Key Operations
Storage Metering
// Track upload size
func RecordUpload(userID string, size int64) error {
usageMeter.UpdateStorage(userID, size)
quota.CheckExceeded(userID)
}
Job Slot Allocation
// Allocate job slot
func AllocateJobSlot(companyID string) error {
if !quota.Available(companyID) {
return ErrQuotaExceeded
}
return jobSlot.Allocate(companyID)
}
Capacity Pack Purchase
// Process pack purchase
func PurchaseCapacityPack(userID string, packType string) error {
pack := GetPack(packType)
quota.Increase(userID, pack.Storage, pack.Bandwidth)
charge := ChargeRecord{
UserID: userID,
Amount: pack.Price,
Type: "capacity_pack",
}
return charges.Save(charge)
}
