Creating an external JDBC data source

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

To create an external JDBC data source:

1. View the description of the CLI command to create a data source:

   yc managed-greenplum pxf-datasource create jdbc --help
   

2. Configure the data source:

   yc managed-greenplum pxf-datasource create jdbc <external_data_source_name> \
      --cluster-id=<cluster_ID> \
      --driver=<driver_address> \
      --url=<database_URL> \
      --user=<username> \
      --password=<password>
   

   Where:

   • cluster-id: Cluster ID. You can get it with a list of clusters in the folder.

   • driver: JDBC driver class in Java. The possible values are:

     • com.simba.athena.jdbc.Driver
     • com.clickhouse.jdbc.ClickHouseDriver
     • com.ibm.as400.access.AS400JDBCDriver
     • com.microsoft.sqlserver.jdbc.SQLServerDriver
     • com.mysql.cj.jdbc.Driver
     • org.postgresql.Driver
     • oracle.jdbc.driver.OracleDriver
     • net.snowflake.client.jdbc.SnowflakeDriver
     • io.trino.jdbc.TrinoDriver

   • url: Database URL. Examples:

     • jdbc:mysql://mysqlhost:3306/testdb: For a local MySQL® DB.
     • jdbc:postgresql://c-<cluster_ID>.rw.mdb.yandexcloud.net:6432/db1: For a Yandex Managed Service for PostgreSQL cluster. The address contains a special FQDN of the master host in the cluster.
     • jdbc:oracle:thin:@host.example:1521:orcl: For an Oracle DB.

   • user: DB owner username.

   • password: DB user password.

   You can also configure advanced settings.

1. Get an IAM token for API authentication and put it into the environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Use the PXFDatasource.Create method and make a request, e.g., via cURL:

   curl \
       --request POST \
       --header "Authorization: Bearer $IAM_TOKEN" \
       --header "Content-Type: application/json" \
       --url 'https://mdb.api.cloud.yandex.net/managed-greenplum/v1/clusters/<cluster_ID>/pxf_datasources' \
       --data '{
                 "datasource": {
                   "name": "<external_data_source_name>",
                   "jdbc": {
                     "driver": "<driver_address>",
                     "url": "<database_URL>",
                     "user": "<user_login>",
                     "password": "<user_password>",
                     ...
                   }
                 }
               }'
   

   Where:

   • name: External data source name.
   • jdbc: External data source settings. Configure at least one optional setting.

   You can get the cluster ID with a list of clusters in the folder.

3. View the server response to make sure the request was successful.

1. Get an IAM token for API authentication and put it into the environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Clone the cloudapi repository:

   cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
   

   Below, we assume the repository contents are stored in the ~/cloudapi/ directory.

3. Use the PXFDatasourceService.Create call and make a request, e.g., via gRPCurl:

   grpcurl \
       -format json \
       -import-path ~/cloudapi/ \
       -import-path ~/cloudapi/third_party/googleapis/ \
       -proto ~/cloudapi/yandex/cloud/mdb/greenplum/v1/pxf_service.proto \
       -rpc-header "Authorization: Bearer $IAM_TOKEN" \
       -d '{
             "cluster_id": "<cluster_ID>"
             "datasource": {
               "name": "<external_data_source_name>",
               "jdbc": {
                 "driver": "<driver_address>",
                 "url": "<database_URL>",
                 "user": "<user_login>",
                 "password": "<user_password>",
                 ...
               }
             }
           }' \
       mdb.api.cloud.yandex.net:443 \
       yandex.cloud.mdb.greenplum.v1.PXFDatasourceService.Create
   

   Where:

   • name: External data source name.
   • jdbc: External data source settings. Configure at least one optional setting.

   You can get the cluster ID with a list of clusters in the folder.

4. View the server response to make sure the request was successful.
