The file input is made for continuous monitoring of a log file which is exactly what you're looking for. Use the jdbc input for reading from your relational database. It can be configured to run on a schedule. There are a couple of ways to avoid duplicate insertions from the database. At least one of the methods is described in the plugin documentation. ---
