cluster_mode_enabledFlag to enable/disable creation of a native redis cluster. automatic_failover_enabled must be set to true. Only 1 cluster_mode block is allowedboolfalse
cluster_mode_num_node_groupsNumber of node groups (shards) for this Redis replication group. Changing this number will trigger an online resizing operation before other settings modificationsnumberfalse
cluster_mode_replicas_per_node_groupNumber of replica nodes in each node group. Valid values are 0 to 5. Changing this number will force a new resourcenumberfalse
cluster_sizeNumber of nodes in cluster. Ignored when cluster_mode_enabled == truenumberfalse
dns_subdomainThe subdomain to use for the CNAME record. If not provided then the CNAME record will use var.name.stringfalse
elasticache_subnet_group_nameSubnet group name for the ElastiCache instancestringfalse
engine_versionRedis engine versionstringfalse
familyRedis familystringfalse
final_snapshot_identifierThe name of your final node group (shard) snapshot. ElastiCache creates the snapshot from the primary node in the cluster. If omitted, no final snapshot will be made.stringfalse
instance_typeElastic cache instance typestringfalse
kms_key_idThe ARN of the key that you wish to use if encrypting at rest. If not supplied, uses service managed encryption. at_rest_encryption_enabled must be set to truestringfalse
maintenance_windowMaintenance windowstringfalse

snapshot_nameThe name of a snapshot from which to restore data into the new node group. Changing the snapshot_name forces a new resource.stringfalse
snapshot_retention_limitThe number of days for which ElastiCache will retain automatic cache cluster snapshots before deleting them.numberfalse
snapshot_windowThe daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster.stringfalse
subnetsSubnet IDslist(string)false
transit_encryption_enabledSet true to enable encryption in transit. Forced true if var.auth_token is set.\nIf this is enabled, use the following guide to access redis.\nboolfalse

writeConnectionSecretToRefThe secret which the cloud resource connection will be written towriteConnectionSecretToReffalse
zone_idRoute53 DNS Zone ID as list of string (0 or 1 items). If empty, no custom DNS name will be published.\nIf the list contains a single Zone ID, a custom DNS name will be pulished in that zone.\nCan also be a plain string, but that use is DEPRECATED because of Terraform issues.\nanyfalse
