Some of you may have followed the thread about my mailing archive system
that uses PostgreSQL.
The database is growing quickly and I want to make sure the performance is
going to be OK, so here's a question:
I have a table with records like this:
fld_mail_list (int) | etc | etc | fld_mail_body
1 x x x <----big TEXT Field ----->
2 x x x <----big TEXT Field ----->
1 x x x <----big TEXT Field ----->
4 x x x <----big TEXT Field ----->
1 x x x <----big TEXT Field ----->
1 x x x <----big TEXT Field ----->
7 x x x <----big TEXT Field ----->
1 x x x <----big TEXT Field ----->
1 x x x <----big TEXT Field ----->
7 x x x <----big TEXT Field ----->
1 x x x <----big TEXT Field ----->
8 x x x <----big TEXT Field ----->
Essentially, I have a several different mailings lists being archived into 1
big table, and the key to accessing them is using the fld_mail_list key.
Am I going to run into huge performance problems on this? Should each
mailing list be archived in its own table??
When I do a
SELECT * FROM tbl_mail_archive WHERE fld_mail_list=1 AND
fld_mail_body~~'%keyword%';
am I going to get killed with a performance hit?? It's running OK now, with
the table at 20MB, but I have 100MB more worth of letters to drop into the
table..... 8-)
