Struct polkadot_runtime_parachains::scheduler::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn validator_groups() -> Vec<Vec<ValidatorIndex>>

All the validator groups. One for each core. Indices are into ActiveValidators - not the broader set of Polkadot validators, but instead just the subset used for parachains during this session.

Bound: The number of cores is the sum of the numbers of parachains and parathread multiplexers. Reasonably, 100-1000. The dominant factor is the number of validators: safe upper bound at 10k.

impl<T: Config> Pallet<T>

pub fn availability_cores() -> Vec<Option<CoreOccupied>>

One entry for each availability core. Entries are None if the core is not currently occupied. Can be temporarily Some if scheduled but not occupied. The i’th parachain belongs to the i’th core, with the remaining cores all being parathread-multiplexers.

Bounded by the maximum of either of these two values:

The number of parachains and parathread multiplexers
The number of validators divided by configuration.max_validators_per_core.

impl<T: Config> Pallet<T>

pub fn session_start_block() -> T::BlockNumber

The block number where the session start occurred. Used to track how many group rotations have occurred.

Note that in the context of parachains modules the session change is signaled during the block and enacted at the end of the block (at the finalization stage, to be exact). Thus for all intents and purposes the effect of the session change is observed at the block following the session change, block number of which we save in this storage value.

impl<T: Config> Pallet<T>

pub fn scheduled() -> Vec<CoreAssignment>

Currently scheduled cores - free but up to be occupied.

Bounded by the number of cores: one for each parachain and parathread multiplexer.

The value contained here will not be valid after the end of a block. Runtime APIs should be used to determine scheduled cores/ for the upcoming block.

impl<T: Config> Pallet<T>

pub fn add_parathread_claim(claim: ParathreadClaim)

Add a parathread claim to the queue. If there is a competing claim in the queue or currently assigned to a core, this call will fail. This call will also fail if the queue is full.

Fails if the claim does not correspond to any live parathread.
