Describe the enhancement
Wallets with large last_revealed indexes are slow to generate the SPK cache when the wallet is loaded. I discovered this with a wallet that has an index of 7,000 addresses.
Use case
I am loading my wallets using the PersistTrait and this SPK list gets generated every time, which for large numbers is slow. I would like to load wallets from persistence as quickly as possible (so I can show the balance).
Additional context
There are a number of ways which were discussed in a call.
-
We can change KeychainTxOutIndex to persist the spks.
- needs to be careful to check them
-
implement a whole changeset for spk index (@ValuedMammal)
-
make it optional since its not strictly needed for checking balance or listing utxos.
Some context from the call
The problem is with the KeychainTxOutIndex. @evanlinjin
