Oh I love these things: http://techcrunch.com/2012/08/22/how-big-is-facebooks-data-2-5-billion-pieces-of-content-and-500-terabytes-ingested-every-day/

Every day there are 2.5B content items shares, and 2.7B "Like"s. I care less about GiGo content itself, but metadata, connections, relations are kept transactionally in a relational database. The above 2 use-cases generate 5.2B transactions on the database, and since there are only 86400 seconds a day, we get over 60000 write transactions per second on the database, from these 2 use-cases alone, not to mention all other use-cases, such as new profiles, emails, queries...

And what's the size of new data, on top of all the existing …

On the 8/16 I conducted a webinar titled: "Scale Up vs. Scale Out" (http://www.slideshare.net/ScaleBase/scalebase-webinar-816-scaleup-vs-scaleout):


ScaleBase Webinar 8.16: ScaleUp vs. ScaleOut from ScaleBase
The webinar was successful, we had many attendees and great participation in questions and answers throughout the session and in the end. Only after the webinar it only occurred to me that one specific graphic was missing from the webinar deck. It was occurred to me after answering several audience questions about "the difference between …

I got a few questions like the ones below that I’d like to address to avoid further confusion.
How exactly secure is ClouSE for MySQL, the first secure database in the cloud? Am I protected against standard application level security attacks or even accidental admin mistakes?
With the help of ClouSE I get instantaneous backup for my database on the highly durable cloud storage. But how would I protect my data in case a malicious attack or an accident did occur?

Re: security

I’ve got a comment pointing out that data encryption on the storage level doesn’t protect from SQL injections.  Of course, data encryption does not protect from SQL injections (as long as there is SQL involved, there will be a risk of a SQL injection).  Neither does it protect from the infinite number …

MySQL is a database of compromise. Compromise between running a production-ready relational database and being popular with all sorts of hackers - mostly the ones that don't really like SQL. And because they don't really like SQL, they choose MySQL, as MySQL is very forgiving. It is just as forgiving as their favourite language PHP, … Continue reading MySQL Bad Idea #384 →

With its distributed, shared-nothing, real-time design, MySQL Cluster has attracted a lot of attention from developers who need to scale both read and write traffic with ultra-low latency and fault-tolerance, using commodity hardware. With many proven deployments in web, gaming, telecoms and mobile use-cases, MySQL Cluster is certainly able to meet these sorts of requirements.

But, as a distributed database, developers do need to think a little differently about data access patterns along with schema and query optimisations in order to get the best possible performance.

Sharing best practices developed by working with MySQL Cluster's largest users, we recently ran a Performance …

This past week I attended OSCon, the annual conference for open source’s true believers. And there was a religious fervor in the air, particularly from the point of view of someone more accustomed to Oracle conferences.

And if open source is the religion, proprietary closed-source companies are the devil. That having been said, I was surprised how virtually all large companies were demonized. Even long-time defenders of open source like IBM were ignored at best. That didn’t prevent them from coming though, with Microsoft and HP in particular with high-profile sponsorships and PR offensives that didn’t seem to have much influence with the crowd.

The companies generating buzz were the small companies built around development of their own open source products. There are a surprising number of them out there, especially relating to multiple forks of a popular product like MySQL or …

Meet The SkySQL Team At OSCON 2012!

“I remember my first OSCON in 2001 and the passionate debates we had on the impact the open source movement was going to make …”

This is a quote from a conversation that some SkySQLers were having this week in Paris, where we met to discuss the future - ours and that of the MariaDB & MySQL databases as well as open source technologies in general!

Earlier this week we all read GigaOM's article with this title:
"Why the days are numbered for Hadoop as we know it"I know GigaOM like to provoke scandals sometimes, we all remember some other unforgettable piece, but there is something behind it...

Hadoop today (after SOA not so long ago) is one of the worst case of an abused buzzword ever known to men. It's everything, everywhere, can cure illnesses and do "big-data" at the same time! Wow! Actually Hadoop is a software framework that supports data-intensive distributed applications, derived from Google's MapReduce and Google File System (GFS) papers.

My take from the article is this: Hadoop is a foundation, low-level platform. I used the word …

Can OLTP database workloads use Amazon S3 as primary storage? Now they can, thanks to the Cloud Storage Engine (ClouSE), but the question is: how fast?

• ClouSE on “across the street” vs. “across the continent” cloud storage
• ClouSE vs InnoDB
• ClouSE benefits

To answer the question about performance, we decided to run db_STRESS benchmark on a MySQL database in Amazon EC2.  We compared 3 configurations:

• “Across the street storage”: ClouSE with data stored in S3 in the same …
