Re: MySQL bottleneck
Hi Wiley, I am still not sure if we are talking about 360k threats or clients, but I take your word from the first e-mail. basically I think its possible to setup a big DB (as Google, Yahoo etc. have shown already). About the hardware may I recommend 64 bit Opteron systems and scsi drives (array). Performancewise you have many options to stretch MySQLs legs. - Merge table format (for non transactions) - Raid options included in MySQL - Replication - Cluster Filesystem from MySQL - A "REAL" Cluster One thing that surprise me is that you obviously dont use transactions. Note that your data may corrupt not repairable if you dont take any precautions. Anyway, may I suggest 2 books to get you started quickly. "MySQL Certification study guide" from Paul DuBois "High Performance MySQL" from Zawodny You will probably need more info or books later, but that should get you up to speed within a few weeks. I trust that you have 2-10 boxes near you to get started and see how well that system scales. About posting: Just make Sure you create a new Subject line when starting a new threat or topic. That should do the trick and nobody gets confused. I hope that you find this information useful.

Re: Relative Numeric Values
David, I agree with Kim. Trying to encode information into primary keys is a bit like trying to write a legal contract in chalk on a sidewalk. The contract is washed away next time it rains, the neat looking key order is washed away by errors, species discoveries & reclassifications. The PK doesn't need to mean anything, indeed it shouldn't be made vulnerable to real-world errors of any kind; it's job is strictly logical, as a marker that guarantees row uniqueness and can relate rows in one table to rows in another.. HTH. PB - David Blomstrom wrote: I think my question is more oriented towards PHP, but I'd like to ask it on this list, as I suspect the solution may involve MySQL. I'm about to start developing an enormous database focusing on the animal kingdom and want to find a key system more user friendly than the traditional scientific name. So imagine instead a page with the following in the head section: $AnimalID = 'canlup'; This page displays information on the wolf, based on the first three letters of its genus and species name, Canis lupus. Now imagine a page with this value: $AnimalID = 'bal'; This page displays information on the whale family Balaenidae. But what about the whale family Balaenopteridae, which begins with the same three letters? I could solve this problem by adding a numerical key to my database and displaying the following: $AnimalID = 'bal23'; $AnimalID = 'bal24'; The problem with this is that it makes it much harder to work with my data. When tweaking a page or writing a script, I can easily remember that bal = Balaenidae, but I can't possibly remember which numeral is associated with each mammal family. Also, what happens if I add or subtract rows from my database table, and the above values suddenly change to bal27 and bal28? So here's what I think I'd like to do: $AnimalID = 'canlup1'; $AnimalID = 'bal1'; $AnimalID = 'bal2'; The page with canlup1 will display the FIRST (and only) instance of canlup in the database - the wolf. The page with bal1 will display the first instance of bal, which will always be Balaenidae, whether the absolute value is bal27 or bal2884. A page with bal2 will always display the next mammal family that begins with bal, Balaenopteridae. So I THINK all I need to do is create a variable that reflects a particular value's ordinal position in a database... abc1 abc2 abc3, etc. Plus, I'll have to join two or three fields together to form a key; e.g. animals.species + animals.numerals Does anyone know how I can do this?

If I create a new page that focuses on the king salmon, I'd rather type in $MyID = 'onc'; than $MyID = 'Oncorhynchus'.

Re: Relative Numeric Values
David, In reading through miscellaneous database design text on the web, I read just the other day that you should not try to include meaningful data in your key values. I assume there will be some kind of "lookup" tables for species, phylum, whatever. Trying to make your key field "smart" seems like way too much overhead and complexity.

Re: MySQL bottleneck
None taken, I'm sure it's a vague question but I had to start somewhere. I'm not an expert on anything that large as of today. 1) Is the data entered once and than mostly read access or is it frequently updated ? It's entered once but mostly(almost ALL 99%) read access. 2) Do you need transaction support ? No 3) Do you need the data to be EASY transferable between different OS (MAC/WIN/Unix/Linux) ? No BTW: You posted into somebody elses thread (which is not polite). I suggest you think about the above questions and start a new topic again. How did I do that? I'm using this hotmail account which is acting really strange to begin with and I've posted any message directly to [EMAIL PROTECTED] If that posts to someone else's thread That's weired, I can't even GET any threads other then my own on this account. I thought I would actually try filling up MS mail servers with this list instead of my own but it looks like I only get my own threads and they come via user email not mysql@lists.mysql.com so If that happened I appologize and will be more then happy to just dump this account if it happens this time. 4> basically the main thing in the application is password authentication then when the user is authorized their homepage is but from a handfull of variables from the database.

Relative Numeric Values
I think my question is more oriented towards PHP, but I'd like to ask it on this list, as I suspect the solution may involve MySQL. I'm about to start developing an enormous database focusing on the animal kingdom and want to find a key system more user friendly than the traditional scientific name. So imagine instead a page with the following in the head section: $AnimalID = 'canlup'; This page displays information on the wolf, based on the first three letters of its genus and species name, Canis lupus. Now imagine a page with this value: $AnimalID = 'bal'; This page displays information on the whale family Balaenidae. But what about the whale family Balaenopteridae, which begins with the same three letters? I could solve this problem by adding a numerical key to my database and displaying the following: $AnimalID = 'bal23'; $AnimalID = 'bal24'; The problem with this is that it makes it much harder to work with my data. When tweaking a page or writing a script, I can easily remember that bal = Balaenidae, but I can't possibly remember which numeral is associated with each mammal family. Also, what happens if I add or subtract rows from my database table, and the above values suddenly change to bal27 and bal28? So here's what I think I'd like to do: $AnimalID = 'canlup1'; $AnimalID = 'bal1'; $AnimalID = 'bal2'; The page with canlup1 will display the FIRST (and only) instance of canlup in the database - the wolf. The page with bal1 will display the first instance of bal, which will always be Balaenidae, whether the absolute value is bal27 or bal2884. A page with bal2 will always display the next mammal family that begins with bal, Balaenopteridae. So I THINK all I need to do is create a variable that reflects a particular value's ordinal position in a database... abc1 abc2 abc3, etc. Plus, I'll have to join two or three fields together to form a key; e.g. animals.species + animals.numerals Does anyone know how I can do this?

Database load and table design ?
Hello, Currently I am using syslog-sql to store syslog data in a mysql database. The table format is something like: ID hostnamefacilityprioritydatemessage ID is auto incrementing Now I am writting a perl app to calculate stats based on the data in the table which will get run everyday. It is currently doing a loop, here is an example: Select count(facility) from syslog WHERE machine = '$srv' AND facility = '$fac' AND date1 > (NOW() - INTERVAL 24 hour) Now $srv is the name of the host and $fac is the facility name. This select statement is in a loop that loops through each server and each facility. When this is running it puts a load on the DB, since there could be about 20 host, each with 6 facilities, which equals about: 600 - The number of times that the select statement would be run I suppose that running the query: select host,facility from WHERE date1 > (NOW() - INTERVAL 24 hour) and letting perl do the math on the selected results would be less of a system load ? Is there a better way ? Also I am going to display the results using the following format: hostnamehost A host B ... Facility name facility A X XX facility B X xX facility C X XX Is there an easy way to put that into a mysql table ?? Thanks.

Re: Size of BLOB types?

For that you'd have to ask MySQL. As to why there's a "TINY" - again I'm assuming, but I'd expect if someone has a lot of small binary data elements to store, they wouldn't necessarily want to waste 1K, or 65K of disk space for each element. Just because you have no use for it doesn't mean others don't.

Include repeats in query
Hi, I have the following query: SELECT person FROM people WHERE ORDER BY RAND() * (1 / score) LIMIT 1 This returns a person randomly, but the chance of the person being selected is increased with a higher `score`. What I want to do is make a single query that will return 10 results in this fashion. Currently I'm doing: for (i = 1; i <= 10; i++) do: SELECT person FROM people WHERE ORDER BY RAND() * (1 / score) LIMIT 1 Which returns a results like: Mike Sam Sam Mike Mike Mike John Sam Mike John This is exactly the result I desire, but programmatically it's not the most efficient way. I'm guessing using 1 query and using the result set is MUCH faster, 1 query... 1 result, instead of 10. I have tried: (SELECT person FROM people WHERE ORDER BY RAND() * (1 / score) LIMIT 1) UNION (X) UNION (X) ... [repeat ten times] This however returns this kind of result: Mike Sam John The UNION query seems to remove the repeats, and because this is a mathematical system this will throw it out. This of course is not what I want :-(. Is there an option that allows repeats? Cheers, - Martin
