Defaults to `false`. [[java-rest-high-x-pack-machine-learning-delete-datafeed-response]] ==== Delete Datafeed Response The returned `AcknowledgedResponse` object indicates the acknowledgement of the request: ["source","java",subs="attributes,callouts,macros"] --------------------------------------------------- include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-delete-ml-datafeed-response] --------------------------------------------------- <1> `isAcknowledged` was the deletion request acknowledged or not [[java-rest-high-x-pack-machine-learning-delete-datafeed-async]] ==== Delete Datafeed Asynchronously This request can also be made asynchronously. ["source","java",subs="attributes,callouts,macros"] --------------------------------------------------- include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-delete-ml-datafeed-request-async] --------------------------------------------------- <1> The `DeleteDatafeedRequest` to execute and the `ActionListener` to alert on completion or error.
