Too many connections? No problem!
+8 Vote Up -0Vote Down

Did that ever happen to you in production?

PLAIN TEXT CODE:

  1. [percona@sandbox msb_5_0_87]$ ./use
  2. ERROR 1040 (00000): Too many connections

Just happened to one of our customers. Want to know what we did?

For demo purposes I'll use sandbox here (so the ./use is actually executing mysql cli). Oh and mind it is not a general-purpose best-practice, but rather a break-and-enter hack when the server is flooded. So, when this happens in production, the problem is - how do you quickly regain access to mysql server to see what are all …

Piper Jaffray on the Cloud
+0 Vote Up -1Vote Down

Piper Jaffray has published a 300+ page study on the cloud computing industry based on a recent survey undertaken of 100 CIOs. Bottom line, cloud computing is expected to grow significantly over the next five years. 

    Survey respondents expect the mix of cloud computing to escalate strongly to 13.5% in five years. This equates to a five-year CAGR of 19.2%, or 23.9% when we also incorporate IDC’s forecast that total software budgets will grow 4.7% annually. In other words, software spending will grow gradually in the next five years, but the mix of spend allocated to cloud-based applications will likely surge rapidly. …

Fast Backups of MySQL Running on Amazon EC2
+2 Vote Up -1Vote Down

If you are running your MySQL databases on the Amazon EC2 compute cloud, Zmanda Recovery Manager (ZRM) for MySQL can perform fast full backups of these databases by using Elastic Block Store (EBS) Snapshots. ZRM takes only a momentary read lock on the MySQL database during the creation of the snapshot, in order to ensure consistency of the backed up database archive. MySQL Backups using Amazon EBS snapshots are differential backups, meaning that only the blocks that have changed since your last full backup (via EBS snapshot) will be saved. For example, if you have a database with 100 GBs of data, but only 5 GBs of data …

Looking at Redis
+1 Vote Up -0Vote Down

Recently I had a chance to take a look at Redis project, which is semi-persistent in memory database with idea somethat similar to memcache but richer feature set.

Redis has simple single process event driven design, which means it does not have to deal with any locks which is performance killer for a lot of applications. This however limits it scalability to single core. Still with 100K+ operations a second this single core performance will be good enough for many applications. Also nothing stops you from running many Redis instance on single server to get advantage of multiple cores.

As of today Inuits is rebranding to Pinuits,

We've had good feedback on the new name so far. Different people told me the name matched better to what we are doing . Actually my wife thinks our new name is much better as at least the Pin in Pinuits refers to our favourite Tux again ..

First Olio Release
Employee +0 Vote Up -0Vote Down

We have just released the first binary version of Apache Olio for both the PHP and Rails implementation. Both implementations have been tested quite thoroughly now and we think they are robust enough for serious use - especially for performance testing the workloads.


I introduced Olio in a previous post. It is a toolkit that includes a sample web2.0 application implemented in both PHP and Rails that includes a load generator to drive load against the application.
