I need to write a Web interface to a PostgreSQL database and I am considering to use Twisted for that. So, I have a few questions. First of all, I would like to know if there already something available that I should look at. Second, I have a more specific question. Suppose I have a large table with 1,000,000 records and a SELECT query that returns 1000 results and takes 10 minutes. I don't want my users to wait. I want to display the result of the query as an HTML table of 50 rows. The user should click, wait 30 seconds, see the result, then click a 'next' button to see the other 50 results, etc. In other words, I am looking for a lazy query functionality. Is that already available? If not, is it easy/difficult to implement? Thanks for any suggestion, Michele Simionato
