google chrome - Why does empty IndexedDB still take up space? -


i'm using indexeddb saving game data in chrome.

an average game 4mb. after saving few games, , deleting them, dev console's 'resources' tab shows indexeddb empty, expected, if go content settings, "cookies , site data" it's showing me 12mb indexeddb size on disk.

this after refresh , restart of chrome. following code deletion , i'm getting success when delete , query old data returns nothing, expected.

database.indexeddb.deletegame = function(namein){     var db = database.indexeddb.db;     var trans = db.transaction(["saves"], "readwrite");     var store = trans.objectstore("saves");     var wipeslate = store.delete(namein);     wipeslate.onsuccess = function(e) {         console.log("old game wiped");     };     wipeslate.onerror = function(e) {         console.log("i don't think old game existed..." + e);     }; };

i've checked following questions (and search results aren't showing promising either):

but none of them deal my question, , appreciated.

chrome doesn't delete data disk, marked deleted. if write ~4 more megabytes indexeddb, leveldb compaction , files containing old entries deleted.

chrome has no 50mb limit , not ever ask user permission indexeddb.

this question may helpful. what storage limits indexed db on google's chrome browser?
