Struct MaintenanceReport 

pub struct MaintenanceReport {
    pub time_spent: Duration,
    pub completed_merges: Vec<PathBuf>,
    pub rows_merged: u64,
    pub bytes_written: u64,
    pub pending_compaction: bool,
    pub dropped_whole: Vec<PathBuf>,
}

Maintenance report from a maintenance_step() call (M5.2, Issue #384)

Fields

time_spent: Duration

Time spent in this maintenance step

completed_merges: Vec<PathBuf>

Completed merge output files (if any merge completed)

rows_merged: u64

Number of rows merged in this step

bytes_written: u64

Number of bytes written in this step

pending_compaction: bool

Whether there is pending compaction work

dropped_whole: Vec<PathBuf>

SSTables DROPPED WHOLE by the fully-expired fast path in the merge that completed this step (issue #1388), distinct from the merged inputs: each was proven fully expired by authoritative Statistics.db metadata and overlap-safe, so it was excluded from the K-way merger (never read/decoded) and its components were reclaimed after the merged output published. Empty when nothing was dropped. Paths are input Data.db paths.
