Pagination for QueryValidatorDelegationsRequest

[danbryan]

Hello, I am a validator on Kujira, and due to a recent change, many people have over 100 delegations now. These are mostly small fractional numbers, but it appears to have passed a limit used by the cosmos-exporter.

# curl -s cosmos-exporter:9300/metrics/validator?address=kujiravaloper1dnmz4yzv73lr3lmauuaa0wpwn8zm8s20memec4 | grep -v "#" |gr
ep cosmos_validator_delegations | wc -l
100

I believe the default pagination limit is 100

It looks like you support pagination in a few staking types like
QueryValidatorsRequest - source

but not for others like
QueryValidatorDelegationsRequest

Any chance you can add pagination support here:

we also got the same issue, maybe someone can hep us to figure it out

cosmos-exporter version v0.2.2

We (Defiant Labs) are working on a fix for this...

BTW, I do not think QueryValidatorsRequest supports pagination either. To support pagination you need to use the NextKey field and make additional requests, which it doesn't do. For now I am going to fix QueryValidatorDelegationsRequest (which is what Dan wanted). If someone confirms that there's other broken pagination I can fix those as well.
