Design decisions

1. The app exploits the fail-fast methodology.
2. Streams are used to minimize a memory footprint.
3. Pipelines concurrency pattern is utilized to empower the code readability and manageability.
4. App logs to STDERR to facilitate log management (https://12factor.net/logs) and to separate logs from normal output.

Possible future improvements

1. Parse STDIN instead of command line to overcome various OS limitations for command line environments.
