#Uber redesigned its #MySQL fleet using a consensus-driven architecture based on MySQL Group Replication:
✅ Cluster failover dropped from minutes → seconds
✅ Leader election & failure detection now inside the database layer
✅ Improved availability, simpler orchestration, stronger consistency across thousands of production clusters

Starting with #MySQL 9.6, foreign key validation & cascade actions will be managed by the SQL layer instead of the InnoDB storage engine.

Why this matters ❓
✅ Better change tracking
✅ More accurate replication
✅ Stronger data consistency

This shift makes MySQL more reliable for CDC pipelines, mixed-database environments, and analytics workloads.

Better late than never, pt. 2: We have published the (very long) blog post summarising our research seminar in Oslo last April.
👉 Read it on our blog!
https://dsenetwork.hypotheses.org/146

A group of textual scholars & software engineers discussed challenges of #DigitalScholarlyEditions regarding #Sustainability, mainly from a Norwegian perspective.

Headlined by @helling_patrick, we looked at #Coptic #Manuscripts, #Runes in #RelationalDatabases & #XML, #Mycenean #Inscriptions & #Norwegian #ArchivalEditions

Congrats to @codydunne & Wolfgang Gatterbauer for their #SIGMOD 2024 best paper honorable mention (one of 3 for the conference)!

Trying to come up with the fundamental principles of the #RelationalDatabases and #SQL way of thinking:

- Common Language
SQL as the "lingua franca" of data. This was revolutionary 50 years ago when data had a "tower of babel" situation.

- Single source of truth
To avoid ambiguities and to conserve (expensive lol) storage space.

- Garbage in = Garbage out
Use strong typing at input-time to ensure data quality at output-time.

What else might also be such a high-level guiding principle?

Managed #RelationalDatabases offer convenience, but are you aware of the hidden costs?

Gain valuable insights into monitoring service expenses, revising default settings, and understanding operational constraints.
