Implementations§

Source§

impl Level

Source

fn recompute_size(&mut self)

Source

fn normalize(&mut self)

Remove SSTs with empty table_ids, then recompute sizes.

Source

fn delete_ssts(&mut self, ids: &HashSet<HummockSstableId>) -> bool

Return true if any SST was actually removed.

Source

fn truncate_tables(&mut self, table_ids: &HashSet<TableId>)

Truncate specified table_ids from each SST’s metadata, remove SSTs that become empty, then recompute sizes.
