this is only a small log file 😄 only a subset of all available sensors. We get old data as csv, and new data from a stream. Both should be stored in a db. For csv batch import we use sql copy
https://www.postgresql.org/docs/current/sql-copy.html. Problem is streaming import, as we need to create the dao class/or a use a method with all values. Or is there any workaround using multiple arrays? 😄
