"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"
Reflections by @Intellyx's Eric Newcomer [1/2]
🎁 XTDB 2.1 is now released 🎁 Thanks to the decoupled, shared storage architecture you can now dynamically ATTACH secondary databases with full read-write abilities and run queries across your Data Mesh with ease: xtdb.com/blog/attach-databas…

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...

We're running a series of XTDB v2 pre-launch events (informal chats on our Discord server) over the next few weeks. Later today we're speaking with @narayanarjun about as-of joins and database architecture - come join!
ALT Tedd Codd gifted us with the Relational Model, and many unsolved problems.

In the build up to an official XTDB v2 release we are running a series of informal chats on our Discord server - come join!
This Friday we're speaking with @narayanarjun who has battled many times with as-of chaos during his time at Materialize - see github.com/orgs/xtdb/discuss…
"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."

Here’s one I used last year. The representation is called Datalog. I used it with the XTDB database.

v2.0.0-beta6 is out today 🚀 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?"
