async fn node_epoch_above_record(
kv_backend: &KvBackendRef,
node_id: u64,
start_time_ms: u64,
) -> Result<u64>Expand description
Returns the epoch of this process: its start time, or one more than the epoch the metasrv has recorded for the node when the record is not lower than the start time, as after a restart on a slower clock or after the clock stepped back. The metasrv fences an epoch lower than the recorded one.
