How to solve voter address not available in EventVote?

[ryanchristo]

Summary

In the current implementation, we index group votes. EventVote is emitted when a single voter has submitted their vote but the event only includes the proposal id. In order to then query the vote to index, we need to query all current votes by proposal id and then loop through the votes rather than querying the single vote by proposal id and voter address.

Possible Solutions

• The voter address could be added to EventVote enabling us to query a specific vote (historical events would not be updated so this would only solve future votes).
• We could extract the voter address from the transaction messages (this would solve historical events and future events but there is some complexity as to how we would do this to account for MsgVote being wrapped in other messages, i.e. gov and group proposal messages, authz authorization messages, and interchain transactions). See golang example here.
