| Thank goodness for some news. I was about to punch the slave DB in the face! |
Meri said: I've been getting that error lately today as well.Couldn't open slave database. Please try again in a bit. it started again :< |
 |
| The Slave Database is seriously bugging me, [The fact that I have to refresh 3 -7 times] Hope you get it fixed, cause I dont want another simple Bug/Error/Site Lag. |
| thanks for everything Xinil |
 |
| Yeah, kinda old indeed, but a little word to know things are getting worked on is always very much appreciated. Surely much better than having lots and lots of glitches and not even knowing is somebody's giving a damn about it or what. So thanks, personally I decided to not lose hope for now and continue to patiently wait for things to get fixed. |

| I thought it was just my computer... or my account... or I was going to have to go insane... now I know I'm not Thank you so much... ^^ |

| Everything's working alot better on my end...is everyone on the page? |
| Good Luck Xinil. |
| I don't really mind waiting, as long as the lists don't get deleted or something :O After all, this is a free service :D so thank you for trying to keep this running in good condition :) P.S. Funny, I got an error while trying to open this thread xD |
         |
| Haven't been on in several days, stupid math homework being a pain in my rear, but thanks for the heads up. |
 |
| Thanks god. I think it was only my problem. Well, good luck~ |
BradIey said: Why's it called "slave" database? o_o My guess is that it is a subordinate database server which handles a certain set of the site's database. Might be the database server that holds all the anime entries, or just manga entries...or whatever. |
| Thanks for telling us something is wrong :) It was strange that it didn't update automatically. |
     |
| Ok then good to know it's being worked on, goodluck !! :) |
| Can't take it anymore ; w ; I think I will snap soon. |

Thanks for the update, though. <3 At least the lag isn't just aboslutely tearing the whole site down, and Xinil is actually trying to fix things. :I Unlike FictionPress. FP mods, if you're out there, and reading this...FUCK YOU. WE'VE DEALT WITH THE GODDAMN LAG FOR TWO YEARS AND YOU DON'T EVEN CARE ;_____; |

The problem is of synchronizing database changes across multiple servers seamlessly, but in a way that does not incur massive amounts of strain on the servers involved. You're talking about an environment where there are thousands, if not tens of thousands of people browsing every minute; if there is any snip of inefficient code, it will have an exponential effect because of how many people access a site at once. Yes, it is that fucking complex. I suggest you do a little research before you make flippant and ignorant remarks. ;) It actually is. Or it's a case where someone has no idea what they're doing. Otherwise any other remotely large website (and websites of a much larger magnitude than this one) would have the same error, no? ^_^; More or less, it's probably that the site needs to be rewritten from the ground up with load distribution in mind. Most likely, the codebase would have been initially developed for use with a single server, and just had the multi-server support hacked in along the way. That's just my guess though. |

BradIey said: In technological jargon a master device controlls one or more slave devices unilaterally (meaning the master device can access and mess with the slave device but the slave can't do the same to the master). The current string of errors basically all seem to be that the site can't seem to properly link up to the database for some reason.Obsidian_ said: BradIey said: Why's it called "slave" database? o_o My guess is that it is a subordinate database server which handles a certain set of the site's database.

That's mostly true, though I've done a heavy amount of re-coding over the past year or so, and I'd say roughly 40% of the site is 'new' code with load distribution in mind. |

That's mostly true, though I've done a heavy amount of re-coding over the past year or so, and I'd say roughly 40% of the site is 'new' code with load distribution in mind. I figured as such. And, knowing how hard it is to work on getting a large codebase coherent and unified, it'd be a mess to scrap it all and start fresh. Have you considered having someone else (i.e. another upper-echelon staff member) maintain the older codebase for MAL, and then moving on to do a total rewrite yourself? It might be worth it seeing as how there's so many issues with it on a constant basis, and that there's many sections of the site (e.g. affiliates, donations) that just aren't needed. Not to mention, if you're using a distributed version control system, you can just branch out the newer codebase, and merge in any relevant bugfixes made to the old one as well. I myself am a fan of git, but I'm sure something like mercurial or even bazaar would work just as well for a codebase as large as MAL is likely to have. tl;dr : Web developer sp33k. Run far, far away. edit: Added links to stuff, for those curious as to what in the hell I'm talking about. |

Obsidian_ said: tl;dr : Web developer sp33k. Run far, far away. My head asplode. Also, this was really funny. I've been using MAL for years now, never had this problem ironically til I finally registered the other day o.o I didn't break it, did I? |

| Are you still the only person working on all this? If so, why don't you bring in a couple trusted developers for support? |

| Oh, so that explains the lag. Thanks for informing us! Also, this situation is quite understandable. Hope this gets settled soon. |
 |
| More developers isn't going to fix our database issues. I am not the only database developer. Crave has an entire team of DBA's at their disposal. They obviously have a slew of other sites to run too though, so MAL 'fixing' is slow. TLDR: The underlining issue is not fixable by additional MAL developers. |
| lol oh wow it took me 10mins to load this last page of comments -___- I woner if it's the site or me?..Cause youtube and this site has been slow on loading for me. Edit:It was me.. Offtopic but Verizon sucks -__- |

| Ever since the lag incident the stats on my profil and panel are stuck on the old number of anime. --Problem could also be on the manga page but i don't have any manga in the list, so i do not know for sure--. Are there other people here who also have this problem ? |

ZEFIs_husbando said: Xinil, MAL is obviously punishing you because you quit watching anime agree 100% my thoughts exactly mate |
| I was thinking something in the lines of more caching, maybe using a solution such as Varnish, and then figuring out how to asynchronously commit data to the databases which lies within the cache. But yes this whole thing is very complicated, and programming with load balancing in mind is the only way to go. Maybe even make it more distributable, having parts of the website running on more than just one server. Which I know is already implemented for some parts, but maybe distribute it even more? Anyways, good luck with getting it running stable again! |
| I kinda miss "Whats being watched" list... |
| I shall know no fear as I am fear incarnated |
