PROFILE
Bartłomiej Ząbek
Worked on the snowflakedb/snowflake-kafka-connector repository, delivering three features over two months focused on backend and data engineering. Enhanced streaming reliability and scalability by standardizing JSON processing with the Jackson core library and resolving dependency conflicts. Improved Iceberg integration by enabling configuration through StreamingClientProperties, adding schema parsing, type mapping, and SQL generation, and reducing reflection overhead. Further advanced Iceberg schema evolution to support dynamic column type changes and preserve column comments, improving data governance and reducing downtime. Optimized integration and unit tests for faster validation and lower maintenance. Demonstrated expertise in Java, Scala, Kafka Connect, and Snowflake integration.

Dec 1, 2024In December 2024, delivered Iceberg Schema Evolution Enhancements for the snowflake-kafka-connector, enabling dynamic on-the-fly column type changes and preserving/exposing column comments during evolution. Cleaned up tests to deliver faster, more reliable validation and reduced maintenance overhead. No major bugs reported this month. Overall impact: reduces downtime during schema evolution, improves data governance through visible metadata, and accelerates downstream data-pipeline delivery. Technologies/skills demonstrated: Iceberg schema evolution, Kafka Connect integration, Java/Scala code updates, test optimization, and CI/test automation.

Nov 1, 2024Month 2024-11: Delivered two major capabilities in the snowflake-kafka-connector to improve reliability, data fidelity, and scalability of streaming workloads. Standardized JSON handling by migrating to the standard Jackson core library, replacing internal Snowflake Jackson dependencies to resolve conflicts and ensure consistent JSON processing. Enhanced Iceberg integration with configuration via StreamingClientProperties (eliminating reflection), plus Iceberg schema parsing, type mapping, and SQL generation for Iceberg tables; updated tests and dependencies to align with the new approach. Overall, these changes reduce runtime errors, improve stability, and broaden Iceberg compatibility, supporting more robust streaming analytics. Technologies demonstrated include Jackson core, Iceberg integration, StreamingClientProperties, schema parsing, type mapping, SQL generation, and test/dependency management.
