Investigate storage size of Substrate chains.

Example

First acquire a state snapshot. We are going to use the People Rococo chain, since it is rather small. You will need the try-runtime-cli for this and an archive node to download the state from:

try-runtime create-snapshot --uri wss://rococo-people-rpc.polkadot.io:443 rococo-people.snap

Then run the analysis:

cargo run --release -- --network rococo-people

The results will be a bit boring for such a small network, but for a larger one - eg Kusama - it could look like this. You can download this snapshot to try it.

You can also zoom in on a specific pallet:

cargo run --release -- --network rococo-people --pallet Balances

Again for Kusama:
