Amazon ElastiCache Construct Library

This module is part of the AWS Cloud Development Kit project.

import elasticache "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::ElastiCache.

Functions

func CfnCacheCluster_CFN_RESOURCE_TYPE_NAME 

func CfnCacheCluster_CFN_RESOURCE_TYPE_NAME() *string

func CfnCacheCluster_IsCfnElement 

func CfnCacheCluster_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnCacheCluster_IsCfnResource 

func CfnCacheCluster_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnCacheCluster_IsConstruct 

func CfnCacheCluster_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func CfnGlobalReplicationGroup_CFN_RESOURCE_TYPE_NAME() *string

func CfnGlobalReplicationGroup_IsCfnElement

A CloudFormation `AWS::ElastiCache::ReplicationGroup`.

The `AWS::ElastiCache::ReplicationGroup` resource creates an Amazon ElastiCache Redis replication group. A Redis (cluster mode disabled) replication group is a collection of cache clusters, where one of the clusters is a primary read-write cluster and the others are read-only replicas.

A Redis (cluster mode enabled) cluster is comprised of from 1 to 90 shards (API/CLI: node groups). Each shard has a primary node and up to 5 read-only replica nodes. The configuration can range from 90 shards and 0 replicas to 15 shards and 5 replicas, which is the maximum number or replicas allowed.

The node or shard limit can be increased to a maximum of 500 per cluster if the Redis engine version is 5.0.6 or higher. For example, you can choose to configure a 500 node cluster that ranges between 83 shards (one primary and 5 replicas per shard) and 500 shards (single primary and no replicas). Make sure there are enough available IP addresses to accommodate the increase. Common pitfalls include the subnets in the subnet group have too small a CIDR range or the subnets are shared and heavily used by other clusters. For more information, see [Creating a Subnet Group](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SubnetGroups.Creating.html) . For versions below 5.0.6, the limit is 250 per cluster.

To request a limit increase, see [Amazon Service Limits](https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html) and choose the limit type *Nodes per cluster per instance type* .

A CloudFormation `AWS::ElastiCache::UserGroup`.

For Redis engine version 6.0 onwards: Creates a Redis user group. For more information, see [Using Role Based Access Control (RBAC)](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Clusters.RBAC.html)

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnUserGroup := awscdk.Aws_elasticache.NewCfnUserGroup(this, jsii.String("MyCfnUserGroup"), &cfnUserGroupProps{
	engine: jsii.String("engine"),
	userGroupId: jsii.String("userGroupId"),

	// the properties below are optional
	userIds: []*string{
		jsii.String("userIds"),
	},
})

func NewCfnUserGroup 

func NewCfnUserGroup(scope constructs.Construct, id *string, props *CfnUserGroupProps) CfnUserGroup

Create a new `AWS::ElastiCache::UserGroup`.

type CfnUserGroupProps 

type CfnUserGroupProps struct {
	// The current supported value is redis.
	Engine *string `field:"required" json:"engine" yaml:"engine"`
	// The ID of the user group.
	UserGroupId *string `field:"required" json:"userGroupId" yaml:"userGroupId"`
	// The list of user IDs that belong to the user group.
