs in the request body.

Request fields

Sample request: PIT segments of PITs by ID

GET /_cat/pit_segments
{
    "pit_id": [
        "o463QQEPbXktaW5kZXgtMDAwMDAxFkhGN09fMVlPUkVPLXh6MUExZ1hpaEEAFjBGbmVEZHdGU1EtaFhhUFc4ZkR5cWcAAAAAAAAAAAEWaXBPNVJtZEhTZDZXTWFFR05waXdWZwEWSEY3T18xWU9SRU8teHoxQTFnWGloQQAA",
