LGTM as long as we paginate GetTotalSupply in a follow up

LGTM as long as we paginate GetTotalSupply in a follow up

Does it make sense to have seperate GetPaginatedTotalSupply as GetTotalSupply is being used across multiple places where the pagination is not necessary?

LGTM as long as we paginate GetTotalSupply in a follow up

Does it make sense to have seperate GetPaginatedTotalSupply as GetTotalSupply is being used across multiple places where the pagination is not necessary?

IMHO anywhere GetTotalSupply is being used without pagination should be viewed as a problem. What if there are 10,000 or 1 million denoms in state? That might seem crazy today but at least in our use case we'll be creating LOTS of micro-currencies.

alessio · 2021-03-03T09:28:58Z

I agree with @aaronc. Please at the very least let's open a follow-up issue.

alessio · 2021-03-03T09:29:31Z

@sahith-narahari please add a CHANGELOG entry too

Sure, I'll make a followup issue. Should we also extend the same to GetAllBalances which is more widely used across other modules without pagination

Yes, I think that makes sense too.

Is a state migration needed for this? If yes, could you add one in x/bank/legacy/042?

Sure, I'll do it in the followup PR along with paginating supply.

Yes it is. Could you add this to the tracking issue and reopen it @AmauryM ?

proto/cosmos/bank/v1beta1/bank.proto


-// Supply represents a struct that passively keeps track of the total supply
-// amounts in the network.
-message Supply {


This is a proto-breaking change. I'm okay to remove it in the v1beta2 package but not here.

I'm adding it back in the migration PR, and adding a deprecated comment to it.

We can keep it in the proto files even though it's not used for now. Deprecated is the right step.

Is there a reason this test was skipped?

@sahith-narahari

Oops sorry, this is unintended. Can you remove it in the store migration PR
