====================
PEV2 is a graphical visualization tool to understand PostgreSQL execution plans.
*Why PEV2?*
You probably already know the simple yet excellent Depesz. You may also have heard about PEV which is popular as well and it’s deserved.
The latter is a really great tool in my opinion but unfortunately it hasn’t been actively maintained for more than 3 years now.
While searching for a javascript library to display an execution plan into a monitoring tool (temBoard), I wanted to check if PEV could make a good candidate. It was unfortunately impossible to use it as is. It seemed abandoned and didn’t fully match my needs.
Thus I quickly decided to fork it. With great and quick success, given the fact that it was really well written. Kudos to its author.
To make it very quick, the new project is written using webpack, VueJS, Typescript, Bootstrap.
*Its main features*
* PEV2 is able to parse an execution plan in the default format returned by EXPLAIN (ie. text),
* it highlights the most relevant values for duration, cost and row estimation factor,
* you can choose the way the graph is displayed: 2D or classic.
As the tool is improving quickly, many more features are still to come!
