Latest Patents

Mostafa Mokhtar's latest patents include "Adaptive approach to lazy materialization in database scans using pushed filters." This patent discloses a method for determining whether to apply a lazy materialization technique to a query run. A data processing service receives a request to perform a query identifying a filter column and a non-filter column in a columnar database. The service accesses a first task of contiguous rows in the filter column from a cloud-based object storage. It applies a filter defined by the query to the first task and generates filter results that may include a percentage of the first task discarded and a run-time. Based on these results, the service determines a likelihood value indicating the potential performance benefit of applying the lazy materialization technique to a second task of the query.

Another notable patent is "Distinct value estimation for query planning." This invention addresses the problem of distinct value estimation, which is crucial in database technology. The technique estimates the number of distinct values in a dataset without scanning all values. It involves gathering multiple intermediate probabilistic estimates based on varying samples, plotting these estimates against sample size, fitting a function to the data points, and extrapolating to determine an overall distinct value estimate.
