Ask HN: Looking for query language for Chrome DevTools heap snapshot?

While coding in the nodejs from time to time there are memory leaks, and good tool to find those leaks is the Chrome DevTools heap memory snapshot. On the other hand finding problem requires somewhat tedious job to identify a memory leak that is from the app and not supporting library. It would be awesome if there was an ability to do "SQL search" through those, it would be possible to "group by" instances by the same line, which would increase ability to quickly pin point where is the problem. Also it would be possible to reorganize entire structure by sizes etc. Has anyone worked with any similar tool?
