• • You need to partition your data across two to 250 or 500 nodes if the Redis engine version is 5.0.6 or higher.(clustered mode only).
• • You need geospatial indexing (clustered mode or non-clustered mode).
• • You don’t need to support multiple databases.
• • Plus features of non-clustered mode

• • You need complex data types, such as strings, hashes, lists, sets, sorted sets, and bitmaps.
• • You need to sort or rank in-memory datasets.
• • You need persistence of your key store.
• • You need to replicate your data from the primary to one or more read replicas for read intensive applications.
• • You need automatic failover if your primary node fails.
• • You need pub/sub capabilities.
• • You need backup and restore capabilities.
• • You need to support multiple databases.

• • You need the simplest model possible.
• • You need to run large nodes with multiple cores or threads.
• • You need the ability to scale out and in, adding and removing nodes as demand on your system increases and decreases.
• • You need to cache objects, such as a database.
• • Needs Auto Discovery to simplify the way an application connects to a cluster.
