Event Archiver

Sometimes, it’s required to keep full history of events. However, it’s inefficient to have a very large database for realtime operations. Therefore, a special DBEventArchiver tool is provided to reliably transfer events into data warehouse.

The interface is the same as for ReliableReceiver, except addition configuration option: history_table.

DBEventArchiver expects CCM to have Database connection named evtdhw to be configured.


const DBEventArchiver = require( 'futoin-eventstream/DBEventArchiver' );

// Initialize CCM & DWH connection
const ccm = new AdvancedCCM();
DBAutoConfig( as, ccm, { evtdwh: {} } );

// Initialize and start DB Event Archiver
const archiver = new DBEventArchiver(ccm);
archiver.start( endpoint, credentials );
