For the lazy: on the Democratic side, Talarico is leading Crockett by almost 8 points with 80% of the vote counted, while there is going to be a runoff between Cornyn and Paxton for the GOP, with Cornyn having a small lead at this stage.
An interesting piece of information is that there were about 77000 more votes cast for Democrats than Republicans, about 3%. That doesn't mean much, but it's an interesting signal.
