Knobs for one simulation run.

Fields

seed: u64

shards: u32

workflows: u32

duration_ms: u64

Simulated milliseconds of client activity with faults on.

crash_every_ms: u64

Mean simulated milliseconds between crashes (0 = never).

tear: bool

flush_fail_per_mille: u32

max_io_ms: u64

max_msg_ms: u64

park_after_ms: u64

checkpoint_interval_ms: u64

segment_bytes: u64

shared_log: bool

Log format 3: the shards share one log ([fusee::wal]); otherwise each has its own segments.

offload_bytes: u64

The shared log offloads records whose encoding is longer than this to its blob area (0: none). Low, so that ordinary records go there.

settle_ms: u64

Simulated milliseconds every acknowledged workflow gets to finish once faults stop.

user: Option<UserSetup>

A user scenario (crate::scenario) in place of the built-in workload.
