Time to Live(TTL) node support #4895
Description
Experience Report
What you wanted to do
I wanted to set a TTL on nodes. The data we are persisting in Dgraph has a very definite life span, so being able to configure a TTL per dgraph.type would be really useful.
I also feel that TTL is a fundamental requirement, that would be useful for a lot of the Big Data domains that Graph DBs are central to solving.
What you actually did
Nothing. If this feature is not natively supported, we would need to write some custom code to execute periodically to delete nodes via mutation.
Why that wasn't great, with examples
(have not attempted a workaround solution, yet. as project not at stage where this is needed)
