Remove discarded blocks and states from database by default #11983

hzy1919 · 2022-08-05T09:28:57Z

Fixes #11912

1.Add state_pruning's sub-param archive-canonical in sc-cli.
2.Change blocks_pruning to be like state_pruning : use the string archive for BlocksPruning::KeepAll and archive-canonical(and default) for BlocksPruning::KeepFinalized and then a number of BlocksPruning::Some(x).

polkadot companion: paritytech/polkadot#5992
cumulus companion: paritytech/cumulus#1613

Closes: #12094

2.Make PruningMode's default value to ArchiveCanonical.

"canonical" is more of an internal concept, and not a user friendly term. Let's call it "final" or "finalized"

Ok , Let's set it "final".

arkpar · 2022-08-09T17:45:13Z

There's no need to change the defult pruning mode. It should remain at 256 block history.

arkpar · 2022-08-09T17:49:08Z

Regarding #11912, adding a CLI for ArchiveCanonical only fixes it half way. The major piece of work required here is to remove block bodies, and not just state. This part is a bit more involved.

Well , I'll rethink where to start...

Hey, is anyone still working on this? Due to the inactivity this issue has been automatically marked as stale. It will be closed if no further activity occurs. Thank you for your contributions.

… Corresponds to `blocks_pruning 0` in CLI . 2.Change value `All` to `AllFinalized` in `enum BlocksPruning` and make it to keep full finalized block history.

Looks good with some minor comments. One addition that's also required here, is that prune_block function also deletes justification data.

		utils::remove_from_db(
			transaction,
			&*self.storage.db,
			columns::KEY_LOOKUP,
			columns::JUSTIFICATIONS,
			id,
		)?;

Done.

Looks good to me. Just got some question suggestion for the Cli and maybe using different names, but did not really have any good ideas.

In the doc there is also a "archive-canonical" mention that did not look linked, I would maybe use it instead of "final".
But tbh I did not find a good name. Since it is the new default it should be shorter or more attractive than 'archive', but 'final' is not really saying much to me.
If anybody got other ideas?
(ideally former 'archive' becomes 'archive-all' and 'final' wil be 'archive', but it breaks compatibility)

Yeah, it should be called archive-canonical

Here we should add that 0 keep all blocks.
Generally this is not very intuitive.
Maybe we should do something like state_pruning: use the same string: 'archive' for 'keep_all' and 'final' fo 'keep_finalized'. (subject to change of name too).

Hmm,,It's really not very intuitive that 0 keep all blocks. IMO it's a compromise approach now.
I agree that change blocks_pruning to be like state_pruning.

May be worth mentioning in release note that justification are now pruned with block (additionally to the new parameters).
But looks like a good thing to me 👍

Okay that is relative random. That this switches to KeepAll when you give it 0.

Maybe we should not expose KeepAll at all. Or we really need to introduce some new cli flag.

what do you think about that change blocks_pruning to be like state_pruning : use the string keep-all for BlocksPruning::KeepAll and keep-finalized(and default) for BlocksPruning::KeepFinalized ?
And IMO ,It may help to keep the style consistent with state_pruning and be better to be understood .

Using same naming would be good IMO.

That also be OK .

Sounds good.

Looks good. Could also use a companion PR to the polkadot repo. See here: https://github.com/paritytech/substrate/blob/master/docs/CONTRIBUTING.adoc#updating-polkadot-as-well

yeah, I added before. :D

Can we not just change new_test_with_tx_storage to take BlocksPruning by default?

Hmm,,I think that will work too.
