morning!

Although we Aquarians don’t believe in astrology, my chart for this week said I would say hello to a stranger

Morning

Morning

What day is it?

one that is ruled by Jupiter

Well I have a 14.28% chance of getting it….. 🙂

Even after looking at my calendar.

@raymcdermott further north that day is ruled by Thor

🍿

why can't these thunder gods all just get along?

Meanwhile at the other side of the pond: Cognitect joins Nubank. Huh?

sounds like good money for Cognitect and I'm guessing that NuBank are making sure that they still get the support for Datomic they need

Maybe JUXT should now join <random other fintech company in the South of Europe> just for the symmetry.

I'd sort of presumed that was the way it was going to go for juxt (or some other big investment from a consortium of banks as I think that crux is at more than one and they don't like paying their competitors to use tech, but will join together to do it)

so this will make Clojure (and Datomic) more sustainable (financially) in the long run...?

should do ... I can only assume that nubank have much better financial engineering skills than cognitect

also, no more consulting from Cognitect

but still do Datomic support

Let's hope for Datomic open source 🙂

Yeah, i think having a big corporate sponsor like a bank, with deep pockets, is ultimately a good thing. but i wouldn't hate if it remained truly independent (although, who can say what it really means to be independent?)

Maybe buying Cognitect was cheaper than buying more Datomic licenses 😉

2300 datomic databases at 5k per databases is a lot haha

why so many DB's? because of microservices?

we should ask them? maybe they hit the 1B datoms

quite fast

afterwards they might not have as much transactors

they shard heavily I think.

which makes sense for a bank (at least some parts of it)

why?

shard by account I presume?

I imagine group of accounts yes

you get better perfs all around, less data to carry around, easier maintenance (backups/restore & co) etc etc

there are quite a lot of advantages to do that. then you loose cross db queries I think (I am not super familiar with datomic)

makes sense I guess

Clojure question though.... anyone here gone Serverless with OpenWhisk?

you can probably do your controlling function queries separately. I'd do that in a relational database. Don't do analysis on the same DB you do transactions

you might even want to just store it in S3 and do something like aurora or other straight to s3 storage things

you can have as many dbs as you like though? pay per transactor instance?

yes, that's correct the license is by transactor not dbs

I wonder what is the maximum load of a transactor.

I think you can get that from http://datomic.com

good morning! Is there an idiomatic way in clojure to manage authorization in web applications? or is this typically done using middlewares?
