You must provide the `seq_no` and `primary_term` parameters. #### Request ```json PUT _plugins/_rollup/jobs/ // Create PUT _plugins/_rollup/jobs/?if_seq_no=1&if_primary_term=1 // Update { "rollup": { "source_index": "nyc-taxi-data", "target_index": "rollup-nyc-taxi-data", "schedule": { "interval": { "period": 1, "unit": "Days" } }, "description": "Example rollup job", "enabled": true, "page_size": 200, "delay": 0, "roles": [ "rollup_all", "nyc_taxi_all", "example_rollup_index_all" ], "continuous": false, "dimensions": { "date_histogram": { "source_field": "tpep_pickup_datetime", "fixed_interval": "1h", "timezone": "America/Los_Angeles" }, "terms": { "source_field": "PULocationID" }, "metrics": [ { "source_field": "passenger_count", "metrics": [ { "avg": {} }, { "sum": {} }, { "max": {} }, { "min": {} }, { "value_count": {} } ] } ] } } } ``` You can specify the following options. Options | Description | Type | Required :--- | :--- |:--- |:--- | `source_index` | The name of the detector. | String | Yes `target_index` | Specify the target index that the rolled up data is ingested into. You can either create a new target index or use an existing index. The target index cannot be a combination of raw and rolled up data. This field supports dynamically generated index names like {% raw %}`rollup_{{ctx.source_index}}`{% endraw %}, where `source_index` cannot contain wildcards. | String | Yes `schedule` | Schedule of the index rollup job which can be an interval or a cron expression. | Object | Yes `schedule.interval` | Specify the frequency of execution of the rollup job. | Object | No `schedule.interval.start_time` | Start time of the interval. | Timestamp | Yes `schedule.interval.period` | Define the interval period. | String | Yes `schedule.interval.unit` | Specify the time unit of the interval. | String | Yes `schedule.interval.cron` | Optionally, specify a cron expression to define therollup frequency. | List | No `schedule.interval.cron.expression` | Specify a Unix cron expression. | String | Yes `schedule.interval.cron.timezone` | Specify timezones as defined by the IANA Time Zone Database. Defaults to UTC. | String | No `description` | Optionally, describe the rollup job. | String | No `enabled` | When true, the index rollup job is scheduled. Default is true. | Boolean | Yes `continuous` | Specify whether or not the index rollup job continuously rolls up data forever or just executes over the current data set once and stops. Default is false. | Boolean | Yes `error_notification` | Set up a Mustache message template sent for error notifications. For example, if an index rollup job fails, the system sends a message to a Slack channel. | Object | No `page_size` | Specify the number of buckets to paginate through at a time while rolling up. | Number | Yes `delay` | The number of milliseconds to delay execution of the index rollup job. | Long | No `dimensions` | Specify aggregations to create dimensions for the roll up time window. | Object | Yes `dimensions.date_histogram` | Specify either fixed_interval or calendar_interval, but not both. Either one limits what you can query in the target index. | Object | No `dimensions.date_histogram.fixed_interval` | Specify the fixed interval for aggregations in milliseconds, seconds, minutes, hours, or days. | String | No `dimensions.date_histogram.calendar_interval` | Specify the calendar interval for aggregations in minutes, hours, days, weeks, months, quarters, or years. | String | No `dimensions.date_histogram.field` | Specify the date field used in date histogram aggregation. | String | No `dimensions.date_histogram.timezone` | Specify the timezones as defined by the IANA Time Zone Database. The default is UTC. | String | No `dimensions.terms` | Specify the term aggregations that you want to roll up. | Object | No `dimensions.terms.fields` | Specify terms aggregation for compatible fields. | Object | No `dimensions.histogram` | Specify the histogram aggregations that you want to roll up. | Object | No `dimensions.histogram.field` | Add a field for histogram aggregations. | String | Yes `dimensions.histogram.interval` | Specify the histogram aggregation interval for the field. | Long | Yes `dimensions.metrics` | Specify a list of objects that represent the fields and metrics that you want to calculate. | Nested object | No `dimensions.metrics.field` | Specify the field that you want to perform metric aggregations on. | String | No `dimensions.metrics.field.metrics` | Specify the metric aggregations you want to calculate for the field. | Multiple strings | No #### Sample response ```json { "_id": "rollup_id", "_seqNo": 1, "_primaryTerm": 1, "rollup": { ... } } ``` ## Get an index rollup job Introduced 1.0 {: .label .label-purple } Returns all information about an index rollup job based on the `rollup_id`. #### Request ```json GET _plugins/_rollup/jobs/ ``` #### Sample response ```json { "_id": "my_rollup", "_seqNo": 1, "_primaryTerm": 1, "rollup": { ... } } ``` --- ## Delete an index rollup job Introduced 1.0 {: .label .label-purple } Deletes an index rollup job based on the `rollup_id`. #### Request ```json DELETE _plugins/_rollup/jobs/ ``` #### Sample response ```json 200 OK ``` --- ## Start or stop an index rollup job Introduced 1.0 {: .label .label-purple } Start or stop an index rollup job. #### Request ```json POST _plugins/_rollup/jobs//_start POST _plugins/_rollup/jobs//_stop ``` #### Sample response ```json 200 OK ``` --- ## Explain an index rollup job Introduced 1.0 {: .label .label-purple } Returns detailed metadata information about the index rollup job and its current progress. #### Request ```json GET _plugins/_rollup/jobs//_explain ``` #### Sample response ```json { "example_rollup": { "rollup_id": "example_rollup", "last_updated_time": 1602014281, "continuous": { "next_window_start_time": 1602055591, "next_window_end_time": 1602075591 }, "status": "running", "failure_reason": null, "stats": { "pages_processed": 342, "documents_processed": 489359, "rollups_indexed": 3420, "index_time_in_ms": 30495, "search_time_in_ms": 584922 } } } ```
