§Pallet Broker
Brokerage tool for managing Polkadot Core scheduling.
Properly described in RFC-0001 Agile Coretime.
§Implementation Specifics
§Core Mask Bits
This is 1/80th of a Polkadot Core per timeslice. Assuming timeslices are 80 blocks, then this indicates usage of a single core one time over a timeslice.

Modules§
- The
pallet
module in each FRAME pallet hosts the most important items needed to construct this pallet. - Runtime API definition for the FRAME Broker pallet.
- Autogenerated weights for
pallet_broker
Structs§
- Result of
AdaptPrice::adapt_price
. - A record containing information regarding auto-renewal for a specific core.
- Simple implementation of
AdaptPrice
with two linear phases. - Configuration of this pallet.
- The record body of a Region which was contributed to the Instantaneous Coretime Pool. This helps with making pro rata payments to contributors.
- A per-timeslice bookkeeping record for tracking Instantaneous Coretime Pool activity and making proper payments to contributors.
- Information on a single legacy lease.
- Record for On demand core sales.
- A record of flux in the InstaPool.
- The identity of a possibly renewable Core workload.
- A record of a potential renewal.
- Self-describing identity for a Region of Bulk Coretime.
- The rest of the information describing a Region.
- The status of a Bulk Coretime Sale.
- Performance of a past sale.
- An distinct item which can be scheduled on a Polkadot Core.
- General status of the system.
Enums§
- How much of a core has been assigned or, if completely assigned, the workload itself.
- An element to which a core can be assigned.
- Whether a core assignment is revokable or not.
Constants§
- The number of bits in the
CoreMask
.
Traits§
- Type for determining how to set price.
- Type able to accept Coretime scheduling instructions and provide certain usage information. Generally implemented by the Relay-chain or some means of communicating with it.
Type Aliases§
- Index of a Polkadot Core.
- Counter for the total number of set bits over every core’s
CoreMask
.u32
so we don’t ever get an overflow. This is 1/80th of a Polkadot Core per timeslice. Assuming timeslices are 80 blocks, then this indicates usage of a single core one time over a timeslice. - Record for Polkadot Core legacy leases.
- Fraction expressed as a nominator with an assumed denominator of 57,600.
- Relay chain block number of
T
that implementsCoretimeInterface
. - Relay chain block number provider of
T
that implementsCoretimeInterface
. - Record for Polkadot Core reservations (generally tasked with the maintenance of System Chains).
- The same as
CoreMaskBitCount
but signed. - A Task Id. In general this is called a ParachainId.
- Relay-chain block number with a fixed divisor of Config::TimeslicePeriod.
