A friend of mine asked me yesterday for help for his bachelor thesis.

He wants to write about MySQL internals in regards to BLOB storage / usage.

We had a veeeerrrry long discussion....

And found a loooot of scary internet pages.

It's so .... Insane....

What some people with doctor titles or higher education generate...

Isn't content. More poo...

Most "blogs" / "articles" or whatever the author named it were missing all kinds of relevant data (version, configuration, anything relevant) but full of opinionated / biased bullshit.

Highlights were:
- we store lot of BLOB data, Backups take long and require more space
(you store additional data in an database, whaddya expect???!!!!)

- interesting guesswork about locking without any reference (interesting since it was sometimes so far away from reality that it looked more like quantum physics)

- storing blobs means that _each_ blob entry will be stored in a separate file (without any reference, but if an RDBMs did that... It would end in an amazing fireball I guess)

- BLOB's bad since it can represent only the file content, the database cannot distinguish wether it's an MP3 / MPG or anything like that...

(Ehm. Yeah. And an database cannot distinguish if you store under "Name" an Name or gibberish?!)

I somehow think that some people made an doctor and post this gibberish nonsense so people stay dumb to give them a job...

Like the TV repair men who steals the batteries from the remote.

Even conspiracy theories were more convincing
