importaddress needs rescan or not to get balance?

Question

I am using importaddress to import an address into a node, then running getaddressbalance or getmultibalances to get the asset balances i need for that address. In the future as the chain gets larger, when would I need to use -rescan, or perhaps not needed if I I am doing is getting a balance?

Answer 1

Yes, if the address has been used before it is imported, you need a rescan to accurately update its balance. Note that you can make this more efficient by passing an array of addresses to importaddress.
