Struct MemtableStats 

Source 
pub struct MemtableStats {
    pub estimated_bytes: usize,
    pub time_range: Option<(Timestamp, Timestamp)>,
    pub num_rows: usize,
    pub num_ranges: usize,
    pub max_sequence: SequenceNumber,
    pub min_sequence: SequenceNumber,
    pub series_count: usize,
}

Fields§

§estimated_bytes: usize

The estimated bytes allocated by this memtable from heap.

§time_range: Option<(Timestamp, Timestamp)>

The inclusive time range that this memtable contains. It is None if and only if the memtable is empty.

§num_rows: usize

Total rows in memtable

§num_ranges: usize

Total number of ranges in the memtable.

§max_sequence: SequenceNumber

The maximum sequence number in the memtable.

§min_sequence: SequenceNumber

Lower bound of the row sequences written to this memtable or range. May remain below the actual minimum after deduplication. Zero is conservative when a range does not track its minimum; the value is unused for empty memtables.

§series_count: usize

Number of estimated timeseries in memtable.
