Under the hood, Lucene can support this by keeping multiple commit points in the index.
So you'd make a new commit whenever you finish indexing the updates from each hour, and record that this is the last "searchable" commit. Then you are free to commit while indexing the next hour's worth of changes, but these commits are not marked as searchable. But... this is a low level Lucene capability and I don't know of any plans for Solr to support multiple commit points in the index.
