Data teams should be modelling companies similar to how @paulkrugman modelled the economy

What is an Operational model? #coalesceConf Image
Now citing @josh_wills (with his impressive hat) and examples of operational models that he's discussed ImageImage
Operational model for facebook. It's decomposable and each metric can have an entire team dedicated to it
#coalesceConf Image
Same for Slack and Snowflake #coalesceConf ImageImage
You can have secondary models that relate to the main one, driving individual metrics #coalesceConf ImageImage
Now citing @g_xing and operational models at Lyft. Low-margin business, how do you make decisions?

Is this the same thing that finance teams do in Excel? Basically… yes 😆 #coalesceConf Image
This is the holy grail of what we should be doing, working on models that describe how the business works. It's a team effort, it cannot be done by the data team on their own. #coalesceConf Image
What are the best metrics for… whatever…
This is putting the cart before the horse. Don't chase the metrics of other businesses. #coalesceConf Image
Decide the metrics based on how the business works, don't build the business around the metrics. To do so would be inflicting more than a mere flesh wound… #coalesceConf Image
Listening to @bennstancil is enlighting, entertaining, educational…and a wee bit exhausting 😅
I love how much work goes into his talks, with the delivery and slides meshing perfectly. A+++ would definitely listen again. @coalesceconf #dbtCoalesce kickof
@bennstancil @coalesceconf Benn's slides with useful speaker notes are online here: docs.google.com/presentation/d…

Gosh, I'd forgotten the pleasures and pains of abstract review for a conference. Pet peeves this morning:

☠️ Vendors submitting piss-poor product pitch abstracts. It doesn't take a genius to see through your abstract and look you up on LinkedIn to put 2 and 2 together. (1/n)
If you're a vendor, be open about your talk and its content. Pitching per se is not evil, but trying to hide it is. If you have useful things to say then perhaps your talk will be useful for the confernce. But be up front and honest about it. (2/n)
☠️ DAs with piss-poor abstracts. This is *literally your job*. Either bring it, or GTFO.
There are so many resources out there to help with writing abstracts (and hey, DM me and *I'll* help too, srsly), but you cannot just phone it in. It looks bad on you, and your company (3/n)

.@bennstancil's talk at @coalesceConf is starting!
@bennstancil @coalesceconf It's hard to measure the success of a data team #coalesceConf
that can be fine when the economy is fine, but as things get tough you end up with tough questions #coalesceConf

So does @MySQL Heatwave "Lakehouse" actually act as a lakehouse as defined elsewhere and write *back* to object storage through a table format? Or it's just MySQL that can also query data that's on object storage? The latter is cool of course, but the naming is puzzling me.
The press release is unclear, other than in the fact that OMG OUR BENCHMARK SHOWED WE ARE FASTER, WHO'DA THUNK IT?!! oracle.com/news/announcem…
The technical brief (oracle.com/a/ocom/docs/my…) makes note of "the HeatWave internal format" for working with external data. There's lots of mention of CSV and Parquet and magic fairies^H^H^H^H^H^H^Hmachine learning to guess at schemas.

Audience feedback at conference talks is *really* useful for speakers and organisers. It lets speakers understand what they're doing well (and perhaps what they're not). It helps organisers gauge the direction of content (more of this, less of that).
Reading these this morning makes me very proud of all the speakers at #Current22 😁
There's also some fair criticism in there that's great feedback to work with speakers and the program committee on

Looks like a fascinating set of talks at @coalesceconf #dbtcoalesce next week. I'll be firing up my 56k modem and dialling in for several of them including:
Keynote: The End of the Road for The Modern Data Stack You Know, from @jthandy and @margaretfrancis

coalesce.getdbt.com/agenda/keynote…
Intentional learning: How and why you should learn Data Jawn, from @notamyfromdbt

I loved chatting to Amy at #Current22 and I also need to find out what a Jawn is :D

Can’t wait for this panel discussion at #current22 with ⁦@takidau⁩ ⁦@notamyfromdbt⁩ ⁦@krisajenkins⁩ ⁦@AdiPolak⁩ ⁦@esammer⁩ - it’s gonna be awesome!
(and it’s being live-streamed - make sure you tune in!) Image
Are we going to have batch and streaming forever, or will they converge? @esammer says at the heart of systems lambda arch will go away and kappa will eventually win out. Once in DW perhaps batch will remain for its familiarity to analytics engineers. Image
@notamyfromdbt - Microbatching gets used to simulate streaming but with same toolset for familiarity, but it doesn’t scale
