StreamMachine Archiver

This is an experiment that may eventually become part of StreamMachine's core functionality.

Archiver connects to StreamMachine master as a slave, but instead of serving data up to clients it writes HLS segments to disk or S3.

So far, waveform data is kept in memory and is regenerated on restart.

While running, StreamMachine Archiver can be found at http://localhost:9000⁽¹⁾.
