The current version of the dataset can be provided to detect concurrent modifications. This endpoint requires any of the following permissions: `security_monitoring_rules_write``security_monitoring_dataset_write` OAuth apps require the `security_monitoring_rules_write` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#security-monitoring) to access this endpoint. ### Arguments #### Path Parameters | Name | Type | Description | | ---------------------------- | ------ | ------------------------ | | dataset_id [*required*] | string | The UUID of the dataset. | ### Request #### Body Data (required) {% tab title="Model" %} | Parent field | Field | Type | Description | | ------------ | ----------------------------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | data [*required*] | object | The data wrapper of a dataset update request. | | data | attributes [*required*] | object | The attributes of a dataset create or update request. | | attributes | definition [*required*] | object | The definition of the dataset. The shape depends on the value of `data_source`. Use `reference_table` or `managed_resource` for a referential dataset, or one of the event platform sources (for example `logs`, `audit`, `events`, `spans`, `rum`) for an event platform dataset. | | definition | columns | [object] | For event platform datasets, the list of columns exposed by the dataset. | | columns | column [*required*] | string | The name of the column. | | columns | type [*required*] | string | The type of the column value. | | definition | data_source [*required*] | string | The data source backing this dataset definition. | | definition | indexes | [string] | For event platform datasets, the list of indexes to query. | | definition | name [*required*] | string | The unique name of the dataset. Must start with a lowercase letter and contain only lowercase letters, digits, and underscores (max 255 characters). | | definition | query_filter | string | For referential datasets, an optional filter expression applied to the table. | | definition | search | object | The search clause applied to an event platform dataset. | | search | query [*required*] | string | The search query expression. | | definition | storage | string | Storage tier the dataset reads from. Applies to event platform datasets. | | definition | table_name | string | For referential datasets, the name of the underlying table. | | definition | time_window | object | An optional time window that overrides the default query time range. | | time_window | from | int64 | Inclusive start of the time window, in milliseconds since the Unix epoch. | | time_window | to | int64 | Exclusive end of the time window, in milliseconds since the Unix epoch. | | attributes | description | string | The description of the dataset. Maximum 255 characters. | | attributes | version | int64 | The expected current version of the dataset for optimistic concurrency control on updates. If the dataset's current version does not match, the request is rejected with a 409 Conflict. | | data | type [*required*] | enum | The type of resource for a dataset update request. Allowed enum values: `datasetUpdate` | {% /tab %} {% tab title="Example" %} ```json { "data": { "attributes": { "definition": { "columns": [ { "column": "message", "type": "string" } ], "data_source":
