Stream Processors

Atlas charges per hour per stream processor, where the hourly rate is determined by the tier of the stream processor. Atlas Stream Processing bills users for stream processors only when they are running. Billing is recorded in one-second increments.

Important

SP10 and SP30 instances created before October 22nd, 2025 operate and bill users according to the legacy worker model. To learn more, see the worker model section of the Atlas Stream Processing architecture overview.

The allocated vCPU and RAM vary depending on your stream processor tier:

Stream Processor Tier	vCPU	RAM	Max Parallelism
`SP2`	0.25	512 MB	1
`SP5`	0.5	1 GB	2
`SP10`	1	2 GB	8
`SP30`	2	8 GB	16
`SP50`	8	32 GB	64

Note

Exceptions to Stream Processing Workspace Cost

Atlas doesn't charge for storage.

Updated Data Transfer Pricing

New data transfer pricing for Atlas Stream Processing takes effect on December 3, 2025 for S3- and MongoDB-based sinks. Current data transfer pricing applies to usage prior to this date. The updated pricing varies by provider and transfer type, making intra-region and inter-region data transfer more affordable than the current pricing structure.

Atlas charges for all egress data transfer based on the transfer type and destination. Data transfer pricing varies by cloud provider and follows a tiered structure from lowest to highest cost.
