BACKGROUND : We had a table in one of our databases that served as a “hopping” point for some jobs. Data was inserted into this table and at jobs get kicked off at periodic intervals to “process” the data and delete it.

CURRENT METHOD : Launch multiple jobs to process the data and delete the rows as soon as the data is processed. This is causing locks on the table because there are multiple delete operations occurring at the same time. Which in turn means that the jobs cannot complete processing the data causing the table to grow in size.

PROPOSED METHOD : Add a new column to the table called “PROCESSED_STATE” and modify the “processing” jobs to set a flag “Y” in this column as soon as the data is processed. Create a new job that will be launched periodically, which checks the PROCESSED_STATE column and if the flag is set to “Y”, deletes the row.

Morale of the story.. .. Multiple deletes on a table are bad. Better way is to have multiple updates and one delete.

And traffic to the site drops!!

Things have been a bit crazy at work recently, so I didn’t get a chance to fix the site as soon as it went down (due to an error I still haven’t figured out). And as a result, the traffic to the site dropped.

I finally took the chance to move the site to a dedicated server running on the RackSpace Cloud services. Am putting together a post on how I handled this migration and will publish it soon.

The bad news is that I have lost traffic to the site that I have built over a period of time.. the good news is that I am the master of my own house (website) at last .

Check out this article on ReadWriteWeb regd how the tech leaders are calling for a boycott of Facebook and advocating for an open social networking protocol (http://www.readwriteweb.com/archives/more_web_industry_leaders_quit_facebook_call_for_o.php).

Another article on the same website, speaks about a study by the Advanced Institute of Science and Technology in Korea, which shows that Twitter is really not a social networking site, but more of a medium to broadcast your content (http://www.readwriteweb.com/archives/study_twitter_isnt_very_social.php). Doesn’t really support the argument I made earlier that Twitter is not going to make it..but it certainly supports the notion that once the hype is gone the influence of twitter as a medium will decrease.
