Hello all,
Some time back I posted a query to build a site with 150GB of database. In last
couple of weeks, lots of things were tested at my place and there are some
results and again some concerns.
This is a long post. Please be patient and read thr. If we win this, I guess we
have a good

2) Creating index takes huge amount of time.

Hi,
it seems you have to cluster it, I don't think you have another choise.
Hmm.. That didn't occur to me...I guess some real time clustering like usogres
would do. Unless it turns out to be a performance hog..
But this is just insert

Well the test runs were for 10GB of data. Schema is attached. Read in fixed
fonts..Last nullable fields are dummies but may be used in fututre and
varchars
are not acceptable(Not my requirement). Tuple size is around 100 bytes..
The index creation query was
CREATE INDEX index1 ON tablename

The index creation query was
CREATE INDEX index1 ON tablename (esn,min,datetime);

Just an idea, I noticed you use char(10) for esn and min, and use this as
index. Are these really fixed len fields all having 10 bytes?
10 bytes. Those are id numbers.. like phone numbers always have
If you are seeing very slow performance on a drive set, check dmesg to see
if you're getting SCSI bus errors or something similar. If your drives
aren't properly terminated then the performance will suffer a great deal.
