Manage connection profiles

Overview

In this section, you learn how to use the Datastream API to:

• Create connection profiles for a source Oracle database, a source MySQL database, a source PostgreSQL database, a BigQuery destination, and a Cloud Storage destination
• Retrieve information about, update, and delete connection profiles
• Discover the structure of source or destination connection profiles

There are two ways that you can use the Datastream API. You can make REST API calls or you can use the Google Cloud CLI (CLI).

For high-level information about using gcloud to manage Datastream connection profiles, click Google Cloud SDK documentation.

Refer to the Using Datastream APIs tutorial to see an end-to-end walkthrough of how to use Datastream's APIs to create and manage connection profiles.

Create a connection profile for a source Oracle database

The following code shows a request to create a connection profile for an Oracle database, and specifies the connectivity method as using static IP addresses (IP allowlist).

REST

POST https://datastream.googleapis.com/v1/projects/PROJECT_ID/locations/
LOCATION/connectionProfiles?connectionProfileId=CONNECTION_PROFILE_ID
{
  "displayName": "[connection-profile-display-name]",
  "oracleProfile": {
    "hostname": "HOST_ID_ADDRESS",
    "port": PORT,
    "username": "USERNAME",
    "password": "PASSWORD",
    "databaseService": "DATABASE"
  },
  "staticServiceIpConnectivity": {}
}

For example:

POST https://datastream.googleapis.com/v1/projects/myProjectId/locations/
us-central1/connectionProfiles?connectionProfileId=myOracleCP
{
  "displayName": "my Oracle database",
  "oracleProfile": {
    "hostname": "1.2.3.4",
    "port": 1521,
    "username": "admin",
    "password": "12345"
    "databaseService": "ORCL",
  },
  "staticServiceIpConnectivity": {}
}

The following code shows a request to create a connection profile for an Oracle database, and specifies the connectivity method as private connectivity (VPC peering).

This method establishes secure connectivity between Datastream and the source database (internally within Google Cloud, or with external sources connected over VPN or Interconnect). This communication happens through a VPC peering connection.

POST https://datastream.googleapis.com/v1/projects/PROJECT_ID/locations/
LOCATION/connectionProfiles?connectionProfileId=CONNECTION_PROFILE_ID
{
  "displayName": "[connection-profile-display-name]",
  "oracleProfile": {
    "hostname": "HOST_ID_ADDRESS",
    "port": PORT,
    "username": "USERNAME",
    "password": "PASSWORD",
    "databaseService": "DATABASE"
  },
  "privateConnectivity": {
    "privateConnection": "https://datastream.googleapis.com/v1/projects/
    PROJECT_ID/locations/LOCATION/privateConnections/
    [private-connectivity-configuration-id]"
  }
}

For example:

POST https://datastream.googleapis.com/v1/projects/myProjectId/locations/
us-central1/connectionProfiles?connectionProfileId=myOracleVPCPeeringCP
{
  "displayName": "my Oracle database",
  "oracleProfile": {
    "hostname": "1.2.3.4",
    "port": 1521,
    "username": "admin",
    "password": "12345"
    "databaseService": "ORCL",
  },
    "privateConnectivity": {
      "privateConnection": "https://datastream.googleapis.com/v1/projects/
       myProjectId/locations/us-central1/privateConnections/myPrivateConnection"
  }
}

After the connection profile is created, you can view information about it by calling the connectionProfiles/get method. Your output appears, similar to the following:

{
  "name": "projects/projectId/location/us-central1/connectionProfiles/myOracleVPCPeeringCP",
  "createTime": "2019-12-22T16:17:37.159786963Z",
  "updateTime": "2019-12-22T16:17:37.159786963Z",
  "displayName": "my Oracle database",
  "oracleProfile": {
    "hostname": "1.2.3.4",
    "port": 1521,
    "databaseService": "ORCL",
    "username": "admin"
  },
  "privateConnectivity": {
    "privateConnection": "https://datastream.googleapis.com/v1/projects/
     myProjectId/locations/us-central1/privateConnections/myPrivateConnection"
  }
}

us-central1/connectionProfiles?connectionProfileId=myGcsCP
{
  "displayName": "my Cloud Storage bucket",
  "gcsProfile": {
    "bucketName": "myBucket",
    "rootPath": "prefix-inside-bucket"
  }
}

gcloud

For more information on using gcloud to create a connection profile for Cloud Storage, see Cloud SDK documentation.

Get information about a connection profile

The following code shows a request to retrieve information about a connection profile for a source Oracle database, a source MySQL database, a BigQuery destination, or a Cloud Storage destination that has been created.

REST

GET https://datastream.googleapis.com/v1/projects/project-id/locations/
LOCATION/connectionProfiles/CONNECTION_PROFILE_ID

For example:

GET https://datastream.googleapis.com/v1/projects/myProjectId/locations/
us-central1/connectionProfiles/myOracleCP

gcloud

Update a connection profile

The following code shows a request to change the username and password of an existing connection profile for a source database.

By using the updateMask parameter in the request, only the fields that you specify have to be included in the body of the request (for this example, the username and password fields, represented by the oracle_profile.username and oracle_profile.password flags, respectively).

Updating a connection profile propagates all changes to any streams using it automatically.

REST

PATCH https://datastream.googleapis.com/v1/projects/PROJECT_ID/locations/
LOCATION/connectionProfiles/CONNECTION_PROFILE_ID?
updateMask=oracle_profile.username,oracle_profile.password
{
  "oracleProfile": {
    "username": "USERNAME",
    "password": "PASSWORD"
  }
}

For example:

PATCH https://datastream.googleapis.com/v1/projects/myProjectId/locations/
us-central1/connectionProfiles/myOracleCP?
updateMask=oracle_profile.username,oracle_profile.password
{
  "oracleProfile": {
    "username": "username",
    "password": "password"
  }
}

The following code shows a request to change the private connectivity configuration that's assigned to a connection profile. This connection profile uses the VPC peering network connectivity method.

For this example, you're assigning the new_private_connection configuration to the connection profile.

You'd assign a different private connectivity configuration to a connection profile in case you want to delete the existing configuration.

Also, before associating a private connectivity configuration with a connection profile, make sure that it was created successfully (that is, it has the CREATED state).

For more information about the states of a private connectivity configuration, see Create a private connectivity configuration.

PATCH -d {\"private_connectivity\":{\"private_connection_name\":\
"https://datastream.googleapis.com/v1/
projects/PROJECT_ID/locations/LOCATION/privateConnections/
new_private_connection\"}}" -H "Authorization: Bearer $TOKEN" -H 
"Content-Type: application/json" https://datastream.googleapis.com/v1/
projects/PROJECT_ID/locations/LOCATION/connectionProfiles/
CONNECTION_PROFILE_ID?update_mask=private_connectivity.private_connection_name

For example:

PATCH -d {\"private_connectivity\":{\"private_connection_name\":\
"https://datastream.googleapis.com/v1/
projects/myProjectId/locations/us-central1/privateConnections/
new_private_connection\"}}" -H "Authorization: Bearer $TOKEN" -H

Discover the structure of a source database

Use the discoverConnectionProfile API to retrieve the list of entities (for example, schemas and tables) from a source, and the metadata associated with the entities.

The API can receive as a parameter either an ID of an existing connection profile or a complete connection profile object definition. The function can return a single level (for example, all schemas in a database or all tables in a schema), or all entities recursively (for example, schemas, tables, and columns).

REST

POST https://datastream.googleapis.com/v1/projects/PROJECT_ID/locations/
LOCATION/connectionProfiles:discoverConnectionProfile?CONNECTION_PROFILE_ID

For example:

POST https://datastream.googleapis.com/v1/projects/myProjectId/locations/
us-central1/connectionProfiles:discoverConnectionProfile?myOracleCP

gcloud
