This patch cleans up two tests which were a bit fragile from other failing tests. It also removes some variables associated with removed RAID support.

RAID support for MySQL. Raid 0 (stiping) only implemented yet.
|
|
||||||
|
|
||||||
Why RAID? Why it must be in MySQL?
|
|
||||||
|
|
||||||
This is because then you can:
|
|
||||||
1. Have bigger tables than your OS limit. In time of writing this
|
|
||||||
we are hitting to 2GB limit under linux/ext2
|
|
||||||
2. You can get more speed from IO bottleneck by putting
|
|
||||||
Raid dirs on different physical disks.
|
|
||||||
3. Getting more fault tolerance (not implemented yet)
|
|
||||||
|
|
||||||
Why not to use RAID:
|
|
||||||
|
|
||||||
1. You are losing some processor power to calculate things,
|
|
||||||
do more syscalls and interrupts.
|
|
||||||
|
|
||||||
Functionality is supplied by two classes: RaidFd and RaidName.
|
|
||||||
RaidFd supports funtionality over file descriptors like
|
|
||||||
open/create/write/seek/close. RaidName supports functionality
|
|
||||||
like rename/delete where we have no relations to filedescriptors.
|
|
||||||
RaidName can be prorably unchanged for different Raid levels. RaidFd
|
|
||||||
have to be virtual I think ;).
|
|
||||||
You can speed up some calls in MySQL code by skipping RAID code.
|
|
||||||
For example LOAD DATA INFILE never needs to read RAID-ed files.
|
|
||||||
This can be done adding proper "#undef my_read" or similar undef-s
|
|
||||||
in your code. Check out the raid.h!
|
|
||||||
|
|
||||||
Some explanation about _seek_vector[]
|
|
||||||
This is seek cache. RAID seeks too much and we cacheing this. We
|
|
||||||
fool it and just storing new position in file to _seek_vector.
|
|
||||||
When there is no seeks to do, we are putting RAID_SEEK_DONE into it.
|
|
||||||
Any other value requires seeking to that position.
|
|
||||||
|
|
||||||
TODO:
|
|
||||||
|
|
||||||
|
|
||||||
- Implement other fancy things like RAID 1 (mirroring) and RAID 5.
|
|
||||||
Should not to be very complex.
|
|
||||||
|
|
||||||
- Optimize big blob writes by resorting write buffers and writing
|
|
||||||
big chunks at once instead of doing many syscalls. - after thinking I
|
|
||||||
found this is useless. This is because same thing one can do with just
|
|
||||||
increasing RAID_CHUNKSIZE. Monty, what do you think? tonu.
|
|
||||||
|
|
||||||
- If needed, then implement missing syscalls. One known to miss is stat();
|
|
||||||
|
|
||||||
- Make and use a thread safe dynamic_array buffer. The used one
|
|
||||||
will not work if needs to be extended at the same time someone is
|
|
||||||
accessing it.
