#xtdb

I was sick for the last ~ 10 days. Done almost nothing. Feeling kinda recovered today.

But had some shorts moments of clarity to play with #xtdb (#clojure) https://xtdb.com

I saw it ~ year ago when it was v1. Then they've released v2 with some breaking changes.

Summary: cool idea, but still raw as f.
The last drop for me was: they have an option to add metadata to the transaction but it's hidden from the public api and the PR is there for ~ 2 years

Biff: Batteries-Included Web Framework for #Clojure

At some point (I missed the memo) #xtdb stopped espousing #datalog and invented #xtql. I'm guessing this was to step out of any annoying dependencies of datalog and dampen comparison with the other major datalog approaches in #Clojure.

https://docs.xtdb.com/intro/what-is-xtql.html I especially enjoy the side-by-side Clojure/JSON comparisons here

#git must have been the first successful bitemporal database.

The commits trees are the domain time, and the reflog is the transactional time.

It must has been the inspiration to #datomic and #xtdb.

@aphyr Many thanks for this talk Kyle - lots of great pointers for our work on #XTDB

@fndriven Have you tried asking in the #xtdb slack channel?

Have you ever heard of a "bitemporal" database?

This week, I'm talking to James Henderson, lead developer of #XTDB, to explore the world of bitemporality and the life of a #database developer.

"State of XTDB" by Jon Pither
https://www.youtube.com/watch?v=gQV-XrkJj2o

Talk about the current and upcoming evolution of the #XTDB database. The coolest thing about this, to me, is the introduction of the new temporal features and how you're able to query over them. To people who've never used a temporal database before, time travel is mind blowing enough, but what's presented there takes it to a new level. Off the top of my head, I don't have a use case for it, but it sure is interesting.

A great #clojure discussion of #XTDB and others vs standard SQL. https://teddit.net/r/Clojure/comments/yj1oah/open_source_datomic/

Has anyone built a #clojure #xtdb activity pub thing yet?

An interesting read on vmware's SplinterDB, based on a conversation from #xtdb in Clojurians Slack:

You can try it out:

It's been a while since I saw the @xtdb @xtdb_com front page, but it's looking great now as I did my first bit of workplace evangelism for the #xtdb database https://xtdb.com/ . It has potential for university humanities research projects.
