Limits

We’d love for you to have unlimited joy building on Bijection but engineering practicalities dictate a few limits. This page outlines current limits in the Bijection ecosystem. Many of these limits will become more permissive over time. Please get in touch if any are prohibitive for your application. Limits are applied per team unless stated otherwise. Business and Enterprise plans use custom resource allocations unless otherwise noted below. Free and Starter share the same S16 provisioned performance tier. Free has hard resource caps, while Starter can exceed its included resource amounts with usage-based pricing. Unless otherwise noted, pricing quoted on this page is for US regions. EU region pricing is 1.3x.

Deployment Classes

Bijection has four deployment classes that each have different concurrency limits. These limits are meant to scale as your traffic grows. S stands for serverless and D stands for dedicated. Dedicated deployments run on their own exclusive database hardware. The number represents the number of concurrent queries that can be running on a deployment at a given time. As the concurrent query limit gets larger, other internal limits are scaled proportionately to allow your deployments to handle larger workloads. Below are the deployment classes that each plan has access to:

Free/Starter: S16
Professional: S256
Business: S16, S256, D1024, or D2048
Enterprise: S16, S256, D1024, or D2048

Free and Starter are limited to S16 with a team deployment limit of 40. Professional plans get S256 with a team deployment limit of 300. Business and Enterprise can choose their class on a per-deployment basis. There is a per-deployment fee which varies by deployment class. The deployment fee is waived for paused and idle deployments. Idle deployments are defined as those that have not had any function calls for 30 days.

Capabilities

	S16	S256	D1024	D2048
Concurrent sessions	1,000	10,000	100,000	200,000
Query cache	1 GB shared	1 GB shared	2 GB dedicated	4 GB dedicated

Backup/restore	Logical	Logical	High-speed physical	High-speed physical
SLA (Business/Enterprise only)	99.9%	99.9%	99.95%	99.95%

Concurrent Function Executions

Number of functions you can run at a time for each function type.

	S16	S256	D1024^*	D2048^*
Queries	16	256	1024	2048
Mutations	16	256	512	1024
Mutation write throughput limit	4 MiB	8 MiB	32 MiB	64 MiB
Bijection runtime actions and HTTP actions	64	512	1024	2048
Node actions	64	256	1024	2048
Scheduled jobs	8	256	512	1024

^* Limits can be increased for Business and Enterprise plan customers on a case-by-case basis. Send us a support message through the console to discuss your needs. Usually this is only needed if your product has highly bursty traffic.

Execution time and scheduling

Query/mutation execution time	1 second	Limit applies only to user code and doesn’t include database operations.
Bijection runtime action execution time	30 minutes
Node runtime action execution time	10 minutes
Scheduled functions	1000	The number of other functions a single mutation can schedule.

If any of these limits don’t work for you, let us know! Please see our Free, Starter, and Professional pricing page and Business and Enterprise pricing page for current resource limits. After these limits are hit on the Free plan, new mutations that attempt to commit more insertions or updates may fail. Starter, Professional, Business, and Enterprise plans can exceed their included resource amounts with usage-based pricing, subject to deployment-class limits.
