      • updateByQueryRetryingOnConflict

        public static void updateByQueryRetryingOnConflict​(co.elastic.clients.elasticsearch.core.UpdateByQueryRequest request,
                                                   int retries)
                                            throws java.io.IOException
        Executes a ElasticsearchClient.updateByQuery(UpdateByQueryRequest), retrying the operation the specified number of times in case of conflict response (409).

        A conflict response is assumed to happen if the call throws a ResponseException with status code 409 or if the response indicates it has conflicts.

        To reduce conflict probability, it is recommended to use a request with UpdateByQueryRequest.conflicts() set to Conflicts.Proceed and refresh enabled.

        Parameters:
        request - the updateByQuery request.
        retries - the maximum number of retries.
        Throws:
        java.io.IOException - the exception thrown by the last try of executing the updateByQuery, or if the maximum number of retries is reached and conflicts occurred, although the updateByQuery did not throw it on the last attempt.
        Since:
        16.1.0
