We had some slow running queries and I was trying to use the “Logs & Queries” dashboard for some insights. It lists long durations for very simple queries in “Currently running queries”, but these do not match the “Query statistics”.
For testing I cleared the statistics, refreshed our app and then the dashboard and saw this Does “Duration” mean the duration of a client connection? What does “Query” mean in this context then?

Duration is the time a query has been executing. It seems like that either you have a very large table without any indexes, or maybe a poorly structured.
The best thing to do is to get the exact query that is taking very long time to complete and then do an
EXPLAINfor that query, that way you will be able to see the query plan and try to identify where you might be able to add some indexes to improve the performance or try to limit the results for example.
Feel free to share the complete query here and I could also have a look.
