# Schema: Polkadot SDK PRDoc Schema (prdoc) v1.0.0 # See doc at https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/prdoc/schema_user.json title: Add `availability-distribution` and `biftield-distribution` subsystem benchmark doc: - audience: Node Dev description: | The new subsystem benchmark test objective (`DataAvailabilityWrite`) is designed to stress test the part of the pipeline that takes as input a backed candidate and then distributes it as erasure coded chunks to other validators. The test pulls in the `av-store`, `bitfield-distribution` and `availability-distribution` subsystems while the whole network and rest of the node subsystems are emulated. crates: [ ]
