Hello Josh,
why you moved your table to InnoDB? Your description doesn't sound like the
tables rows
are accessed concurrently and need to be locked? Are you sure you need
InnoDB for this table?
If you need InnoDB you probably need to redesign your queries and table
structure to get them
more
The rows in this table are accessed concurrently as any activity on the
site is recorded/added/updated to this table. We have several others
which serve similar purposes, (sessions, totaltraffic, etc...).
Is the performance lag occurring with read-only queries and updates/inserts
to the
between 16-32MB if you have many transactions.

Right... and perhaps try MySQL Enterprise Monitor. A trial is available from

Dear Marco,
i'm not sure, this can be solved by MySQL itself, but if you're e.g.
using php you may try to use mysql_pconnect () instead of
mysql_connect (). Please see

Hi Craig,
I have a very large web app that uses timestamp for unique IDs.
Everything was rolling fine until we started getting many users per
second, causing some of the unique IDs to not be unique -- users were
being assigned the same timestamp. Since the web app is so large we

Hi all,
i want to store an unfixed number of object-characteristics

If i use one table for all characteristics i need as many
columns as there are datatypes used.
Thanks Chris,
Will you have an object hierarchy of any type to speak of?
no hierarchy, they're all roots.
Which language are you looking at building this funky thing
in? If it's
Java or C++, you might want to look at persistant object

The question is how can I use some sort of statement using
mysql and php
to select all rows between 1 and 0 NOT 0 and 9 like the
above statement
performs.
Sure, an option was nicer, but isn't the following possible?
SELECT ... WHERE ... AND ( x BETWEEN 1 AND 9 OR x BETWEEN 0 AND 1 )
Lee,
I get the feeling there is a more efficient method using
binary operations

i think you should try to avoid such thing as much as you can.
