Description

The Set-AzRedisCache cmdlet modifies an Azure Cache for Redis.

Examples

Example 1: Modify Azure Cache for Redis

Set-AzRedisCache -ResourceGroupName "MyGroup" -Name "MyCache" -RedisConfiguration @{"maxmemory-policy" = "allkeys-random"}

PrimaryKey         : ******
          SecondaryKey       : ******
          ResourceGroupName  : mygroup
          Id                 : /subscriptions/a559b6fd-3a84-40bb-a450-b0db5ed37dfe/resourceGroups/mygroup/providers/Microsoft.Cache/Redis/myCache
          Location           : North Central US
          Name               : MyCache
          Type               : Microsoft.Cache/Redis
          HostName           : mycache.redis.cache.windows.net
          Port               : 6379
          ProvisioningState  : creating
          SslPort            : 6380
          RedisConfiguration : {[maxmemory-policy, allkeys-random]}
          EnableNonSslPort   : False

          Tag                : {}
          Zone               : []

This command updates the maxmemory-policy for your Azure Cache fo Redis named MyCache.

Example 2: Modify Azure Cache for Redis - If you want to Disable RDB or AOF Data Persistence.

Set-AzRedisCache -Name "MyCache"  -RedisConfiguration @{"rdb-backup-enabled" = "false"}

PrimaryKey         : ******
          SecondaryKey       : ******
          ResourceGroupName  : MyGroup
          Id                 : /subscriptions/a559b6fd-3a84-40bb-a450-b0db5ed37dfe/resourceGroups/mygroup/providers/Microsoft.Cache/Redis/MyCache

          SslPort            : 6380
          RedisConfiguration : {[maxmemory-policy, allkeys-random], [maxclients, 7500], [maxmemory-reserved, 200],
                                [maxfragmentationmemory-reserved, 300], [rdb-backup-enabled, false]...} 
          EnableNonSslPort   : False
