> Comment mentions that finished queries will be immediately inserted into DB.
> As per code given below, for a finished query to be immediately inserted into DB, (size > maxFinishedQueries) expression should be true. Assume one query enters finishedQueries queue. (size = 1). To immediately deque this query, 1 should be greater than maxFinishedQueries. This would happen only if maxFinishedQueries is 0. However in the lens-site.xml code above, lens.server.max.finished.queries is set to 1.
> {code}
>    @Override
>     public long getDelay(TimeUnit units) {
>       int size = finishedQueries.size();
>       if (size > maxFinishedQueries) {
>         return 0;
>       } else {
>         return Integer.MAX_VALUE;
>       }
>     }
> {code}
