snapsnapdown is a Snapchain Snapshot Downloader.

I wrote it because I had some issues when I was setting up my node.

It gives you more flexibility than the embedded downloader:

- You can stop/start and it will pick up where you left.

- When restarting, local chunk sizes will be compared to remote, and if they do not match they will be re-downloaded

- Concurrent chunk downloads: I have found that sometimes a chunk may download at very low speeds, having concurrent downloads removes the bottleneck and results in faster overall download.

- Downloaded chunks are not automatically deleted.

- It looks nicer :-)

It doesn't have to be everything in one monolithic container. Actually, you may want to consider moving the rust "downloader" to a separate tool.

- This is how you start your node.
- If you don't want to start from zero, use this command to download a snapshot, before starting the node.

Very cool. If this was in rust, we'd merge it into snapchain :)

We're working on improving this, but thank you for building this in the meantime.

My personal tests show that having concurrent downloads can significantly decrease the overall download time. (My tests have shown even -50%, but this may be due to my connection/hardware/network.)

Do you know if it’s possible to read the rocksdb output if it hasn’t completed syncing yet?

There is an extract subcommand, but it's very rough. The README has details on how to do it with tar.

Really nice, ty!

Does it know how to extract the chunks?

omg i was planning on making something like this myself, love it!!! thanks for open sourcing!
