Documentation about how Badger actually stores Dgraph data on disk

Thanks for the reply, the debug tool is quite helpful!

If I use a badger command line, can i access a locked folder? or i still need to shut down the alpha in order to have a look?

Also, I’m wondering if there is anyone from the core team that could take time to answer this thread:

Querying for historical values, and creation and modification timestamps as dateTime

I read that dgraph is configuring badger to keep all value mutations in the log permanently: options.NumVersionsToKeep . We set this by default to 1 in Badger, but in Dgraph, we set this to infinity So… My question is, can we access that “infinite history” via dgraph queries? I am experimenting with adding explicit created and modified dateTime predicates, but it feels like this could/should be provided via an implicit function of some sort. Intuitively i would like this kind of query: { …

Now (thanks to the debug tool) I can see that the infinite history is there, and I’d love to have easy access to it (without having to create additional dgraph structures for it)
