run setup.sh

run start_webservice.sh

This starts the local EventStore webservice. The service has to be running for the synchronizer to work.

Check if the webservice is running before starting the synchronization service.

run start_sync.sh

The first synchronizer service in the network initialized a udp server. All synchronizers started later will find the server via udp broadcast. The server maintains a list of all known clients. TODO: Whenever a client connects to the server, the EventStore status hash is fetched via web api. TODO: Whenever a client is out of sync with the server there will be a two way sync.

The server stops after 20s and waits for another sync to be started (eg via cron-job) TODO: is this good?
