Hi Gasper,
MySql allows to package the index - to get its size smaller and to gain
performance.
Some information about that can be found here:

Hi, Philip,
RE:

OK, first I naively typed:
explain create table test2 select * from TEST where MMi < 9000;
but of course, this does not work.
The simple select that uses MMi_m as index (and takes up to an hour):
mysql> explain select * from TEST where MMi_m
Questions;
1. Is there a way to decrease random seeks? E.g. mysqld config
parameters, increase some buffer/cache sizes?
2. Optimize table: is there a way to rearrange data so that random
seeks are minimized?
3. If we have to live with large number of random seeks does anyone
know how the underl

Hi,
we have a table with many (~0.5 billion) records and a geometry field
which was defined as a simple "point". The `show table status` shows that
the row format is dynamic, however, a simple point in the GIS
representation has a fixed format (see: WKB: 21 bytes: 1 for MSB/LSB, 4

Hi,
Yes, I don't actually know if I have very large blogs, but the possibility
exists, and is quite large.
I am running FreeBSD so I don't have the ulimit program, the only program I

Hello,
There is a table (TEST) with ~100 million records, 70 columns (mostly
integers, some doubles, and a few short fixed char()), and has a ~100Gb
size.
The table has a single (not unique) index on one integer column: MMi.
If I invoke a simple select based on MMi, then the selection is VERY sl
