Developed a key feature for the area9innovation/flow9 repository, enabling configurable JVM heap size in the Flowc1 script through the FLOWC_XMX environment variable. This enhancement allows users to tailor Java memory allocation to their specific needs, improving resource management for various workflows. The implementation leveraged Bash scripting and focused on robust shell practices by introducing strict error handling with set -euo pipefail, ensuring that scripts fail fast on errors or undefined variables. By combining environment variable management with JVM configuration, the work improved the stability and reliability of flow execution, supporting safer and more predictable deployments within the project.
