MySQL 5.6 vs. MariaDB 10.0
+6 Vote Up -8Vote Down

A high-level comparative overview of the features

With the recent GA release of MySQL 5.6, there have been a lot of questions about where MariaDB stands with regards to MySQL 5.6.  SkySQL will of course support both as Patrik explained in his recent blog post, but there are many questions about the technical differences. Rasmus from Monty Program gave a detailed view on MariaDB 10.0 here but I thought it would be beneficial to share a comparison table of the two. MariaDB recently released a benchmark including various versions of both MariaDB and MySQL (as did DmitriK from Oracle), but this post will focus solely on

Comparison Between Solr And Sphinx Search Servers (Solr Vs Sphinx – Fight!)
+2 Vote Up -0Vote Down

In the past few weeks I've been implementing advanced search at Plaxo, working quite closely with Solr enterprise search server. Today, I saw this relatively detailed comparison between Solr and its main competitor Sphinx (full credit goes to StackOverflow user mausch who had been using Solr for the past 2 years). For those still confused, Solr and Sphinx are similar to MySQL FULLTEXT search, or for those even more confused, think Google (yeah, this is a bit of a stretch, I know).

Similarities

  • Both Solr and Sphinx satisfy all of your requirements. They're fast and designed to index and search large bodies of data efficiently.
  • Both

Document oriented data stores
+1 Vote Up -0Vote Down
A document oriented database or data store does not use tables for storing data. It stores each record as a document with certain characteristics. So a multiple documents in this type of store can have different characteristics - which means different number of fields per record and different fields per row. The benefit would be that if you are using a document oriented database for storing a
OSCON 2008 Popularity Contest

I didn't get a chance to go to OSCON 2008. Bummer. But I can live vicariously through google. So, along with all of the announcements you've heard from OSCON, I know present the OSCON 2008 - Google popularity contest. This is a completely unscientific survey of google hits. I was searching blogs and news. I started with just news but the blogs hits really upped the numbers.

To run these searches, I use "oscon 2008" and the search term, for example:

"oscon 2008" mysql

In the case of open source, I also quoted "open source".

I'm using google's about number. I didn't sit and count each hit. ;-)

Is Drizzle good for MySQL?
+0 Vote Up -0Vote Down

Have you heard of Drizzle? It was announced at OSCON yesterday and is all over the blogosphere. From the Drizzle FAQ:

* So what are the differences between is and MySQL?

No modes, views, triggers, prepared statements, stored procedures, query cache, data conversion inserts, ACL. Fewer data types. Less engines, less code. Assume the primary engine is transactional.

Also from the FAQ is that, right now at least, there is no intention to make this run natively on windows and they make the point:

* "This is not a SQL compliant relational..."

Very true, and we do not aim to be that.

It is a fork of MySQL that takes it backward to pre-5.0 in features

MySQL vs Postgres, Again - Is Postgres Better?
+0 Vote Up -0Vote Down

I was browsing the web on this lazy Sunday afternoon and ran across a good article on the Rarest Words blog. The author was trying to get Django installed and running with Postgres. From the author's own admissions, he is not a Postgres fanatic.

Well, this and last year I hear everywhere that PostgreSQL is the way to go and that usage of mySQL in 2008 makes people puke… But without any real arguments (besides "Postgres is the way to go").

After some not so compatible errors with these not so compatible databases, the author did get it working and ran some benchmarks. Postgres did not turn out faster than MySQL. If you ask anyone in the Postgres community

Take an Open Source Database Survey

LewisC's An Expert's Guide To Oracle Technology

Do you know which open source feature is the most important? Do you know which open source database rocks and which one sucks? Is MySQL better than Postgres? Is Ingres worth considering? How does Firebird compare? Have you used, or have you considered using, an open source database?

Take a survey. It's only 15 questions so it takes just a few minutes.

I'll post a link where you can get the results once they have been compiled and prepared.

BTW, this isn't my survey. I'm just passing on the link.

A Better diff Or What To Do When GNU diff Runs Out Of Memory ("diff: memory exhausted")
+0 Vote Up -0Vote Down

Recently I ran into major problems using GNU diff. It would crash with "diff: memory exhausted" after only a few minutes trying to process the differences between a couple 4.5GB files. Even a beefy box with 9GB of RAM would run out of it in minutes.

There is a different solution, however, that is not dependent on file sizes. Enter rdiff – rsync's backbone. You can read about it here: http://en.wikipedia.org/wiki/Rsync (search for rdiff).

The upsides of rdiff are:

  • with the same 4.5GB files, rdiff only ate about 66MB of RAM and scaled very well. It never crashed to date.
  • it is also MUCH faster than diff.
  • rdiff itself combines both diff and patch capabilities, so you can create deltas and apply them using the same

MySQL vs Postgres Wiki
+0 Vote Up -0Vote Down
There is a new wiki comparing MySQL to PostgreSQL. Because it's a wiki, hopefully it can be kept updated so that it's current AND accurate. The wiki is MySQL vs PostgreSQL. Personally, I'd like to see this grow into a universal comparison site that the community could keep updated. LewisC
