Adrian Elias Bratlann

During the month, contributed a performance optimization to the OSGeo/gdal repository by enhancing the OCI driver’s SELECT operations. Developed a configurable prefetch mechanism in C++ that introduces the OCI_PREFETCH_ROWS option, defaulting to 1000 rows, to address latency issues in high-latency environments. This adjustment reduced round-trip delays by enabling bulk row retrieval instead of the previous row-by-row fetching, resulting in more stable throughput and improved responsiveness for both interactive and batch queries. The work demonstrated strong skills in C++ programming, database management, and performance optimization, directly addressing production workload impediments and closing a related issue in the project.

Month: 2026-05 — Delivered a performance-focused optimization for the OSGeo/gdal OCI driver by introducing a configurable prefetch mechanism for SELECT operations. The OCI driver now supports an OCI_PREFETCH_ROWS option with a default of 1000 rows, reducing round-trip latency and avoiding slow row-by-row fetches in high-latency environments. This change stabilizes throughput and improves interactive and batch query performance across latency profiles commonly seen in production. The work is backed by the commit that updates OCI_ATTR_PREFETCH_ROWS and sets a sane default, and closes related workload impediments (see commit reference).
