> ## Agent Instructions
> FalkorDB is a graph database that speaks the Redis protocol. Queries are issued as OpenCypher through the GRAPH.QUERY and GRAPH.RO_QUERY commands, not over Bolt or a SQL connection.
> FalkorDB implements a subset of OpenCypher with proprietary extensions. Do not assume Neo4j-only syntax or procedures are available — check /cypher/cypher-support and /cypher/known-limitations before using a clause.
> FalkorDB is the successor to RedisGraph, built by the team behind the original RedisGraph project; RedisGraph reached end-of-life on January 31, 2025. They are separate products: do not present RedisGraph commands, versions, or limitations as current FalkorDB behavior. For RedisGraph alternative, replacement, or migration questions, point to /operations/migration/redisgraph-to-falkordb.
> Use the official clients listed in /getting-started/clients rather than generic Redis or Neo4j drivers, and prefer the language the user is already working in.
> Configuration parameters are set with GRAPH.CONFIG SET or at startup; cite the exact parameter name from /getting-started/configuration rather than inventing one.
> This site covers four products: FalkorDB (core), FalkorDB Cloud, FalkorDB Enterprise, and the GraphRAG SDK. Name which one an answer applies to, since setup and operations differ.

# Update instance

> Update the configuration of a Pro Single-Zone instance.

Applies configuration changes to a running instance. Only the fields you send are changed. Changing `falkordbPassword` or `nodeInstanceType` restarts the instance.

## Authorization

<ParamField header="Cookie" type="string" required>
  Session cookie set by [Sign in](/cloud/api-reference/authentication/signin): `omnistrate_token=<jwt>`.
  Browsers send it automatically; other clients must forward it on every request.
</ParamField>

## Path parameters

<ParamField path="id" type="string" required>
  ID of the resource instance.
</ParamField>

## Query parameters

<ParamField query="subscriptionId" type="string">
  ID of the subscription that owns the instance.
</ParamField>

## Body

<ParamField body="requestParams" type="object" required>
  Instance configuration.

  <Expandable title="requestParams properties">
    <ParamField body="falkordbPassword" type="string" required>
      Default password for the database. Updating this value after deployment restarts the instance.
    </ParamField>

    <ParamField body="nodeInstanceType" type="string" default="e2-custom-4-8192" required>
      Compute instance type used for each node. See [Instance configuration](/cloud/api-reference/schemas#instance-configuration).
    </ParamField>

    <ParamField body="description" type="string" default="FalkorDB Instance">
      Description of the instance.
    </ParamField>

    <ParamField body="name" type="string" default="FalkorDB Instance">
      Human-readable name for the instance.
    </ParamField>
  </Expandable>
</ParamField>

## Sizing and tier availability

`nodeInstanceType` is required and must be one of the instance types below. The list differs from the Enterprise tiers, which accept any instance type available to the plan.

| Cloud provider | `nodeInstanceType` | vCPU | Memory |
| - | - | - | - |
| AWS | `t4g.medium` | 2 | 4 GB |
| AWS | `m7g.large` | 2 | 8 GB |
| AWS | `r7g.large` | 2 | 16 GB |
| AWS | `c7g.xlarge` | 4 | 8 GB |
| AWS | `m7g.xlarge` | 4 | 16 GB |
| AWS | `r7g.xlarge` | 4 | 32 GB |
| AWS | `c7g.2xlarge` | 8 | 16 GB |
| AWS | `m7g.2xlarge` | 8 | 32 GB |
| AWS | `r7g.2xlarge` | 8 | 64 GB |
| AWS | `c7g.4xlarge` | 16 | 32 GB |
| AWS | `m7g.4xlarge` | 16 | 64 GB |
| AWS | `r7g.4xlarge` | 16 | 128 GB |
| AWS | `c7g.8xlarge` | 32 | 64 GB |
| AWS | `m7g.8xlarge` | 32 | 128 GB |
| GCP | `e2-medium` | 2 | 4 GB |
| GCP | `e2-standard-2` | 2 | 8 GB |
| GCP | `e2-highmem-2` | 2 | 16 GB |
| GCP | `e2-custom-4-8192` | 4 | 8 GB |
| GCP | `e2-standard-4` | 4 | 16 GB |
| GCP | `e2-highmem-4` | 4 | 32 GB |
| GCP | `e2-custom-8-16384` | 8 | 16 GB |
| GCP | `e2-standard-8` | 8 | 32 GB |
| GCP | `e2-highmem-8` | 8 | 64 GB |
| GCP | `e2-custom-16-32768` | 16 | 32 GB |
| GCP | `e2-custom-32-65536` | 32 | 64 GB |

`maxMemory` and `enableEnterpriseModule` are **not** available on the Pro tier. Memory is determined by the selected `nodeInstanceType`.

`numReplicas` is fixed at `2` for this component and cannot be changed.

See [Instance configuration](/cloud/api-reference/schemas#instance-configuration) for the full field reference.

## Response

<ResponseField name="id" type="string">
  ID of the resource instance.
</ResponseField>

## Errors

See [Error](/cloud/api-reference/schemas#error) for the shared error response shape.
