See tendermint/tendermint#3610 (comment)

Reasons to do that:

  • many KV stores does not support empty keys
  • I don't know why would someone want to set en empty key (and not call it default or something else)

Found this commit 4ce8448d7fcf92b040046f894474ce2f7e779b67, but it does not explain why nil keys are OK.

The SDK does not use empty keys. will see others then we can look at moving forward with this.

I'm making some breaking changes to the interface shortly, suggest we do this at the same time since there are a few issues with empty keys (notably BoltDB not supporting it, and cLevelDB panics). Any objections?

batch: return errors for all operations (#96)
442ebe1 
Modify batch `Set`, `Delete`, and `Close` to return errors. The main error condition currently is using closed batches, but future ones include databases which implement batches as transactions (e.g. BadgerDB) and rejecting empty keys (#2).
