Abstract
A selective data restoration technique is disclosed. A request to recover data in a dataset is received along with an identifier of a particular portion of the data to be recovered. The request may specify a time that indicates a desired recovery state (e.g., recover the values as they were at the time). Change data is determined for the specified time. For example, data stream filters generate recovery data by applying filters (e.g., keys) to a time window batch of the stream data. The stream data may correspond to changes to a data set, and the recovery data may correspond to only a portion of the dataset (e.g., a portion of a table). The system performs a recovery action, based on the recovery data, using the recovery data to automatically restore data in a data store, or providing the recovery date to the requesting entity, for example.
