"Handling the element of time in SQL has been a challenge since it was created"
"current databases require you to manually insert time values that track when a data item was added, when it became valid, and when it became invalid"

The theme of @CMUDB's ongoing Future Data Systems seminar series is "what should a database system look like in the future to handle more of our past so we never forget" - clearly I'm biased, but the answer has to be @xtdb_com ! Join us live on 24th November to learn more...

What if there was a Clojure library like re-frame, but all state was server-side in an @xtdb_com temporal DB?
What if the debugging tools took full advantage of this? SQL subs, SQL reactions, SQL debugging, SQL logs (clj, cljs, js) - all immutable with '1st class' time...

"It would be desirable to arrange the events so that a look into our data base will show the latest surface of the event space. At the same time it should be possible to penetrate beyond this surface along the lifelines into the past."

v2.0.0-beta6 is out today š Lots of bug fixing and resilience improvements in this one.
Next up is beta7, with improved support for time series data - we'll finally be able to settle an age old debate: "how is XTDB different to a time series database?"
