Abstract
A storage control system receives a request to access target data and searches a primary metadata structure to find an associated metadata entry. The primary metadata structure comprises a log-structured merge tree comprising a first level of segments which comprises a group of segments having an associated group filter, and individual filters associated with respective segments of the group of segments. The storage control system searches the primary metadata structure by performing a lookup operation using the group filter to determine whether the associated metadata entry is potentially present in a given segment of the group of segments, and performing a lookup operation using the individual filters to identify the given segment of the group of segments which potentially includes the metadata entry, when the metadata entry is determined to be potentially present in a given segment of group of segments, using the group filter.
