Cluster replica
Create and manage cluster replicas.
Part of the API reference collection
This page is part of the Crunchy Bridge API reference, and primarily meant to act as an exhaustive guide for technical integrations which are already in progress. To understand the basics of using the API, see API concepts and getting started.
The Cluster
API resource
A database cluster.

---|---|---|---|
id | string in EID format |
The unique ID of the cluster. |
|
cluster_id | âś” | string in EID format |
In the case of a replica, the ID of the primary cluster. Always |
cpu | integer |
The number of CPU units on the cluster’s instance. |
|
created_at | string of date/time formatted as RFC 3339 |
Time at which the cluster was originally created. |
|
disk_usage | object of type ClusterDiskUsage |
Contains information on the cluster’s current disk usage. This data is collected about once a day, and isn’t guaranteed to be perfectly fresh. For a new cluster, it may also not have been collected yet at all, in which case this field will be |
|
environment | âś” | enum string |
The type of environment which the cluster belongs to. This is largely for informational purposes, but may affect the cluster’s display and interaction from Bridge tools. For example, a value of Enum |
host | string |
The hostname of the cluster. |
|
is_ha | boolean |
Whether the cluster is high availability, meaning that it has a secondary it can fail over to quickly in case the primary becomes unavailable. |
|
is_protected | boolean |
Whether the cluster is protected. Protected clusters can’t be destroyed until their protected flag is removed (which can be done via the “update cluster” endpoint). |
|
is_suspended | boolean |
Indicates whether the cluster is currently in a suspended state, meaning that while its disk is available, it doesn’t currently have a running virtual machine. |
|
maintenance_Âwindow_Âstart | âś” | integer |
The hour of day which a maintenance window can possibly start. This should be an integer from |
major_version | integer |
The cluster’s major Postgres version. For example, |
|
memory | number |
The total amount of memory available on the cluster’s instance in GB (gigabytes). This is normally a whole integer, but may be fractional for the case of smaller hobby instances that have less than a gigabyte of memory. |
|
name | string |
A human-readable name for the cluster. |
|
network_id | âś” | string in EID format |
The ID of the network where the cluster is located. |
plan_id | string |
The ID of the cluster’s plan. Determines instance, CPU, and memory. |
|
postgres_Âversion_Âid | string in EID format |
The ID of the cluster’s major Postgres version. |
|
provider_id | string |
The cloud provider where the cluster is located. |
|
region_id | string |
The provider region where the cluster is located. |
|
replicas | array of object of type Cluster |
Replicas for the cluster. Always empty for a non-primary cluster. |
|
storage | integer |
The amount of storage available to the cluster in GB (gigabytes). |
|
tailscale_active | boolean |
Indicates whether tailscale is active for the cluster. |
|
team_id | string in EID format |
The ID of the team that the cluster belongs to. |
|
updated_at | string of date/time formatted as RFC 3339 |
Time at which the cluster was last updated. |

The ClusterDiskUsage
object
Contains information about a cluster's disk usage.
Name | Nullable | Type | Description |
---|---|---|---|
disk_available_mb | integer |
Available disk left in MB (megabytes). |
|
disk_Âtotal_Âsize_Âmb | integer |

Create cluster replica
Create a read-replica for an existing database cluster.
POST /clusters/{cluster_id}/replicas
Request
Path parameters
- cluster_id: The ID of the cluster to create a replica for.
Request body schema
Content type: application/json
Name | Required | Type | Description |
---|---|---|---|
name | âś” | string |
A human-readable name for the replica. |
network_id | string in EID format |
The ID of the network where the new replica should be created. The cluster is created in the same network as its primary if left empty. |
|
plan_id | string |
The ID of the plan with which to create the replica. Determines instance, CPU, and memory. If not specified, defaults to the target cluster’s plan. If specified, then |
|
provider_id | string |
The cloud provider in which to create the replica. If not specified, defaults to the target cluster’s provider. If specified, then |
|
region_id | string |
The provider region in which to create the replica. If not specified, defaults to the target cluster’s region. If specified, then |
Example request body
{
"name": "crunchy-production-replica",
"plan_id": "standard-64"
}
cURL example
curl -X POST https://api.crunchybridge.com/clusters/{cluster_id}/replicas
-H "Authorization: Bearer $CRUNCHY_API_KEY"
-H "Content-Type: application/json"
-d '{"name":"crunchy-production-replica","plan_id":"standard-64"}'
Response
Status: 201
Responds with the standard Cluster
API resource.
Detach replica
Detach a replica from its primary.
The replica detaches asynchronously and calling this endpoint multiple times before the final detach resolves will no-op idempotently. Calling detach on a non-replica is an error.
PUT /clusters/{cluster_id}/actions/detach
Request
Path parameters
- cluster_id: The ID of the cluster to detach.
cURL example
curl -X PUT https://api.crunchybridge.com/clusters/{cluster_id}/actions/detach
-H "Authorization: Bearer $CRUNCHY_API_KEY"
Response
Status: 200
Responds with the standard Cluster
API resource.
Destroy cluster replica
Delete a read-replica database cluster.
DELETE /clusters/{cluster_id}/replicas/{replica_id}
Request
Path parameters
- cluster_id: Unique ID of the cluster which the replica belongs to.
- replica_id: Unique ID of the replica to destroy.
cURL example
curl -X DELETE https://api.crunchybridge.com/clusters/{cluster_id}/replicas/{replica_id}
-H "Authorization: Bearer $CRUNCHY_API_KEY"
Response
Status: 200
Responds with the standard Cluster
API resource.
