Error when trying to configure the Azure Cosmos DB integrated cache

manisha 20

I am trying to provision Azure Cosmos DB integrated cache in North Europe region for my cosmos db account which is already there. But I get the following error. I don't have zone redundancy enabled.

The requested region 'North Europe' does not support AZ provisioning yet. Please try other regions or disable zone redundancy for this region. Can somebody kindly help? Thanks

This is not required to have redundancy enabled to provision cache

@manisha
Thank you for reaching out. This is not expected. If account does not have AZ enabled, integrated cache provisioning is expected to succeed. Could you please share the database account name, timestamp of the error, and full error string (that includes the correlation GUID) so we can troubleshoot the issue. Please do not share it here on forum. Send an email to azcommunity@microsoft.com with the above details. Please mention in the subject Line: ATTN: Oury so I don't miss it. Regards, Oury

@manisha

The account you provided has availability zone enabled in North Europe.

There is limited AZ capacity and dedicated gateway is not available with availability zones.

We recommend you test the dedicated gateway in preprod for an account without availability zones first to verify it is a good fit for your workload.

Also let us know if AZ is a blocker for your workload and the regions that you are interested in.

Regards,

Oury

hi @Oury Ba-MSFT , Sorry, I was expecting a reply on the email and didn't check here.
I tried the dedicated gateway without AZ in north europe and it worked fine. But we wanted to keep AZ to make our services highly available. We didn't want to use zone redundancy as it will cost us more. Is there another region that supports both AZ and dedicated Gateway?

The Azure Cosmos DB integrated cache can support availability zones (AZ) in the same regions as Azure Cosmos DB. According to the documentation, availability zones are currently supported in the following regions:

Central US

East US 2

West US 2

West Europe

North Europe

Southeast Asia

Japan East

Australia East

UK South

Canada Central

You can enable zone redundancy by selecting one or more regions that support availability zones. As an example, West Europe could be.

Hi @Sergii Bielskyi , Thanks for your reply. But I am not sure if I understand it correctly. Can you explain what is the link between Azure Cosmos DB integrated cache and availability zones please? and why do I need to enable zone redundancy?

Hey, sure. This is not required to have redundancy enabled to provision cache. But you mentioned that you have an error about using AZ. Well, could you explain what that is the configuration of your Cosmos DB?

resource "azurerm_cosmosdb_account" "db" { name = "tfex-cosmos-db-${random_integer.ri.result}" location = "northeurope" resource_group_name = azurerm_resource_group.rg.name offer_type = "Standard"

enable_automatic_failover = true consistency_policy { consistency_level = "BoundedStaleness" max_interval_in_seconds = 300 max_staleness_prefix = 100000 } geo_location { location = "northeurope" failover_priority = 1 }

}

Got it, I suppose that to activate enable_automatic_failover means you need to use AZ. If you do not need to use it, try to set false in parameter enable_automatic_failover

Yeah. the region specified for AZ is North Europe. so if integrated cache is supported in north europe, why is it erroring ..

Perhaps, because you selected enable_automatic_failover = true that is a reason that you need to select AZ one more region (e.g. West Europe) before the provision Azure Cosmos DB integrated cache. https://learn.microsoft.com/en-us/azure/cosmos-db/how-to-manage-database-account#addremove-regions-from-your-database-account
