Changes needed to implement the runtime part of elastic scaling: https://github.com/paritytech/polkadot-sdk/issues/3131, https://github.com/paritytech/polkadot-sdk/issues/3132, https://github.com/paritytech/polkadot-sdk/issues/3202 Also fixes https://github.com/paritytech/polkadot-sdk/issues/3675 TODOs: - [x] storage migration - [x] optimise process_candidates from O(N^2) - [x] drop backable candidates which form cycles - [x] fix unit tests - [x] add more unit tests - [x] check the runtime APIs which use the pending availability storage. We need to expose all of them, see https://github.com/paritytech/polkadot-sdk/issues/3576 - [x] optimise the candidate selection. we're currently picking randomly until we satisfy the weight limit. we need to be smart about not breaking candidate chains while being fair to all paras - https://github.com/paritytech/polkadot-sdk/pull/3573 Relies on the changes made in https://github.com/paritytech/polkadot-sdk/pull/3233 in terms of the inclusion policy and the candidate ordering --------- Signed-off-by: alindima <alin@parity.io> Co-authored-by: command-bot <> Co-authored-by: eskimor <eskimor@users.noreply.github.com>
The Polkadot Parachain Host Implementers' Guide
The implementers' guide is compiled from several source files with mdBook.
Hosted build
This is available here.
Local build
To view it locally, run the following (from the polkadot/ directory):
Ensure graphviz is installed:
brew install graphviz # for macOS
sudo apt-get install graphviz # for Ubuntu/Debian
Then install and build the book:
cargo install mdbook mdbook-linkcheck mdbook-graphviz mdbook-mermaid mdbook-last-changed
mdbook serve roadmap/implementers-guide
and in a second terminal window run:
open http://localhost:3000
