I have a couple dynamoDb questions, does anyone have a favorite place to ask those online? Stack overflow?

Here if datomic related @drewverlee , #aws otherwise

I'll answer either place :)

The doc lists CloudWatch metrics to be monitored. https://docs.datomic.com/cloud/operation/monitoring.html#metrics but I cannot find HttpDirectThrottled and HttpEndpointThrottled metrics on my CW. Are those metrics still available? or am I missing something?

popoppo07:12:18

our version is 781-9041

jaret13:12:24

The metrics are reported in Cloudwatch when triggered (i.e.this indicates you haven't been throttled), but you should probably see HTTPDirectOpsPending, but if you haven't triggered throttled it won't report. https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/viewing_metrics_with_cloudwatch.html: > "Metrics that have not had any new data points in the past two weeks do not appear in the console."

@U1QJACBUM got it. Thanks!!

We got a nvd warning this morning regarding a dep on Datomic (1.0.6202) > pkg:maven/com.h2database/[email protected] - CVE-2021-23463 Is this a false positive, a known issue or something that we can safely ignore?

jaret12:12:07

Hi @U9M6WJ9PV h2 database is used for dev protocol DBs. I will double check with the dev team and loop back here. Generally, I also recommend that you upgrade to the latest 1.0.6344 when you are able.

Twan13:12:49

Because of https://clojurians.slack.com/archives/C03RZMDSH/p1633091502190900 we are not able to move to 1.0.6344 yet. Talking about that, is there any ETA on a fix for that issue?

Twan13:12:42

Thanks for checking out on the h2 story 🙂

jaret13:12:08

Yeah there should be a fix in our next release for the issue you referenced, but you can also work around it by only downgrading the peer-server if you do upgrade your transactor and peer.

jaret13:12:20

And to be clear, we are looking at addressing the vulnerability you reported as well. However, development is investigating how to approach.

jaret19:12:44

@U9M6WJ9PV initial investigation indicates that this CVE is not exposed by Datomic's usage. None-the-less we will be updating our version of H2 in an upcoming release.

Twan19:12:40

Cool, thanks! That's good to know

anders17:12:59

Anyone from Datomic support here? We have issues with transactor (on prem) failing to start due to invalid license that we just took delivery of (`Terminating process - License not valid for this release of Datomic`)

jaret19:12:30

Hi Anders! I just e-mailed you a temporary license that will work. We have identified the issue with your license creation and will need to deploy new code to my.datomic to address the problem. Apologies for the inconvenience this may cause and thank you so much for reporting this issue!

Alex Miller (Clojure team)17:12:01

prob best to file a ticket https://www.datomic.com/support.html

anders17:12:57

thanks, will do

Can I configure an Ions instance to be available only on a private amazon subnet? I’m sorry, I’m bad at AWS. Just a general direction reference would be nice, thanks!

jaret19:12:04

https://docs.datomic.com/cloud/operation/vpc-access.html. The created VPC for Datomic and the created subnets are private and can be used for Ions.

jaret19:12:34

Depends on what you are after specifically, but that doc is probably a good place to start.

Ivan Fedorov20:12:35

Thanks @U1QJACBUM! Thats helpful! I’m looking to deploy a frontend-server EC2 node inside Datomic’s VPC and make it open to the web, but keep the backend only accessible from the VPC
