Redis supports persistence and not acting as a cache (with a LRU key eviction policy).
I would like to be able to provision a Redis cluster that never drops data added to it.577 votes
Redis persistence is now supported in Azure Redis Cache. Please see this for more details
https://azure.microsoft.com/en-us/blog/azure-redis-cache-general-availability-of-premium-tier/ and https://azure.microsoft.com/en-us/documentation/articles/cache-how-to-premium-persistence/
It should be possible to set a smaller interval for Redis snapshots (or a manually triggered one) and to choose between AOF or RDB or both for the persistence method.264 votes
Redis persistence is now available in the RDB as well as the AOF models. You can try out the AOF model today. AOF persistence is currently available as a Preview feature.
Here (https://docs.microsoft.com/en-us/azure/redis-cache/cache-how-to-premium-persistence#configure-aof-persistence) is some documentation about how to configure AOF persistence.
In the portal today I can't scale up a Redis cache instanse. I'm stuck in Standard 250 MB and I want 1 GB. Does not seem to be possible.
My workaround now is to create a new redis cache with 1GB.237 votes
Not available cache service in Japan Region big opportunity loss. I no longer forced to use the East Asia bad latency.155 votes
We now support Japan West and Japan East regions. Happy caching !
I wanted to test the Redis Cache Failover scenario (with Standard edition) for an enterprise application. But with current portal there are no ways we can test this capability.
Also would also like to test scenarios when one of the cache server is not performing well what are the heuristic defined for failing over to other node.115 votes
reboot has been on all tiers for a while now
Allow me to have Redis Caches in different regions and link them together in a bi-directional sync configuration so when you add something to the cache in one region, the data gets replicated to the other caches. This keeps the cache local and fast when you're running a site in multiple regions.86 votes
Geo-Replication is now available for use as a feature. It is released as a Preview at the moment. The replication is uni-directional at the moment.
Geo-replication provides a mechanism for linking two Premium tier Azure Redis Cache instances. One cache is designated as the primary linked cache, and the other as the secondary linked cache. The secondary linked cache becomes read-only, and data written to the primary cache is replicated to the secondary linked cache. This functionality can be used to replicate a cache across Azure regions.
Here is some more information: https://docs.microsoft.com/en-us/azure/redis-cache/cache-how-to-geo-replication.
We will continue to add more geo-replication scenarios. Please let us know what you’d like to see and in what priority order.
Receiving a callback when a key expires is currently not supported. Please add this as it provided a great way for handling session expiration.82 votes
Add support for using a hyphen in the URL for a redis cache instance. myapp-dev or myapp-test is much more aesthetically pleasing and easier to parse than myappdev or myapptest.65 votes
This fix has been rolled out. You can now specify a name with a hyphen
Currently I havn't seen any UI command to Restart Azure Redis Cache Service.
I know there is a way to shutdown and start however missing in the portal.59 votes
This is available now.
Right now we have integration between classic virtual networks and Redis Cache.
It's a very strong blocker for migration from classic to v2 model and also blocker if customer already using v2 infrastructure...37 votes
We are pleased to announce that this has now been enabled. Please see this service announcement for more details https://azure.microsoft.com/en-us/updates/azure-redis-cache-premium-tier-support-for-azure-virtual-network-v2-arm-based-virtual-networks/
it would be great if we could further secure our Redis instance by defining the allowed IP addresses. Typically our cache is only accessed by our IIS application server therefore there is no need for the cache to be exposed to the public internet.37 votes
There are various things you can do now. You can deploy your cache into a VNET and have NSG rules restrict the traffic to what is desired. Please ensure to look at this so that you enable access to the required ports (https://docs.microsoft.com/en-us/azure/redis-cache/cache-how-to-premium-vnet#what-are-some-common-misconfiguration-issues-with-azure-redis-cache-and-vnets).
You can also use the firewall feature to configure firewall rules to restrict access to only certain IP addresses. You might find this (https://docs.microsoft.com/en-us/azure/redis-cache/cache-configure#firewall) useful.
Currently the Azure Redis Cache only allows the firewall to be set on premium pricing tiers. This security service should be available on all pricing tiers with a dedicated service30 votes
This is now available on all pricing tiers.
We can't configure "retention" for Azure Redis Cache Diagnostics right now, even though we were used to configure it from Preview Portal. Please re-enable "retention" setting so that we don't need to delete logs manually.
Redis Cache の診断ログにおいて、以前はプレビューポータルからリテンションを設定することができましたが、現在は設定することができません。利用者が手動でログを削除する必要がないようにリテンションの設定を有効化してください。27 votes
Add basic management features to see the content of the Redis cache (e.g. key items, values for keys, flush db etc.)22 votes
We have added Keys counter which allows you to see the total/ expired and evicted keys as well.
Since commands such as 'SAVE' and 'BGSAVE' are disabled on the azure redis,I was hoping to find a equivalent of this operation(save,bgsave) to take a snapshot of my data on the cache and download it for local testing or upload it a new azure cache with better plan/config since I cannot upgrade my current plan.17 votes
Import/Export is an Azure Redis Cache data management operation which allows you to import data into Azure Redis Cache or export data from Azure Redis Cache by importing and exporting a Redis Cache Database (RDB) snapshot. Please see this for more details https://azure.microsoft.com/en-us/documentation/articles/cache-how-to-import-export-data/
Why can we only reboot premium tier instances? I get that if we're on a multi-tenant setup we can't reboot - but once we get to STANDARD tier we should be able to reboot, not just premium.12 votes
Reboot is now supported on all tiers. Documentation can be found here: https://docs.microsoft.com/en-us/azure/redis-cache/cache-administration
Allow import of block blob data to redis , as of now my .rdb file should be multiple of 512 bytes for page blob
I am not able to upload my .rdb file as page blob to azure storage , as the file size is not in multiple of 512 bytes
The back up I took from other cloud provider7 votes
This has been fixed for some time now.
Maintenance time of RedisCache server should be out of business hours in Japan
The last maintenance started 0:00 UTC. That hit business start time in Japan (a.m. 09:00 JPT). The business impact was critical.
Please plan the maintenance in Japan out of business hour in Japan considering local time.7 votes
You might find the scheduled patching feature useful.
It would be really useful if Azure Government supported Azure Redis Cache.3 votes
Azure Redis Cache is available in Azure Government. Please see this page for more information on the regions Azure Redis Cache is available in . https://azure.microsoft.com/en-us/regions/#services
It would be good to be able to programmatically create and manage Azure Redis Caches. Example scenario: bringing up an automated test environment for a short time to test builds/applications before deployment to production space without interfering with production cache.3 votes
Azure Powershell now has full support for Azure Redis Cache
- Don't see your idea?
