datomic use cassandra, peer got this error

java.lang.IllegalStateException: Attempting to call unbound fn: #'datomic.kv-cassandra/kv-cassandra

@isaac you need to add a dependency to you project to use cassandra

see http://docs.datomic.com/storage.html#sec-7

your mean this?

yes

Clearly, It is a java lib. Has no Clojure functions

The error told me — can not find a Clojure function, and actually I added this dependencies already.

The error you got indicates the datomic.kv-cassandra ns could not be loaded

probably because something related to cassandra is missing, but if you added the dep. already it should be able to load. Are you using the correct version?

No, chrisblom. I check the lib again. As I said before. this is an pure java lib, there is no possible contains Clojure functions

But I create this function myself. It’s worked

Yes i know, but i'm guessing that datomic.kv-cassandra depends on the lib. being present and the right version. So if something is wrong, datomic.kv-cassandra cannot be loaded, and hence you get the Attempting to call unbound fn: #'datomic.kv-cassandra/kv-cassandra error

@isaac what version of Datomic are you using? what does your datomic depedency declaration look like?

chirsblom, thanks for you hint. this function defined at datomic peer lib.

I just need require the namespace

@marshall I use the version of 0.9.5561

Datomic Pro?

yes

i would expect that error if you were using datomic-free peer depedency

free not support Cassandra

correct

Adding com.amazonaws/aws-java-sdk-dynamodb to our project causes a lot of aws log messages to end up in our logback output, does anyone know how to exclude this?

@jfntn Edit your logback configuration file, logback.xml to set a different level on the <logger> for the prefix of the AWS library.
