Thanks to enormous work done by Łukasz ‘metys' Lewandowski, explain.depesz.com page is no longer “desiged by depesz" (which is a code for “ugly as hell"), but is nice, and good looking.
If you like it, please do send some thank you note to Łukasz – he blogs in Polish, but he reads and understands English too.
Change is not only skin deep. The whole site has been rewritten, and uses now Mojolicious web framework instead of Catalyst.
This change should be a welcome surprise to anyone willing to setup their own copy of the site for top-secret plans from their company – mostly because number of dependencies dropped significantly.
All in all – have fun, and thanks for using the site.
I just updated explain.depesz.com with bugfix, which changes the way Bitmap Index Scan and Bitmap Heap Scan are displayed. Apparently index and table names were not shown previously.
Thanks go to Viktor Rosenfeld for spotting and reporting the bug.
I just updated explain.depesz.com with 2 new interface features:
- When you put mouse cursor over node, it will mark direct child nodes with
- When you click on node, all child nodes (even indirect) will be hidden, and the node you clicked on will be marked with
Both features are directed towards people who analyze longer plans – ability to hide parts or just visually see what the Nested Loop is calling in 2nd stage greatly helps me see the flow of query – you can test it, for example, here.
By the way – BIG THANK YOU for Metys for help on it (well, actually, for doing it).
I just modified the internals of explain.depesz.com. Now, it finally stores the plans in database (previously it stored the plans as files in dedicated directory).
Effect for enduser is just that history page should load faster.
But, having the data in database makes it possible to add more features.
One such feature is already added – ability to explain plan, but not list it on history page.
Right now, when you add new plan, you can specify if you want it to be listed with other previous explains – default value is “yes". But if you don't want just anybody to be able to click his way to your plan – there is option for it.
For obvious reasons all previous plans are marked as public now. If you want it to be changed, please contact me – we can probably do something about it.
And as last thing: I would like to express my big THANK YOU to all of you who use explain.depesz.com.
(side note: Catalyst is really cool)
