> Project: Solr
> Issue Type: Bug
> Reporter: Joel Bernstein
>
> Currently the TopicStream can miss documents if version numbers are received
> out-of-order. The TopicStream sorts on version number so it will only miss
> out-of-order versions that span commit boundaries.
> In order to resolve this issue we can adopt an approach that keeps a set of
> the last N version numbers sent for each Topic. As the documents are scanned
> we can check for documents within this time window that do not appear in the
> sent set. These documents can then be sent.
