Serverless Clusters
Serverless Clusters are currently in Public Preview. During this phase, we’re actively gathering feedback and refining the service. Features and availability may be subject to change. We encourage you to try it out and share your experiences with us.
Serverless clusters are the newest addition to StreamNative Cloud, offering a fully managed, auto-scaling solution with minimal operational overhead. Key features include:
- Instant provisioning with zero base cost.
- Automatic scaling based on your workload, with billing only for resources used.
- Simplified management with StreamNative handling all infrastructure concerns.
- Ideal for development, testing, and production workloads with variable traffic patterns.
StreamNative uses Elastic Throughput Units (ETUs) to provision and bill for the Serverless clusters.
ETU limits per Serverless cluster
Serverless clusters are elastic, shrinking and expanding automatically based on load. You don’t need to size your cluster. When you need more capacity, your Serverless cluster expands up to the fixed maximum. If you’re not using any capacity, you’re not paying for it.
Serverless cluster capacity
During the Public Preview period, the serverless cluster capacity limit is not enforced. This allows for greater flexibility in testing and usage. However, please be aware that these limits may be implemented in the future as the service moves towards general availability.
| Dimension | Minimum | Maximum |
|---|---|---|
| ETUs | 0 | 20 |
If consumption in a given hour is zero across all billable dimensions, you pay nothing. For more information, see Elastic Throughput Unit (ETU).
ETU capacity guidance
The dimensions in the following table describe the capacity of a single ETU. For more information about ETU, see Elastic Throughput Unit (ETU) and ETU vs CU/SU.
| Dimension | ETU Capacity |
|---|---|
| Ingress (Data In) | 5 megabytes per second (MBps) |
| Egress (Data Out) | 15 megabytes per second (MBps) |
| Data Entries | 500 entries per second |
Serverless limits per cluster
| Dimension | Capability | Additional details |
|---|---|---|
| Ingress (Data In) | Max 100 MBps | Number of bytes that can be produced to the cluster in one second. To reduce usage on this dimension, you can compress your messages. lz4 is recommended for compression. |
| Egress (Data Out) | Max 300 MBps | Number of bytes that can be consumed from the cluster in one second. To reduce usage on this dimension, you can compress your messages and ensure each consumer is only consuming from the topics it requires. lz4 is recommended for compression. |
| Data Entries | Max 10,000 per second | Number of data entries produced to and consumed from the cluster in one second. Each data entry represents a batch of messages. Both Pulsar and Kafka clients do batching at the client side. To reduce usage on this dimension, you can adjust producer batching configurations and shut down otherwise inactive clients. |
Serverless limits per partition
The partition capabilities that follow are based on benchmarking and intended as practical guidelines for planning purposes. Performance per partition will vary based on your specific configuration, and these benchmarks do not guarantee performance.
| Dimension | Capability |
|---|---|
| Ingress per partition | 5 MBps |
| Egress per partition | 15 MBps |
| Storage per partition | Unlimited |
Serverless Cloud Providers & Regions
Serverless clusters are currently available in limited regions. Please check the StreamNative Cloud console for the most up-to-date information on available regions.
Serverless Features and Usage Limits
Currently, Serverless clusters are in Public Preview. The usage limits are not strictly enforced, but you should expect some limitations. Here are some guidelines for the cluster limits:
| Dimension | Capability | Additional details |
|---|---|---|
| Ingress | Max 100 MBps | Number of bytes that can be produced to the cluster in one second. To reduce usage on this dimension, you can compress your messages. lz4 is recommended for compression. |
| Egress | Max 300 MBps | Number of bytes that can be consumed from the cluster in one second. To reduce usage on this dimension, you can compress your messages and ensure each consumer is only consuming from the topics it requires. lz4 is recommended for compression. |
| Storage | Unlimited | Number of bytes retained on the cluster, pre-replication. You can configure retention policy settings at namespace or topic level so you can control exactly how much and how long to retain data in a way that makes sense for your applications and helps control your costs. To reduce usage on this dimension, you can compress your messages and reduce your retention settings. lz4 is recommended for compression. |
| Data Entries | Max 10,000 per second | Number of data entries produced to and consumed from the cluster in one second. Each data entry represents a batch of messages. To reduce usage on this dimension, you can adjust producer batching configurations and shut down otherwise inactive clients. |
| Message size | Max 5 MB | None |
In addition to the usage limits, there are some additional limitations in features:
-
Tiered Storage is transparent, meaning you don’t need to configure it. However, Serverless clusters don’t support bringing your own bucket. If you need to use your own object storage bucket, you should consider using BYOC or BYOC Pro clusters.
-
Serverless clusters use Rapid Release Channel by default. You can’t choose a different release channel.
-
Auto-scaling is enabled by default. You don’t need to configure it.
-
Remote writes to external observability systems are not supported.

Custom maintenance windows are not available.
-
Private networking options are not available.
Dedicated Clusters
Dedicated (formerly Hosted) clusters are fully managed on StreamNative’s cloud infrastructure. They support the following capabilities:
-
Deployment in supported regions on AWS, GCP, and Azure with a 99.95% uptime SLA for Single-Zone and 99.99% for Multi-Zone.
-
Optional multi-zone high availability, spreading a cluster across three availability zones for enhanced resilience.
