MySQL to Adopt Solid Storage Engine
hmart writes "As seen on ZDNet's Open Source Blog MySQL is taking another step to defend from Oracle's recent acquisitions of InnoBase and Sleepycat. From the article: 'MySQL responds by getting Solid Information Technology, a proprietary database vendor, to take its solidDB Storage Engine for MySQL open source, under the GPL, starting in June.'"
It seems that Oracle is not taking the threat from MySQL lightly. The purchases they have made have been quite public, but they also have been quietly hiring developers from many different open source projects. It is scary how many of them have dropped off the radar. On a side note: I was always under the impression that MySQL was a 'amateur' database. I was very surprised when I was forced to switch from Microsoft SQL 2000 - MySQL had a much smaller memory footprint, and the performance just blew me away. To this day I still cannot believe the performance difference. It really speaks to the power of Open Source.
buy out Solid Information Technology.

No matter which storage engine you use in MySQL, the SQL syntax is still the same. All you have to change is the ENGINE= line in your schema definitions.
Within two clicks of the Slashdot story page, I found THIS.
If you want news from today, you have to come back tomorrow.
MySQL is about choice... You can choose to use it or you can choose to use something else. You can choose to store your data in InnoDB, BerkeleyDB, Cluster, MyISAM, Memory, CSV
"Choices" is positive spin. Some might say that MySQL is all about sacrifices. Here are some examples:
(1) "MySQL has many applications written for it"
* Not if you enable strict mode, or if you use storage engines that don't support the features you need.
(2) "MySQL is optionally SQL compliant with strict mode"
* Only if you want to forego 99% of the existing MySQL applications, and start fresh.
(3) "MySQL has transactions"
* Not in MyISAM, which means no full text indexing.
(4) "MySQL is free"
* Only if your application which links against the client library is also GPL.
(5) "MySQL is fast"
* Only if you use MyISAM, which means no transactions or many other features that aren't available in MyISAM.
I could go on. Anyone can talk about how MySQL has a feature, but you have to make sacrifices for those features. And I think many of those are bad, unnecessary sacrifices. MySQL implements features not to give their users choice, but to give MySQL AB a marketing advantage. Their advocates and salespeople will always say "yes" to all of those features above, but it's not until later that the customer realizes that they can't use the features together.
Social scientists are inspired by theories; scientists are humbled by facts.
If your application is designed for MySQL specificially without strict mode, then strict mode is not for you. It is more useful to people porting their applications from some other product to MySQL than to the existing MySQL user base.
Ditto above. Perhaps the existing MySQL user wants to go to strict mode in order to support databases *other* than MySQL. Have you concidered that?
MyISAM was never designed with transactions in mind. It performs its intended function excellently. Not all data is useful to keep in some kind of transaction context - take for example a table mapping UPC codes to product names and descriptions: it will never need to change in a transaction so having transactional overhead would be wasteful.
Myth used to scare people away from opensource GPL code.
Some people would disagree with that statement. Quite a lot of people have found that for their needs, MySQL is lighter and faster (or at least, as fast as the big name products) even when never using MyISAM tables.
There will be people whose needs are best served with products from Oracle, IBM, Microsoft, Sybase... I am sure that no one in MySQL claims that it is the only solution to all problems: MySQL is a young database product which is actively being developed so it will improve.
No sig. Move along - nothing to see here.
I'm just worried about this quote from Solid's V.P. of Marketing: It sounds like MySQL will use only a subset of the Solid product. So how good this news is will depend on how complete a subset of its product Solid opens.
I have been using Perl for 5 years. After 1 month with Ruby, I'm not going back.
That's like saying "i have been eating dogshit for 5 years. After 1 month with steak & eggs, i'm not going back.". Hardly an impressive statement at all.
There will be no need to pressure existing users off from InnoDB .... InnoDB is GPL code and as such will always be available: This is the strength of open source software, it is very hard for players to pick up their toys and leave the sandbox. If they leave the sandbox, they have to leave their toys there. Besides, Oracle has stated that they do not intend to change Innobase's business. Lets hope that they keep that promise.
Of course, MySQL can encourage people to use a particular product choice based upon future roadmaps but I don't imagine that InnoDB support will ever be axed.

This is typical LAMP programmer thinking. What do I need transactions and data integrity in a database for? I'll just code the checks into my application. I prefer instead to put checks both in the database and in the application.
This is no myth. MySQL's client libraries are definitely GPL. If you link to them you must abide by the terms of the GPL. Alternatively, you can purchase a license from MySQL AB. MySQL AB spins this up so much saying that they are open source but what they really mean is that they are open so long as you are open.
I'll stick with PostgreSQL. Unlike MySQL, PostgreSQL is a serious alternative to Oracle or MS SQL. It is also BSD licensed and thus there are zero restrictions on its usage within a commercial product and there is no need to purchase a commercial license.
MySQL is okay for the LAMP mentality but when you start getting in to ORM/ERM (Object/Entity relational mapping) with packages like Rails's Active Record or WebObjects's Enterprise Objects you need a more serious database. As another poster has pointed out in this thread I give it only a few more years before mainstream open source web development moves into the ORM camp.
... while others (PostgreSQL) have all one needs. I guess that's an unavoidable dynamic of free software (and a good one as well -- just like in other competing open source projects). So probably one day MySQL will have everything that PostgreSQL has today, but why wait ? It's mostly transparent to move from one to the other, and there are tons of guides and scripts to convert from MySQL to PgSQL. Even PhpMyAdmin has its Pg pendent (PhpPgAdmin).
And it's painful to go back when you've learned to do proper logic separation using stored procedures, triggers, views and transactions, things that way too many projects duplicate in the PHP or Ruby front-end, relegating the DB to the "simple" role of being a storage backend (even Ruby on Rails forces you to think that way via the MVC architecture).
For that purpose, use SQLite -- it does what you need, is very high performance (on-disk, non-concurrent access -- can't get any faster than that). For real solid DB work, with garanteed integrity, just the way RDBMS were meant to be, go for PgSQL.
