Abstract
Systems and methods are provided for tracking System Management Facility (SMF) record types using a small array. An index entry can be modified by adding an extension that tracks what record types are missing, rather than what record types are included in a particular history file. As log data comprising a plurality of history files is received, a flag bit in the header of each history file indicates that the associated history file comprises extended record types. An extension is added to each of the index entries associated with the history files that contain extended record types. Extensions may indicate record type gaps in the associated history file. Upon receiving a query for a particular record type of data stored in the data store, the extension can be utilized to determine which history files do not have the particular record type and can be skipped in the search.
