@joshkh I believe there’s something in the “Understanding & Using Reified Transactions” presentation at https://docs.datomic.com/on-prem/videos.html - haven’t watched it for a while though, so it may only apply to on-prem (or I might be mixing up videos - but that’s a great one regardless).
@joshkh there’s a nice collection of db fns, which includes fns for reseting to-many rels: https://github.com/vvvvalvalval/datofu
Those use entity API, but are actually quite easy to rewrite with pull API (had to do this even on on-prem, cuz entity API introduced some subtle bugs for our case).
I don't think so unfortunately, but note that REBL might give you a lot of the same value prop.
i wrote a little personal-use webapp to interactively explore my data, and planned to release it after christmas along with a guide on deploying containerised datomic cloud apps on AWS. maybe you can help me test it? 🙂
it's a tree-like browser and (so far) supports transacting new values with in-place editing
Got this error when I was upgrading a Solo system from 535-8812
to the latest (https://s3.amazonaws.com/datomic-cloud-1/cft/569-8835/datomic-solo-compute-569-8835.json)
Export with name <datomic-system-name>-CodeBucketPolicyArn is already exported by stack <datomic-system-name>-Compute-1P5MYAP35641W
i have no idea what does it mean.
i just deleted a system in the same region earlier and kept the code bucket as documented on the https://docs.datomic.com/cloud/operation/deleting.html page.
i suspect it has something to do with this specific situation, because that stack deletion didn't go completely flawlessly.
it was not able to delete a security group because it couldn't delete the ENIs it was referring to, so i had to manually delete them.
for now i will just tear the stack down and try to pull up the latest one and reuse the existing storage.
at least i will exercise how to do this...Hello, i would like to ask if the client pro version should match the specific version of datomic downloaded on my machine. I heard so in a tutorial while i was using datomic-free. Now i have downloaded datomic starter version 0.9.5981 but it seems that the latest version of client pro offered by Maven is 0.9.41. I am getting an error while setting up a repl in intellij and I am not sure if that is the problem.

ERROR: AMQ214016: Failed to create netty connection
java.nio.channels.ClosedChannelException

Its working, seems like i had imported [datomic.api] instead of [datomic.client.api] for my case.
@shaun-mahood thanks for the video link, i'll check it out. and thanks to you too, @fjolne.yngling. transaction functions are the way forward.
