Redis Enterprise v6.4 or greater for the cluster.

For production, 250MB RAM with one primary and one replica is recommended, but for the quickstart or for development, 125MB and a single shard is sufficient.

If you are deploying RDI for a production environment then secure this database with a password and TLS.

Set the database's eviction policy to noeviction. Note that you can't set this using rladmin, so you must either do it using the admin UI or with the following REST API command:

curl -v -k -d '{"eviction_policy": "noeviction"}' \
  -u '<USERNAME>:<PASSWORD>' \
  -H "Content-Type: application/json" \
  -X PUT https://<CLUSTER_FQDN>:9443/v1/bdbs/<BDB_UID>

Set the database's data persistence to AOF - fsync every 1 sec. Note that you can't set this using rladmin, so you must either do it using the admin UI or with the following REST API commands:

curl -v -k -d '{"data_persistence":"aof"}' \
  -u '<USERNAME>:<PASSWORD>' \
  -H "Content-Type: application/json" 
  -X PUT https://<CLUSTER_FQDN>:9443/v1/bdbs/<BDB_UID>
curl -v -k -d '{"aof_policy":"appendfsync-every-sec"}' \
  -u '<USERNAME>:<PASSWORD>' \
  -H "Content-Type: application/json" \
  -X PUT https://<CLUSTER_FQDN>:9443/v1/bdbs/<BDB_UID>

Ensure that the RDI database is not clustered. RDI will not work correctly if the RDI database is clustered, but it is OK for the target database to be clustered.
