Currenty we are running Sitecore 9.0 on Azure Paas. I would like to know which is the purpose of the Azure Redis Cache?
Reading some documentation it seems that it´s to store session properties of users. We are an e-commerce site, but we are using a custom mechanism for the users session, not using the one provided by Sitecore. If we are not using it, is it necessary to have the Redis Cache?
We have looked at Redis, it contains a hundred of keys, with not readable content for us. In some blogs I read that the Redis Cache it´s useful decreasing response time in requests peaks. But I´m not sure if it´s useful when we are not using Session mechanism from Sitecore.
