Clojurians Log v2

I am trying to set up a composite tuple index for lets say an account entity and I am doing this ( which is like something straight out of the docs )

{:db/ident       :account/company+number
 :db/valueType   :db.type/tuple
 :db/tupleAttrs  [:account/company :account/number]
 :db/cardinality :db.cardinality/one
 :db/unique      :db.unique/value
 }

I tryied to reproduce this issue here https://gist.github.com/souenzzo/3ba161909006ef08d53ac63a1d622fa2 But I can't understand where you are seeing this nil

@jeroen.dejong I was hoping to hear something like this. Can you share any more details? An example maybe?

Basically we created a 2 (internal) libraries. 1 for monitoring the tx-log, and updating those values into ES. The other exposes some search functions (uses spandex to perform a query). We put that library on the classpath of our peer server. Which allows the client to use the functions in our internal library to be used in datalog:

{:query '{:find [?e] 
          :where [(ourthing/search ?client ?search-term) [?e ...]]
          :in [$ ?client ?search-term]}
 :args [(d/db ...), {:hosts ["<http://127.0.0.1:9200>"]}, "Hello world!"]}

Most of this is very much WIP, but as far as I can tell right now it's a very viable solution.

Nice! Thanks for sharing this!

i am going to run this gist in my db and see if i can alter it to show good reproduction of issue

this does work on my db so that was interesting. thanks. i now have to correlate this with my schema and see what is different. Muchos thanks again!

Is anyone here using AssumeRole/STS to delegate access to sub-accounts in AWS, and successfully connecting to a running Datomic system with the Datomic CLI?

./datomic cloud list-systems --profile example-dev

I vaguely remember a problem with some Datomic tooling and use of assumed roles. The workaround was to juggle your AWS config about so you're not using profiles but this won't work here as I have to STS my way into the sub account. No direct access possible.

I've added the SSH ingress rule to the bastion security group, and I've attached the Datomic Admin policy to the role that gets assumed when you switch into the sub-account.

I don't know what the "log" is that the error refers to. I've seen that in cognitect-labs/aws-api too and didn't know what log was being referred to there either. 🙈

i found the problem .. we are doing this

{:db/ident       :accounting-category/company+number
                           :db/valueType   :db.type/tuple
                           :db/tupleAttrs  [:entity/company :accounting-category/number]
                           :db/cardinality :db.cardinality/one
                           :db/unique      :db.unique/value
                           }

and this attribute entity/company is shared with other entities.

seems like datomic trying to make this tuple for any entity with that attirbute and not just accounting-category entity

is there a way to stop that and only make this constraint tuple when this exact entity is created / edited ?

@joshkh this lib does exactly what you want but not yet for cloud https://github.com/vvvvalvalval/datomock/issues/6

thanks for sharing. i'm sticking to dev-local as being the "official" solution at the moment, and starting from a cloud db (whether remote or imported locally) is a must. no on-prem for me 🙂
