Step 3 - Deploy a Memcached memory-caching service

A Memcached memory-caching service will be used to cache the id of events that are received from SAP Customer Data Cloud to eliminate duplicates and to ensure that events aren't processed more than once.

Note: "Since events may be sent more than once, use the id to check for duplicates. The id for a specific event will always be the same." — Source: SAP Customer Data Cloud documentation for Webhooks

  1. Create a namespace with the name cdc.

    kubectl create namespace cdc

  2. Add the Bitnami chart repository.

    helm repo add bitnami https://charts.bitnami.com/bitnami

  3. Download and install bitnami/memcached in the cdc namespace. This command will create a Kubernetes deployment as well as a service with the name bm-memcached.

    helm install bm bitnami/memcached --namespace cdc
