Struct WorkloadRecovery 

pub struct WorkloadRecovery {
    pub workload: String,
    pub node: String,
    pub subjects: BTreeMap<String, RecoveryRecord>,
    pub as_of: DateTime<Utc>,
}

Every measured subject for one workload, plus the clock reading that dates them.

as_of is captured at replay so that age_days is a pure function of already-read data: topology::analyze must not read a clock any more than it may read a file.

Fields

workload: String

node: String

The node the most recent measurement was taken on. Measurements taken on different machines are all kept; this names the latest, because a restore time is a property of a host as much as of a database.

subjects: BTreeMap<String, RecoveryRecord>

Last record per subject, ordered by subject name.

as_of: DateTime<Utc>

Wall clock at replay time.

Implementations

impl WorkloadRecovery

pub fn seconds(&self) -> f64

Total measured wall-clock seconds: the workload’s restore is all of its subjects, and the helper measures them one at a time.

pub fn bytes(&self) -> u64

Total measured bytes on disk after the restore.

pub fn measured_at(&self) -> DateTime<Utc>

When the summed figure was measured — the oldest component, because a sum is only as fresh as its stalest part.

pub fn age_days(&self) -> i64

Whole days between measured_at and as_of, floored at zero (a clock that went backwards is not negative age).

pub fn is_stale(&self) -> bool

Whether the headline must say the figure may no longer describe the declared state.

pub fn subject_count(&self) -> usize

How many subjects the summed figure covers.

pub fn helper(&self) -> &str

The helper that produced the most recent record.
