Hi there,
I'm asking for a friend who's English is even more worse than mine.
Is there any knowledge about the disk space a Mediawiki installation needs? More special:
1. Is every revision saved? Meaning: if I change a slash into a backslash in a text of 12 kB is the space needed changing to 24 KB? And if I change a "then" to a "than" ist it changing to 36 kB than?
2. If I delete an article as an administrator, is it really wiped off the disk?
Thanks in advance, Sebastian
Hiya,
- Is every revision saved? Meaning: if I change a slash into a
backslash in a text of 12 kB is the space needed changing to 24 KB? And if I change a "then" to a "than" ist it changing to 36 kB than?
Yes, every revision is saved. And yes, this means that the database can grow quite big quite quickly, but you can set $wgCompressRevisions to true in your LocalSettings.php to combat this[1]

No. It'll just be marked as deleted, meaning (among other things) it'll not be accessible to non-admins anymore.
Hi!

That must be very bad English! :-)

Yes/no/it's complicated.
Usually yes, you have multiple versions of text stored separately. There is, however, batch compression script, that can either calculate deltas, concatenate, compress and write a blob, or just simply concatenate/compress and write a blob. On articles with large edit histories this can compress to 1% :)

No.
