Problems

Implement ur own weak cache may be kinda ugly, specialy if ur cache have 2 keys/layers/dimensions, as u can see here

local cache = setmetatable({}, { __mode = 'k' })

local function awaitCombatSession(player1: Player, player2: Player)
    
    if cache[player1] and cache[player1][player2] then return cache[player1][player2]:expect() end
    if cache[player2] and cache[player2][player1] then return cache[player2][player2]:expect() end
    
    local promise = Promise.new(coroutine.yield)
    cache[player1] = cache[player] or setmetatable({}, { __mode = 'k'})
    cache[player1][player2] = promise
    
    --// Instance
    local data = someYieldingFunction()
    local self = {}
    
    promise:_resolve(self)
    return promise
end

Solution

--// Vars
local cache = Cache.async(-1, 'k', 'k')
-- setmetatable({
--     [player1] = setmetatable({ [player2] = CombatSession }, { __mode = 'k' })
-- }, { __mode = 'k' })

--// Component
local function CombatSession(player1: Player, player2: Player)
    
    --// Instance
    local data = someYieldingCall()
    local self = {}
    
    --// End
    return self
end
local function CombatSessionAsync(player1: Player, player2: Player)
    
    return cache:findFirstPromise(player1, player2)
        or cache:findFirstPromise(player2, player1)
        or cache:promise(function() awaitCombatSession(player1, player2) end)
end
