[stellate] nftEntities - implement some kind of NullType

[yangwao]

To improve cache at Stellate

[vikiival]

Hello @yangwao, Can your colleague - guess @preschian give the parameters that were used?

Null entity

We can do custom resolvers, nftentites is a native query

where to improve

Currently our frontend is abusing indexer with bad queries

This one is mostly coming from Novawallet. ref: https://github.com/kodadot/ops-internal/issues/1460#issuecomment-2015283988

Also this one ?

That one is a different case. You can check on the "Insights" tab from the dashboard.

This compares all requests vs smartphones only on ahk one day.

all request	smartphone only

Please see how many "Passes" requests are different. Most of them come from Novawallet.

How to reproduce:

Return empty results always "PASS"

From the chat above, there are two workarounds.

1. Fix it on our side by implementing NullType
2. Fix it on the client side by extending the queries. Example:

[vikiival]

{ 
  "currentOwner_eq": ""
}

That should be never called :), Guess some composable is calling query like this

[preschian]

That should be never called :),

that one is only for example. You can change that with another address that doesn't have nft will get the same results
