# polkadot-du

Investigate storage size of Substrate chains.

Install with: 

```sh

cargo install polkadot-du

pdu --help

```

### 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](https://paritytech.github.io/try-runtime-cli/try_runtime/) for this and a

full or archive node to download the state from:

```sh

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

```

Then run the analysis:

```sh

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](https://tasty.limo/kusama.snap) to try it.

You can also zoom in on a specific pallet:

```sh

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

```

Again for Kusama:
