Cache

Azure Cache is a family of cache offerings that support high throughput, low-latency data access, to enable building fast, scalable applications.
- Azure Redis Cache (Preview) is based on the popular open source Redis Cache engine. The service gives users access to a secure, dedicated Redis Cache, managed by Microsoft.
- Azure Managed Cache Service: Built on App Fabric Cache. This is a dedicated managed service.
- In-Role Cache: Built on App Fabric Cache. This is a self-hosted cache, available via the Azure SDK.

  1. Work on creation time of Redis Cache

    The time of creating a Redis Cache is to long. It should be improved

  2. Smaller Premium Redis Instances

    I have a requirement, where need high network performance and enhanced security but only 50MB and 250MB or 1GB size, 6GB cache and paying £205/mo doesn't fit well our current total spend is £450/mo

  3. scale to basic

    Give an option to rescale back to Basic tier. I started with Basic, switched to Standard but soon realized that I can not utilize it in near future and wanted to roll back to Basic. I was surprised when I saw that this option was not available.

  5. Having Smaller Instance of Redis

    The smallest instance right now is 250 megs. I think you should have a tiny instance too of around 50 megs. The price for 250 megs can be high if you start a new application that require some caching but just for few megs.

  6. Provide Redis node event logs

    Currently if a Redis node swaps due to patching or failing there is no way to figure this out in the Azure portal. The only way to find out is to log a service ticket. Which isnt great for the customer and worse for MS.

    Please provide an event log in the portal that customers can use to see what node failures or swaps happen in the cluster.

  7. Service Status for Maintenance on hosts or Redis Service

    When maintenance is carried out on the Redis Cache hosts or Redis Services, no indication of this is given anywhere.
    We need to be forewarned about maintenance.
    When monitoring starts detecting issues we are then ready for it or at least know why we are getting the connection errors or timeouts.

    Currently when maintenance is done:
    Azure service status => ZERO INDICATION
    Azure Planned maintenance => ZERO INDICATION
    Health Alerts => ZERO INDICATION
    Redis Cache Health => ZERO INIDCATION

  8. Allow to specify TCP idle timeouts and enable TCP resets in internal load balancer of Redis Cache

    We use Jedis to connect with our Redis Cache. It has a known issue, which causes it to block indefinitely if a TCP connection fails during some operations. It happens due to infinite socket timeout specified for these operations. Link: https://github.com/xetorthio/jedis/issues/426

    We bumped into this issue recently during Redis Cache failover, when we experienced a significant number of socket timeouts. It looked like connections were not closed properly.
    One of the failed connections happened to be used for complex operation mentioned in above GitHub issue. As a result, our Jedis thread was blocked for 15 minutes before idle connection was…

  9. Azure Portal: Redis 'Sets' metric should include counts from cmdstat_hset, cmdstat_hmset

    According to documentation Redis 'Sets' metric should include stats from following commands: cmdstatset, cmdstathset, cmdstathmset, cmdstathsetnx, cmdstatlset, cmdstatmset, cmdstatmsetnx, cmdstatsetbit, cmdstatsetex, cmdstatsetrange, and cmdstat_setnx.

    Stats for hset and hmset commands are never displayed on 'Gets\Sets' chart in Azure portal. I've checked Redis stats using "info commandstats" command and those two stats (cmdstathset, cmdstathmset) are getting updated inside Redis Server but those changes are never reflected in Azure Portal metrics.
    Seems to be a bug.
    Related documentation: https://docs.microsoft.com/en-us/azure/redis-cache/cache-how-to-monitor

  10. Support RedisCache in Azure Stack

    Please add support of RedisCache in Azure Stack

    Azure RedisCache is a fundamental backbone service for applications using autoscaling (e.g: Cloud Service Web and Worker Role).

  11. Add measurable unit of Redis Cache performance like DTU (for SQL Database)

    We sometimes face performance issues. Microsoft provides the following documentation to investigate timeout problem.
    <https://azure.microsoft.com/en-us/documentation/articles/cache-how-to-troubleshoot/#stackexchangeredis-timeout-exceptions>

    But we can't identify root cause easily. So personally I think measurable unit of Redis Cache Performance like DTU for SQL database is very useful for customer. I understand Redis Cache Advisor is very helpful for us. But if you can, could you please consider this kind of ability for good experience.

  12. Support Redis 6.0

    Redis 6.0 is released and brings a highly desired feature such as access control.

    Are there plans to support Redis 6.0?

  13. Add ability to add modules to Redis Cache service

    It would be good to have the ability to add external modules to Redis Cache service. We have an use case to store JSON in Redis and ReJSON module supports that. Inability to add ReJSON to Azure Redis Cache costs us a lot.

  14. application insights redis cache dependency tracking

    hi, in one of my api i started calling redis cache using microsoft redis client library for .net core. so it will check in cache and if not found then it will call another microservice using httpclient call. Am noting in application insight end to end transaction details page its not showing up calls made to redis cache. I will have to use custom api to send that data to application insight it would be great if application insights even shows external calls to redis cache grouped in transaction details report in application insights

  15. Ability to view list of connected clients

    While on a support call you provided a list of the connected clients to a Redis Cache that we ourselves were not able to get through running commands, example below:


    Initial Analysis: For rediscache here is the connected clients:
    [04:32:23.4286188] Current Connections per Client (master):
    Connection Type: Normal
    104.45.143.245 (
    2000000) => 4299
    104.45.143.245 (
    2000002) => 546
    104.45.143.245 (
    2000001) => 96
    104.45.143.245 (
    2000004) => 12
    52.170.215.107 (
    ***000001) => 6


    To have the ability to get this list would be very helpful from a troubleshooting standpoint as today we are only able to get a list of…

  17. Redis Cache host server update

    We want to see the health report of Redis Cache if host server or guest server on which Redis cache is running is getting upgraded.

    Currently, we don't have any report about when the redis cache became unavailable. Yesterday our redis cache was failing to make connection to our application and it failed with Socket failure error when I looked into the resource health it was showing available so this information was not correct.

  18. [Request] Please fix error messages when deploying Azure Redis Cache

    I try to create Azure Cache for Redis on VNET that does not meet the inbound and outbound port requirements, I get the following error:
    {"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.","details":[{"code":"Conflict","message":"{\r\n &quot;status&quot;: &quot;Failed&quot;,\r\n &quot;error&quot;: {\r\n &quot;code&quot;: &quot;ResourceDeploymentFailure&quot;,\r\n &quot;message&quot;: &quot;The resource operation completed with terminal provisioning state 'Failed'.&quot;\r\n }\r\n}"}]}

    Since the error message was confusing, it was confused with the presence of Redis of the same name, and it took a long time to investigate.
    Could you please improve the error message properly when building of Azure Redis…

  19. Have better status report in portal

    It is extremely frustrating when the redis server keeps refuse connection and there is no indication of why it is so in the portal. Since the server seems to be sending ECONNRESET to all command, I can't use redis-cli to check or recover.

    Also once the redis cache reachs max connection, there is no way to manage either from redis-cli or portal

  20. Add more detailed analytics about gets and sets to diagnose problems and monitor cache

    Currently there's no easy way when we see a spike in gets or sets to see what's happening. We have to start guessing, and neither the monitoring dashlets nor the Application Insights external dependency track are useful. It'd be great to have some form of get/set tracking to diagnose problemas.
