Scale the deployment

The scale: section of the deployment manifest allows allocating additional computing resources for the squid addons and services. This option is only available for Premium Aquarium accounts. To apply for a Premium account, fill the form.

The manifest supports the following scaling options:

Addons

Each addon is optional. In particular, the postgres addon should be removed if the squid only writes data to external sinks.

For postgres:

• storage: the size of the allocated disk, in memory resource units, e.g. 100G.
• profile: small | medium | large. Specifies the allocated resources for the pod running the Postgres instance. The default is small.

The profile specifications for postgres are as follows:

• small: 1 vCPU, 1Gi RAM
• medium: 2 vCPU, 2Gi RAM
• large: 4 vCPU, 4Gi RAM

Services

The api service is optional (e.g. if the squid only writes data to external sinks)

processor:

• profile: small | medium | large. The machine specification (with extra vCPU and RAM). Default: small.

api:

• profile: small | medium | large. The machine specification (with extra vCPU and RAM). Default: small.
• replicas: the number of the API gateway replicas. The traffic is automatically load balanced between the replicas.

Each squid has a canonical (prod) API endpoint exposed https://squid.subsquid.io/${name}/graphql, see promote to production. Each version is independently served at https://squid.subsquid.io/${name}/v/${version}/graphql.

The profile specifications for the API server replicas are as follows:

• small: 0.5 vCPU, 256Mi RAM
• medium: 1 vCPU, 512Mi RAM
• large: 2 vCPU, 1Gi RAM

Example

squid.yaml

scale:
  addons:
     postgres:
         storage: 100G
         profile: medium
  processor:
     profile: medium
  api:
     profile: large
     # load-balance three replicas
     replicas: 3
