What Is a Partition?

Partitions are the base throughput unit of a DIS stream. When creating a DIS stream, you are expected to specify the number of partitions needed within your stream.

• Capacity of a common stream's partition: Each partition supports a maximum read speed of 2 MB/s and a maximum write speed of 1 MB/s or 1,000 records/s (the speed will be limited if either upper limit is reached). The total size of a request cannot exceed 1 MB (excluding the size of the partitionKey).
• Capacity of an advanced stream's partition: Each partition supports a maximum read speed of 10 MB/s and a maximum write speed of 5 MB/s or 2,000 records/s (the speed will be limited if either upper limit is reached). The total size of a request cannot exceed 5 MB (excluding the size of the partitionKey).

By default, each tenant has 1 to 50 partitions. Tenants can configure the number of partitions as required.

To increase the quota, submit a service ticket. The upper limit is calculated based on the actual load of the cluster.
