What am I allowed to do with the free version?
You can use, experience and administer the full capabilities of Redise Pack (RP), but you may not deploy it in a production environment. In addition, the free version allows a maximum of four shards and is limited to thirty (30) days of use after initial installation on the first server in the cluster. After the thirty day trial, the cluster will shift to read only status. The free version does not provide the same support options as the paid version. Finally, no SLA is provided with the free version. To continue operation of the cluster with full capabilities, you must purchase a subscription cluster key from Redis Labs.
