Hi, Pipes
Is it reliable to use MySQL 5.1 in a commercial product now since it is
still a beta version?
Hmmm. Probably depends on what you are doing with it... But, in
general, it's fairly sta ble at this point but, like all beta software,
cannot be considered a production version.
Cheers,
Jay

That said, you can get horrible performance out of mysql with tables
as
small as 100,000 records if you don't structure your queries correctly
or use a good table structure. If I know the tables are going to grow
quickly and I don't need the entire dataset all the time, I'll use
merge
tables. This makes it easy to remove "old" data easily from the
default
table set.
Hi! Have you tried out the new partitioning features of MySQL 5.1 to do
this? Would be cool if you had some performance numbers comparing the
older MERGE table method with the newer partitioning...
Cheers!

Hi,all
The number of the records in one table increase constantly. As
evaluated, the amount would increase to at least 30 millions within
one
year. So we worry about whether mysql could handle such a big amount
of
records with good performance. Or need we some other solutions to
avoid
this problem ,such as using Partition, dividing a big table and etc.
Any
help or idea would be greatly appreciated.
Best Regards
