database - Generating a massive 150M-row MySQL table -

-

I have a C program, which is a huge data source (20 GB raw text) to mine and is simple to perform on for the empty table INSERTs generate the load (1 to 4 integer column primary key). A MEMORY as the table in the setup, the entire work is to be completed in 8 hours. After finishing in the table, there are approximately 150 million rows. Eight hours for me is the number of a fully civilized. This is a one-time deal.

The problem occurs when the MEMORY table to return MyISAM tries to change is that (a) I Other processes for memory to free has been, and (b) when I restart the computer I will not kill you data. 

  ALTER TABLE memtable ENGINE = MyISAM

I have two days to the Optional table query run has, and it it is not. I now it has killed

If I was starting in the meyajama as table'm making, the writing speed is too bad there is (especially due to the fact that the query as Duplicate of key update require the use of technology). I can not stop temporarily the keys will be 1000 times larger than the table and then if I start I need the keys again and must be run by a group of 150,000,000,000 lines. Umm, no

to feel the major obstacles in the one: INSERT query record updates if the table has a primary key (a hash) already exists

maisasama strictly try to use the beginning, I have 1,250 lines per second, the speed of getting a fat. The index increased after, I think that this rate will be even more tanks.

I have 16 GB of memory is installed in the machine. A large table is the best way to generate a drive that eventually, as indexed in MyISAM table is finished?

Explanation: There are a lot of updating queries ( INSERT ... val = val + duplicate key update any ) . It is a way, a raw dump is not a problem. For the first time in a MEMORY to the table to try to change my argument that all the index lookup, and the table-are for each INSERT, was for.

For you to comment on (the last one, probably) Sorry for throwing.

I just got a big table to change is an example of offers misama the inodibi up, while this is not what you are, it is a intermediate storage of table uses and an efficient way of storage memory is used to describe - how to sort the table in memory that InnoDB is hope that in the end it has to be ordered. If you are not tied to maissama you already have a "right" storage table, because it is a value as can be.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
