Anyone here have experience with throwing analytical reporting loads at Datomic? (Basically what you'll tend to see in OLAP scenarios, with aggregations against large datasets for real-time reporting/drilldown etc)
I'm trying to find if Datomic would be a good fit for an api that would have to do aggregations of "facts" by hierarchical dimensions (stretching the terminology a bit here, I know it doesn't fit with Datomic's view of the world)
we use Onyx to watch the Datomic transaction report queue to produce stats and write them back to Datomic, @gurdas
Hi guys, is there anyway to build a project with datomic-pro with travis?
I tried to set and use the user credentials with travis http://docs.travis-ci.com/user/environment-variables/
and retrieving in lein with https://github.com/technomancy/leiningen/blob/master/doc/DEPLOY.md#credentials-in-the-environment
but still no way to get the build
thanks @taylor.sando for your reply I think these settings are not good for travis as far as I get the envs in my terminal working
tangrammers-MacBook-Pro:tamara tangrammer$ echo $datomic_user_name
tangrammers-MacBook-Pro:tamara tangrammer$ echo $datomic_pass
d81ba45d-...
but the error keeps the same when i start the repl
Caused by: org.sonatype.aether.transfer.ArtifactTransferException: Could not transfer artifact com.datomic:datomic-pro:pom:0.9.5327 from/to (): Not authorized , ReasonPhrase:Unauthorized.
at org.sonatype.aether.connector.wagon.WagonRepositoryConnector$4.wrap(WagonRepositoryConnector.java:951)
I don't know if it matters, but my actual environmental variables are all upper case DATOMIC_USER_NAME and DATOMIC_PASS
@taylor.sando: good point! it worked now
you saved my morning ! thanks a lot!
I think I remember having similar problems with lein environmental variables
(let [uri "datomic:]
(println "Deleted" uri (d/delete-database uri))
(d/create-database uri)
(println "Created" uri)
(let [conn (d/connect uri)]
(println "Connected to" uri)
(d/release conn)))
The first time I run this, it works. The second time, I get
Deleted datomic: true
Created datomic:
ExceptionInfo database does not exist clojure.core/ex-info (core.clj:4593)
I just want to start w/ an empty db 😐 Am I missing something?
There's nothing in the transactor log, either.
@pesterhazy: What version of Datomic are you using?
com.datomic/datomic-pro "0.9.5130"
@pesterhazy: From the 0.9.5327 release notes: * Bugfix: Fixed bug that prevented connecting from a peer that deletes and recreates a database name.
haha!
thanks!
sorry @pesterhazy, i should have warned you about that
