There is no primary key on that table since the same employee will access more than 100 sites per day. If there is 100 employees then the rows inserted per day will be ~ 100*100= 1. If it grows till 2 months or 3 months then the table size will become larger. As we all know the default table size in MySQl is 4 GB. Default table size maybe but a MyISAM table can grow beyond 4GB without problems. (just try it by inserting lines with a script) The general advice for handling such big tables is to either build a map table that maps long hostnames to numbers (4 = www.google.com) to safe space or to use one table per day and use a Merge-Table to access them all in one SELECT. bye, -christian- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: URGENT: Question on table storage
Hi, I have the following table in mysql 5.0.20... employ == empid date_time site I am using this table to store all the websites accessed by each employees. There is no primary key on that table since the same employee will access more than 100 sites per day. If there is 100 employees then the rows inserted per day will be ~ 100*100= 1. If it grows till 2 months or 3 months then the table size will become larger. As we all know the default table size in MySQl is 4 GB. Can anyone explain will it produce issues in the future? How to overcome this? How to design a table for this scenario? maybe this is still correct: http://jeremy.zawodny.com/blog/archives/000796.html But perhaps you don't need it at all: 1 records * e.g. 300 byte = 300 byte/day 4GB = 4294967296 byte 4294967296 byte / 300 byte/day = 1431 days No issues for about 3 years. And after that time you could simply create a new table. hth, Tom Horstmann -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
