Public bug reported: 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. ** Affects: zeitgeist Importance: Undecided Status: New -- ZeitgeistEngine.__init__(): statement to get last row id is not using the index https://bugs.launchpad.net/bugs/641100 You received this bug notification because you are a member of Zeitgeist Framework Team, which is subscribed to Zeitgeist Framework.
