Is there a way to disable locking balance after sending to allow for sending rapidly from the monero-wallet-rpc?

no

make sure you have a lot of outputs in your wallet so that locking change doesn't become an issze

issue*

I'll add a second review to 8046 too I know this code well :) Will have it done by next week

moneromooo: any idea here? monero-project/monero #8243

I commented.

@selsta，sorry。If users send utxos to my subaddresses, when I want to spend them, do I need to specify which subaddresses the utxo is from, or do I just use a primary address?

You can select which output to spend with sweep_single. You don't have to though.

For example, this snippet of code. What does `accountIndex: 0` mean? Does it mean utxos only from the primary address? or only means the from address is the primary address and the utxos will be from all of my subaddresses?

Account index is... what it says. Subaddresses are defined by an account (32 bits) and an alias within an account (32 bit). Account index 0 means the first account, which is the default one, and this includes the wallet's standard address.

The "primary" (standard) address is a special case for backward compat. It's not a subaddress, but belongs to the first account.

And the 0,0 subaddress is not actually used, it's overridden by the standard address.

AFAIK, spending from account 0 will allow spending anyhting received to hte standard address as well as anything received to any subaddress in account 0.
