Introduction
This article provides details about HCP Vault's rate limit quotas and how to address a common error associated with them.
Problem
When running API requests to HCP Vault, you may run into a similar error which relates to rate limit quotas:
hvac.exceptions.RateLimitExceeded: request path "transit/encrypt/designs":
rate limit quota exceeded, on post https://vault-cluster....
Cause
HashiCorp Cloud Platform offers Vault as a managed service. In order to ensure that the incoming requests aren't overwhelming system resources through consistent and high volume API requests (which could result in denial-of-service issues in some Vault nodes or even the entire Vault cluster), HCP imposes a rate limit quota on our resources.
The rate limit quotas are as follows. You can also find this information within the HCP Portal when creating HCP Vault clusters.
DEVELOPMENT (extra small only)
- 1 node
- Request limit 60 requests/sec*
STARTER (small only)
- 3 nodes
- Request limit 200 requests/sec*
STANDARD (small, medium, large)
- Small
- 3 nodes
- Request limit 400 requests/sec*
- Medium & Large
- 3 nodes
- Request limit not implemented at this time*
PLUS (small, medium, large)
HCP Vault Performance Replication secondary clusters do not currently have rate limiting implemented. The below rate limits for HCP Vault's Plus tier only apply to primary (or stand-alone) HCP Vault clusters.
- Small
- 3 nodes
- Request limit 400 requests/sec*
- Medium & Large
- 3 nodes
- Request limit not implemented at this time*
*Initial limits, subject to change. Rates ma be constrained by workload type and cluster resource availability and usage.
**Stay up to date with HCP changes by reviewing our change logs.
Solution
Please adjust your workflows to be within the rate limit quotas which are listed above or scale your cluster tier/size as needed.
