Abstract
The present disclosure provides techniques and solutions for determining whether a particular value is in a dataset using summary information. A sorted set of unique values is received. The sorted set of unique values includes gaps between at least certain values. The gaps are determined, and the set of unique values is represented as a gap filter. The gap filter includes a starting value of the set of unique values, a set of gap lengths, and identifiers indicating a number of unique values between respective gaps. The gap filter serves as summary information that can be used to determine whether a value be present in the dataset. In at least some cases, the use of the summary information may provide false positive results. The representation of the gap filter can be modified to improve its compressibility, but may increase the number of false positives produced by the gap filter.
