remote-externalities: 'instant' snapshots, threading refactor, better progress logs #14057

liamaharon · 2023-05-01T12:19:54Z

Instant(ish) snapshot loading

The existing snapshots contain key / values without the trie. Loading the key/values can take a while even when batch inserting because the trie needs to be re-computed.
In this PR, the snapshot was refactored to contain the raw trie itself, and be loaded directly into the underlying TrieBackend storage that backs TestExternalties

Snapshot load performance (Macbook Pro M2 Max)

Chain	Build	Before	After	Improvement
Kusama	debug	12.13s	0.88s	92.75%
Kusama	release	1.93s	0.18s	90.67%
Polkadot	debug	59.08s	2.66s	95.50%
Polkadot	release	8.25s	0.44s	94.67%

Removes threading

Uses async/await futures for parallel requests instead of threads
Closes try-runtime-cli panics on Polkadot #14006
It makes loading state from a live node a little bit slower because it waits until all data has been downloaded before loading it into the trie. However, the degradation is small, and it should be encouraged to use snapshots instead when performance is required especially now that we have much faster snapshot loading.
Bonus: simplifies a lot of complex code

Better progress logs

Spinner for operations where the eta cannot be estimated
Progress bar for operations where the eta can be estimated
Partial try-runtime-cli: polish output #13975

nice, LGTM

Can you add an example of the changed CLI output in the PR description so the reviewers can a feeling how output will look like after this change?

Converting this to a draft, I'd like to include a switch to inserting keys directly into OverlayedChanges into this PR.

This reverts commit c0ddb87.

This reverts commit 1d49362.

This reverts commit 06df786.

Tested it for all four parity nodes and it works with this patch, thanks!

kianenigma

It looks very promising!

I think now's a good time to revisit https://github.com/paritytech/devops/issues/2083 and its importance as well.

With the end goal of making this usable (in a stable and fast way 🙈) in our CI, it would make a lot of sense to have snapshots ready in our infra, and have the CI use those. With this fast loading time, it would be a smooth process.

It is pretty fast now. Takes about 3 minutes locally and 15 in CI.
I think we should rather focus on stability and add tests instead of optimizing more.

Looks pretty good, thanks!

@ggwpez utils/frame/remote-externalities/test_data/proxy_test is a snapshot file used in a test. I needed to update it to use the new snapshot format.
