From Parity Ethereum Documentation:

Warp Sync is an extension to the Ethereum Wire protocol, which involves sending snapshots over the network to get the full state at a given block extremely quickly, and then filling in the blocks between the genesis and the snapshot in the background.

When I run parity --help for Parity v1.11.4, the bullet about warp says:

    Does nothing; warp sync is enabled by default.

That said, is there any advantage left in setting pruning=fast or pruning=light?

To my understanding, their purpose is to allow for a fast (but incomplete) sync.

But then, as mentioned above, warp seems to do that already.

So when exactly should I be using pruning to anything other than archive?

Thank you!
