Over four months, contributed to nebulastream/nebulastream by delivering four features and resolving one bug, focusing on backend reliability and developer experience. Enhanced the TCPSource component with configurable connection timeouts and robust error handling using C++ and system programming techniques, improving data pipeline stability and observability. Improved SQL parsing by enabling support for negative typed float literals in WHERE predicates, backed by regression tests to ensure query accuracy. Addressed Docker build consistency by correcting ARG scoping across Dockerfiles and updated documentation to clarify ARM image workflows. Work emphasized maintainability, testability, and clear configuration management, leveraging C++, Docker, and SQL expertise throughout.

Dec 1, 2024December 2024 monthly summary for nebulastream/nebulastream: Delivered reliability-focused enhancements to the TCPSource by introducing a configurable connection timeout and refactoring the connection logic for better robustness and error reporting. The changes enable operators to tune latency versus reliability (default timeout 10s, minimum 1s), reduce hang conditions, and provide clearer diagnostics for source connection issues.
