When executing a conventional data deletion command (the DELETE FROM statement), disk space is not immediately released. Instead, the data is marked first, and disk space is gradually freed by background tasks.
You can speed up this process by adjusting the parameters
inner_compaction_task_selection_disk_redundancyandinner_compaction_task_selection_mods_file_thresholdto smaller values.The database deletion command (the DROP DATABASE statement) can immediately release disk space.
