We are currently on RDS for hosted MySQL but are considering moving to one of the fault tolerant MySQL addons for heroku. The two main ones seem to be xeround and ClearDB, but I'm having a hard time determining the differences between them. We're mainly interested in fault tolerance, consistent and fast performance and UTF8 charset support. Any experiences with either welcome. There doesn't seem to be much discussion of either out there.
I struggled with Xeround. We had an app built for none heroku environment that we migrated to Heroku. We tried Xeround but there was some problems with some of our queries for some reason when run against Xeround. Drastic but we ended running a Slicehost mySQL instance. We've recently re-reviewed and found ClearDB to work much better for us so we're now running on that Db.
I have to say that I totally agree with Jhon. I had the same issues.
I was running my app [play + heroku + xeround ] but some queries where giving me no results, so I switched to clearDB and everything went fine.

I'm writing this after about 3 days of researches without ending in a solution that has sense.
I had several setups to host Wordpress sites, using Apache directly and using Plesk, everything hosted on AWS. Recently I setup a new Plesk installation on a m5a.xlarge instance, and things started behaving strange.
Basically the performances on this new instances, profiling the TTFB of the wp-login.php are unacceptable. We are talking about 2.0 secs in comparison of the old setup.
To make the thing short, I made tons of tests and the results are the following:
TTFB 0.3-0.4 on Apache AWS Linux 2 with Mariadb 10.2, t3.medium
TTGB 0.3-0.4 on Plesk t3.medium running Mariadb 5.5
TTGB 1.8-2.2 on Plesk m5a.xlarge running Mariabdb 10.5 (the last one).
Final test, bring up a new machine m5a.xlarge and installed another plesk, TTFB 0.2-0.5 but plesk installed Mariadb 5.5
Now first of all I did not understand why plesk intalled 5.5 twice and 10.4 on one instance. There's no choice during the installation.
I made every kind of test, I have the sensation that there's something about encoding and collations, but also running a mysql benchmark from withing WP, no differences are shown and the results are pretty much the same.
So anyone can show the light what's going one there ? Mariadb 10.5 ? Or is it possibile a faulty disk ? Ever happened ? (I also detached the disk and tried on another instance, no difference, so faulty instance is out of scope).
Thanks !
To anyone that may experience a foolish problem like mine, basically when I did the installation of the faulty server, I updated MariaDB to 10.5. The problem was there, it does not play nice with Wordpress, that's all. I found a lot of people reporting performances regression with Wordpress and even this sounds weird, that's the problem. I've rebuilt a server, kept MariaDB 5.X and everything is going smooth.
BTW Plesk support has been totally useless keeping uninstalling my plugins and telling me that the problem was in the plugins.. :/
I just learned about how docker-sync can help speed up local development work when on MacOS or Windows. It's much faster. However, I wondered if it also makes sense to use docker-sync for the database files?
I noticed that MySQL is still running quite slow when doing consuming tasks.
I work with a software developed in Visual Basic 6 which MySQL is the database. Our application works in a local network and always worked fine, but just one costumer is having an issue. The question is when the consultant does something in our application the MySQL database takes too much time to search or stops to work, but when I'm on the machine that is installed MySQL (5.5) it is working.
I already have tried some tips, changing my.ini file lines, grant all command, reinstallation and etc.
Maybe the problem could be the local network? Any advice?
I have to apologize for my english if something don't look right,
Regards.
Well, I solved my problem, It was easier than I thought.
I had to go in Performance Options from Windows and change the Virtual Memory, just this.
I am using sphinx to index my content. I used it in my development environment (xampp) and it worked fine. Now I took it to the server (same config file), and it is giving me trouble.
I have a VPS Windows 2008 server with Plesk panel. I am the administrator. the problem is that when i run the indexer tool, it tells me that it found 0 docs and indexing 0 docs. So it seems like it is working fine as far as accessing the database, but it just doesn't find any docs. Does anyone have any ideas, I spent a whole day playing with the configuration and database with no success.
Thanks.
Well maybe the database table that sphinx is trying to index is empty?
Either way would suggest adding debug command line switches when you run indexer. Eg --verbose, --print-queries etc. They will probably give you a better clue where the problem lies.
Really new with the whole phpMyAdmin thing.
I was wondering, when I enable my computer for web sharing, then install phpMyAdmin, is this detrimental to my computer in anyway (mainly in speed)? If so, I would opt for just using another (older) computer. But that would be a hassle.
Thank you in advance.
There are potential security issues depending on your set up and a slight impact on speed since youll be running the webserver and mysql in the background but its nothing huge in terms of performance.
With that said theres no need to use phpmyadmin locally. Its kind of pointless since you can use a real mysql client like Sequel Pro, Navicat, or MySQL Workbench. I prefer Sequel Pro myself since its free and pretty lightweight.
