Bug description:
The attached script is creating a log with ~49k events.
In the constructor of ZeitgeistEngine we need to search for the minimum and
maximum event id. In the script I'm doing two different ways of getting these
values:
Our current query:
SELECT MIN(id), MAX(id) FROM event
-> this is not using the event index, and takes about 0.096 secunds for me
do the same in two queries:
SELECT MIN(id) FROM event+SELECT MAX(id) FROM event
-> both queries are using the index, and together they take about 0.003 for me
I suggest changing the one query into two to get some speedups.
