Feature Request

I would like to be able to use the data persistence offered by Premium tier Azure Redis Cache. However, this is not available via Terraform. I have included some relevant documentation from the Azure reference pages.

Hi @cberner

Thanks for opening this issue.

I've taken a quick look and unfortunately it's not available in the Azure SDK at present - so I've opened an issue on the Azure SDK for Go repository - so that we can support this in the future :)

Thanks! :)

👋 @cberner

Just to provide an update about this issue: I've heard back from the Azure Redis team - apparently it's possible to configure Redis Backups using keys in the redis_configuration section:

It is intended to be possible via the 'redisConfiguration' property of the redis cache:

See the note on https://docs.microsoft.com/en-us/rest/api/redis/redis

"Few possible keys: rdb-backup-enabled,rdb-storage-connection-string,rdb-backup-frequency,maxmemory-delta,maxmemory-policy,notify-keyspace-events,maxmemory-samples,slowlog-log-slower-than,slowlog-max-len,list-max-ziplist-entries,list-max-ziplist-value,hash-max-ziplist-entries,hash-max-ziplist-value,set-max-intset-entries,zset-max-ziplist-entries,zset-max-ziplist-value etc."

Currently, each field in the Redis Configuration is listed explicitly in Terraform - so this will need a code change in Terraform to support this, but it looks like this should be relatively quick to add :)

Thanks!
