"If I had a requirement to monitor all the new systems that we've onboarded, for their first three days, to ensure they stay within agreed limits, could we do that with @xtdb.com?"

Time-oriented requirements are *everywhere*!

[ANN] 2.0.0-beta6 · XTDB

@xtdb.com beta6 is out today 🚀

Containing the sorts of changes that don't make for very exciting release-notes, but all the little things you'll appreciate when you're actually working with it day-to-day/deploying it into production.

No buzzwords this time I'm afraid!

Anyone I know use Google Cloud? looking to set up a small k8s cluster with c4-family machines for a proof-of-concept and I'm getting the full 'you need to schedule a call with a sales rep' rigmarole... What'm I missing?

AWS it's either just part of the default quotas or it's a simple automated form

Based on the SQL-spec, why do we need to use locks at all (in an MVCC DB), when we do REPEATABLE READ or READ COMMITTED? Why can't we just expose changes at commit with a future timestamp and read with a past timestamp?

Is this like a "vestigial organ" thing?

Always good to cut a release - today, @xtdb.com 2.0.0-beta5 🚀

Introducing "template-friendly" SQL, for everyone who's ever battled with commas and ANDs in generated queries, as well as cutting down on subqueries in common cases

Oh, and faster ingest, that always helps ☺️

Definitely implemented this by hand myself too many times in the past before I joined the @xtdb.com team 😅

Diagram with large number: 2.7.123 First “2” is commented: Proud version. Bump when you are proud of the release Second “7” is commented: Default version. Just normal/okay releases Third “123” is commented: Shame version. Bump when fixing things too embarrassing to admit

I propose we replace semantic versioning with pride versioning

The missing SQL sub-queries · XTDB

Blogged: "The Missing SQL Sub-queries"

SQL's had sub-queries since SQL:92 - but it's still a challenge to return properly nested data through SQL queries.

#XTDB has first-class support for nested values, as well as `NEST_ONE` and `NEST_MANY`, which fill this gap:

How (and how not) to disagree with your manager Disagreements with your manager are inevitable, and it can be tempting to just tell yourself that you can’t fight the boss and give up. Don't.
