I've researched possible endless query execution when `HostSelectionPolicy` returns the same downed host ([CASSGO-50](https://issues.apache.org/jira/browse/CASSGO-50)) and propose three approaches to prevent it. - Wrap `hostIter` to prevent it from returning downed host before executing the query. e.g. ``` hostIter = func() SelectedHost { checkIter := hostIter() if !checkIter.Info().IsUp() { return nil } return checkIter } ``` But that approach can cause breaking changes. - Properly documented `type NextHost func()`: Add a comment for `NextHost` type describing that `NextHost` should return not downedhost or return nil - Add the threshold limit based on the number of hosts inside `(q *queryExecutor) do` which will prevent the endless execution without the breaking changes Implementations of the threshold and documentation are presented in this PR. -- This is an automated message from the Apache Git Service.
