How many Redis databases can I create and manage?

The number of databases is unlimited. The limiting factor is the available memory in the cluster, and the number of shards in the subscription (for additional details, refer to What do you mean by the term Shard?).

Note the impact of the specific database configuration on the number of shards it consumes. For example:

  • Enabling database replication, without enabling database clustering, creates two shards: a master shard and a slave shard.
  • Enabling database clustering creates as many database shards as you configure.
  • Enabling both database replication and database clustering creates double the number of database shards you configure.
