An Operation resource. For more information, see Operation.

Field

Description

id

string

ID of the operation.

description

string

Description of the operation. 0-256 characters long.

createdAt

string (date-time)

Creation timestamp.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

createdBy

string

ID of the user or service account who initiated the operation.

modifiedAt

string (date-time)

The time when the Operation resource was last modified.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

done

boolean

If the value is false, it means the operation is still in progress.
If true, the operation is completed, and either error or response is available.

metadata

MoveClusterMetadata

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any.

error

Status

The error result of the operation in case of failure or cancellation.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

response

Cluster

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is google.protobuf.Empty.
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

MoveClusterMetadata

Field

Description

clusterId

string

ID of the PostgreSQL cluster being moved.

sourceFolderId

string

ID of the source folder.

destinationFolderId

string

ID of the destnation folder.

Status

The error result of the operation in case of failure or cancellation.

Field

Description

code

integer (int32)

Error code. An enum value of google.rpc.Code.

message

string

An error message.

details[]

object

A list of messages that carry the error details.

Cluster

the Concepts section of the documentation.

Field

Description

id

string

ID of the PostgreSQL cluster.
This ID is assigned by MDB at creation time.

folderId

string

ID of the folder that the PostgreSQL cluster belongs to.

createdAt

string (date-time)

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

name

string

Name of the PostgreSQL cluster.
The name is unique within the folder. 1-63 characters long.

description

string

Description of the PostgreSQL cluster. 0-256 characters long.

labels

object (map<string, string>)

Custom labels for the PostgreSQL cluster as key:value pairs.
Maximum 64 per resource.

environment

enum (Environment)

Deployment environment of the PostgreSQL cluster.

  • PRODUCTION: Stable environment with a conservative update policy:

  • PRESTABLE: Environment with more aggressive update policy: new versions
    are rolled out irrespective of backward compatibility.

monitoring[]

Monitoring

Description of monitoring systems relevant to the PostgreSQL cluster.

config

ClusterConfig

Configuration of the PostgreSQL cluster.

networkId

string

ID of the network that the cluster belongs to.

health

PASSWORD_ENCRYPTION_MD5 or PASSWORD_ENCRYPTION_SCRAM_SHA_256. The default is PASSWORD_ENCRYPTION_MD5.

  • PASSWORD_ENCRYPTION_MD5: The method md5 uses a custom less secure challenge-response mechanism. It prevents password sniffing and avoids storing passwords on the server in plain text but provides no protection if an attacker manages to steal the password hash from the server. Also, the MD5 hash algorithm is nowadays no longer considered secure against determined attacks.
  • PASSWORD_ENCRYPTION_SCRAM_SHA_256: The method scram-sha-256 performs SCRAM-SHA-256 authentication, as described in RFC 7677. It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure.
    This is the most secure of the currently provided methods, but it is not supported by older client libraries.

  • PASSWORD_ENCRYPTION_MD5: The method md5 uses a custom less secure challenge-response mechanism. It prevents password sniffing and avoids storing passwords on the server in plain text but provides no protection if an attacker manages to steal the password hash from the server. Also, the MD5 hash algorithm is nowadays no longer considered secure against determined attacks.
  • PASSWORD_ENCRYPTION_SCRAM_SHA_256: The method scram-sha-256 performs SCRAM-SHA-256 authentication, as described in RFC 7677. It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure.
    This is the most secure of the currently provided methods, but it is not supported by older client libraries.

It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure.
    This is the most secure of the currently provided methods, but it is not supported by older client libraries.

It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure.
    This is the most secure of the currently provided methods, but it is not supported by older client libraries.

  • PASSWORD_ENCRYPTION_MD5: The method md5 uses a custom less secure challenge-response mechanism. It prevents password sniffing and avoids storing passwords on the server in plain text but provides no protection if an attacker manages to steal the password hash from the server. Also, the MD5 hash algorithm is nowadays no longer considered secure against determined attacks.
  • PASSWORD_ENCRYPTION_SCRAM_SHA_256: The method scram-sha-256 performs SCRAM-SHA-256 authentication, as described in RFC 7677. It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure.
