Expand description
Scheduler configuration parameters. All coretime/ondemand parameters are here.
Fields§
§group_rotation_frequency: BlockNumber
How often parachain groups should be rotated across parachains.
Must be non-zero.
paras_availability_period: BlockNumber
Availability timeout for a block on a core, measured in blocks.
This is the maximum amount of blocks after a core became occupied that validators have time to make the block available.
This value only has effect on group rotations. If backers backed something at the end of
their rotation, the occupied core affects the backing group that comes afterwards. We limit
the effect one backing group can have on the next to paras_availability_period
blocks.
Within a group rotation there is no timeout as backers are only affecting themselves.
Must be at least 1. With a value of 1, the previous group will not be able to negatively affect the following group at the expense of a tight availability timeline at group rotation boundaries.
max_validators_per_core: Option<u32>
The maximum number of validators to have per core.
None
means no maximum.
lookahead: u32
The amount of blocks ahead to schedule paras.
num_cores: u32
How many cores are managed by the coretime chain.
max_availability_timeouts: u32
Deprecated and no longer used by the runtime. Removal is tracked by https://github.com/paritytech/polkadot-sdk/issues/6067.
on_demand_queue_max_size: u32
The maximum queue size of the pay as you go module.
on_demand_target_queue_utilization: Perbill
The target utilization of the spot price queue in percentages.
on_demand_fee_variability: Perbill
How quickly the fee rises in reaction to increased utilization. The lower the number the slower the increase.
on_demand_base_fee: Balance
The minimum amount needed to claim a slot in the spot pricing queue.
ttl: BlockNumber
Deprecated and no longer used by the runtime. Removal is tracked by https://github.com/paritytech/polkadot-sdk/issues/6067.
