Claim 0:
1. A computer-implemented method comprising:
obtaining events of an event stream generated, at least in part, as a result of application programming interface (API) requests to perform read operations on data objects stored in a logical data container of a data storage service;
inputting data from at least a plurality of the events into a machine learning model, the data comprising hypertext transfer protocol (HTTP) error code values for at least some of the plurality of events, the HTTP error code values indicating respective failures to perform requested operations as a result of respective data objects not being found;
obtaining output of the machine learning model, corresponding to the data input into the machine learning model, that indicates whether a set of the events represent anomalous deletion of data in the logical data container; and
as a result of the output of the machine learning model indicating that the set of the events represent anomalous deletion of data in the logical data container, initiating a workflow to prevent permanent deletion of the data.
