Request Syntax

response = client.modify_serverless_cache(
    ServerlessCacheName='string',
    Description='string',
    CacheUsageLimits={
        'DataStorage': {
            'Maximum': 123,
            'Unit': 'GB'
        },

            'Maximum': 123
        }
    },
    RemoveUserGroup=True|False,
    UserGroupId='string',
    SecurityGroupIds=[
        'string',
    ],
    SnapshotRetentionLimit=123,
    DailySnapshotTime='string'
)

Parameters:

ServerlessCacheName (string) –
[REQUIRED]

User-provided identifier for the serverless cache to be modified.
Description (string) – User provided description for the serverless cache. Default = NULL, i.e. the existing description is not removed/modified. The description has a maximum length of 255 characters.
CacheUsageLimits (dict) –
Modify the cache usage limit for the serverless cache.
- DataStorage (dict) –
  
  The maximum data storage limit in the cache, expressed in Gigabytes.
  - Maximum (integer) – [REQUIRED]
    
    The upper limit for data storage the cache is set to use.
  - Unit (string) – [REQUIRED]
    
    The unit that the storage is measured in, in GB.
- ECPUPerSecond (dict) –
  
  The configuration for the number of ElastiCache Processing Units (ECPU) the cache can consume per second.
  - Maximum (integer) – [REQUIRED]
    
    The configuration for the maximum number of ECPUs the cache can consume per second.
RemoveUserGroup (boolean) – The identifier of the UserGroup to be removed from association with the Redis serverless cache. Available for Redis only. Default is NULL.
UserGroupId (string) – The identifier of the UserGroup to be associated with the serverless cache. Available for Redis only. Default is NULL - the existing UserGroup is not removed.
SecurityGroupIds (list) –
The new list of VPC security groups to be associated with the serverless cache. Populating this list means the current VPC security groups will be removed. This security group is used to authorize traffic access for the VPC end-point (private-link). Default = NULL - the existing list of VPC security groups is not removed.
- (string) –
SnapshotRetentionLimit (integer) – The number of days for which Elasticache retains automatic snapshots before deleting them. Available for Redis only. Default = NULL, i.e. the existing snapshot-retention-limit will not be removed or modified. The maximum value allowed is 35 days.
DailySnapshotTime (string) – The daily time during which Elasticache begins taking a daily snapshot of the serverless cache. Available for Redis only. The default is NULL, i.e. the existing snapshot time configured for the cluster is not removed.

Return type:

dict
