Will versioning consume the 4MB DataStore quota?

Once DataStore Versioning was implemented recently, I wonder if the additional data saved in each version will consume the 4MB DataStore quota?

If so, this could be dangerous, as a change to a large table using SetAsync will duplicate this table in each version of the DataStore and take up more and more space within the available 30 days.

Good question!
The answer is no, it doesn’t count towards the quota.

Test Script:

local DataStoreService = game:GetService("DataStoreService")
local store = DataStoreService:GetDataStore("test")

local key = "big"

store:SetAsync(key, string.rep("a",4100000))
print("set a string")

store:SetAsync(key, string.rep("b",4100000))
print("set b string")

local versions :DataStoreVersionPages = store:ListVersionsAsync("big")
for _,v :DataStoreObjectVersionInfo in pairs(versions:GetCurrentPage()) do
	local good,str = pcall(function()
		return store:GetVersionAsync(key, v.Version)
	if not good then warn(str) end
	print("FirstLetter",str:sub(1,1),"strln",str:len(),"Time", v.CreatedTime, "version", v.Version)

Result (I ran it a few times lol):
