hey, I create datomic cloud bucket backups every day, and now I'm trying to restore the data from some point. If I stop datomic instances and just replace bucket's content, I still see the latest data, not only from the , for example, 3 days ago backup. Or to re-create Cloudformation stacks is the only way?
I'm 90% positive you will not be able to restore a datomic cloud instance from s3 backups alone. If you re-create the stack you will likely LOSE the information because you are not taking dynamodb into account with your s3 backups. Dynamodb contains the tx-log, which I'm pretty sure you don't get with the s3 bucket backups alone. Since you currently still have the dynamodb tx-log from today (not truncated to 3 days ago, and I'm not suggesting to truncate it), it makes sense that you are getting back information from today from dynamodb.
EFS also serves as an additional caching layer which might explain why you still see the latest data.
If you’ve had any failed deploys due to sync-libs failed to complete in 120 seconds
Please check out our latest ion-dev release where we have upped the timeout on sync-libs:

Hey Folks, is there a way to tell to datomic to inc a value in the database, based on whatever value it will found there?
Context: I just want to inc an attribute value in datomic, without have to inc
in application level. I want that to happen in datomic to avoid dealing with concurrence, cas
.
https://docs.datomic.com/cloud/transactions/transaction-functions.html#creating has that function as an example 🙂
