 Memory limits in Redis Cloud are subject to the same considerations as Redis Enterprise Software; to learn more, see [Database memory limits]({{< relref "/rs/databases/memory-performance/memory-limit.md" >}})
 
+### Throughput
+
+Throughput is the amount of operations a database can handle over a certain period of time. For most Redis Cloud databases, throughput is defined in operations per second (ops/sec).
+
+Databases with search and query enabled use the number of shards to determine throughput. To determine how many shards you need for your database, use the [sizing calculator](https://redis.com/modules/redis-search/redisearch-sizing-calculator/).
+
+Your actual throughput may not match the throughput you set when you create your database. The following things can affect your database's throughput:
+- **Command complexity**: O(N) and O(log(N)) commands will take more time than O(1) commands, and will affect throughput accordingly.
+- **Key and value sizing**: If your database's keys and values are very large, setting and reading those keys may take more time and affect throughput.
+- **Replication**: Using [multi-zone replication]({{<relref "rc/databases/configuration/high-availability">}}) affects throughput as each write operation is executed asynchronously in each zone.
