Decanter dispatcher. 1.2.19. JDBC The Decanter JDBC collector periodically executes a query on a database and sends the query result to the dispatcher. Apache Karaf Decanter 2.x - Documentation - 19 connect to the database. You can create this datasource using the Karaf jdbc:create command (provided by the jdbc feature). • the query property contains the SQL query to perform on the database and retrieve from the collectors) into a database. The Decanter JDBC appender transforms the data as a json string. The appender stores the json string and the timestamp into the database. The decanter-appender-jdbc
