force cache update instead of rebuild?

Postby kavonr » Sun Oct 31, 2010 10:38 am

Is there anyway to force the cache update process instead of the rebuild? Version 3.07.6 beta. I did manual housekeeping and selected update but it ignores me and rebuilds. Even a kludgy manual process would be great. I'm aware that it's more efficient to rebuild but I cannot leave my system on long enough for rebuild to complete. I would have hoped if I explicitly told it to update that it would do so.

It seems clear that when I interrupt the rebuild process at 15% cache status and then start again later it seems to be rebuilding rows that were already complete even though no new data was loaded. Where I live the power goes out for 5 hours every night and I need the computer for other uses in the morning. I'm not going to buy a generator just to rebuild my cache. I dont care if it takes 3 times longer as long as I can do it in steps.

It looks like about 30 hours at the rate it's been going and I loaded only half of my data. For the record I am very experienced at database performance and tuning and have done all I can with the equipment that is available (dedicated data disk, separate logs, changes to the .conf file etc.). I even built a parallel OS installation just to clear out the junk. I suppose I could clear out the DB and load small amounts (5% of total DB size will prevent cache rebuild?) but I'd rather pull my hair out first 8-) .

If I don't rebuild cache, what is the effect? Will it rebuild individual players as I access their data (making it very slow) or will I get incorrect information?

Da old goat (new to PT3).

If you have no cache, everything will just run more slowly - each time PT3 needs a statistic it will need to calculate it from the original hand histories. Unfortunately at this point the easiest suggestion for you in order to get everything up to date might well be to export and reimport your hands into a new database piecemeal, importing large chunk at first then rebuilding the cache and then smaller pieces after that and using the Update function. Update will attempt to determine which is faster: update or rebuild and use the appropriate method. So if you import small amounts to a completely up to date cache, it should always select and use Update. Unfortunately it is not possible to pause and restart the cache update or rebuild process at this point in time.

I started capturing SQL and realized it was dropping the cache table at the beginning. I figured out how to rebuild in sections (id_player > X and < Y). I can make that work for me for now. I do wish it wouldn't lock me out when doing housekeeping. No reason I cant play live using another DB and capturing only current session stats. Off to make feature suggestions.... Thanks for the reply.

We're definitely looking at incorporating features like that for future releases, but it will be a while before we can get to that point. I'm glad to hear that you've got everything working for you now.
