Updating a Greenplum® cluster's configuration

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To change the host class for a cluster:

1. View the description of the CLI command for updating a cluster:

   yc managed-greenplum cluster update --help
   

2. Request a list of available classes (the ZONE IDS column lists the availability zones where you can select the appropriate class):

   • For master hosts:

     yc managed-greenplum resource-preset list master
     

   • For segment hosts:

     yc managed-greenplum resource-preset list segment
     

   +-------------+--------------------------------+--------------------------------+-------+----------+--------------------+---------------------+
   |     ID      |            ZONE IDS            |           DISK TYPES           | CORES |  MEMORY  | HOST COUNT DIVIDER | MAX SEGMENT IN HOST |
   +-------------+--------------------------------+--------------------------------+-------+----------+--------------------+---------------------+
   | i2.2xlarge  | ru-central1-a, ru-central1-b   | local-ssd,                     |    16 | 128.0 GB |                  1 |                   0 |
   |             |                                | network-ssd-nonreplicated      |       |          |                    |                     |
   | ...                                                                                                                                         |
   +-------------+--------------------------------+--------------------------------+-------+----------+--------------------+---------------------+
   

3. Specify the relevant classes in the cluster update command:

   yc managed-greenplum cluster update <cluster_name_or_ID> \
       --master-config resource-id=<master_host_class_ID> \
       --segment-config resource-id=<segment_host_class_ID>
   

   Yandex MPP Analytics for PostgreSQL will run the update host class command for the cluster.

1. Open the current Terraform configuration file that defines your infrastructure.

   For more information about creating this file, see Creating clusters.

   For a complete list of configuration fields you can edit for a Yandex MPP Analytics for PostgreSQL cluster, see the Terraform provider guide.

2. In the Yandex MPP Analytics for PostgreSQL cluster description, edit the value of the resource_preset_id attribute under master_subcluster.resources or segment_subcluster.resources:

   resource "yandex_mdb_greenplum_cluster" "<cluster_name>" {
     ...
     master_subcluster {
       resources {
         resource_preset_id = "<host_class>"
         ...
       }
     }
     segment_subcluster {
       resources {
         resource_preset_id = "<host_class>"
         ...
       }
     }
   }
   

3. Make sure the settings are correct.

   1. In the command line, navigate to the directory that contains the current Terraform configuration files defining the infrastructure.

   2. Run this command:

      terraform validate
      

      Terraform will show any errors found in your configuration files.

4. Confirm updating the resources.

   1. Run this command to view the planned changes:

      terraform plan
      

      If you described the configuration correctly, the terminal will display a list of the resources to update and their parameters. This is a verification step that does not apply changes to your resources.

   2. If everything looks correct, apply the changes:

      1. Run this command:

         terraform apply
         

      2. Confirm updating the resources.

      3. Wait for the operation to complete.

   Warning

   The Terraform provider limits the amount of time for all Yandex MPP Analytics for PostgreSQL cluster operations to complete to 120 minutes.

   Operations exceeding the set timeout are interrupted.

   How do I change these limits?

   Add the timeouts block to the cluster description, for example:

   resource "yandex_mdb_greenplum_cluster" "<cluster name>" {
     ...
     timeouts {
       create = "1h30m" # 1 hour 30 minutes
       update = "2h"    # 2 hours
       delete = "30m"   # 30 minutes
     }
   }
   

1. Get an IAM token for API authentication and save it as an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Call the Cluster.Update method, e.g., via the following cURL request:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the updateMask parameter as a single comma-separated string.

   curl \
       --request PATCH \
       --header "Authorization: Bearer $IAM_TOKEN" \
       --header "Content-Type: application/json" \
       --url 'https://mdb.api.cloud.yandex.net/managed-greenplum/v1/clusters/<cluster_ID>' \
       --data '{
                 "updateMask": "masterConfig.resources.resourcePresetId,segmentConfig.resources.resourcePresetId",
                 "masterConfig": {
                   "resources": {
                     "resourcePresetId": "<host_class>"
                   }
                 },
                 "segmentConfig": {
                   "resources": {
                     "resourcePresetId": "<host_class>"
                   }
                 }
               }'
   

   Where:

   • updateMask: List of settings to update as a single string, separated by commas.

   • masterConfig.resources.resourcePresetId and segmentConfig.resources.resourcePresetId: New host class for master and segment hosts.

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

3. Check the server response to make sure your request was successful.

1. Get an IAM token for API authentication and save it as an 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 ClusterService.Update call and send the following request, e.g., via gRPCurl:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the update_mask parameter as an array of paths[] strings.

   Format for listing settings

   "update_mask": {
       "paths": [
           "<setting_1>",
           "<setting_2>",
           ...
           "<setting_N>"
       ]
   }
   

   grpcurl \
       -format json \
       -import-path ~/cloudapi/ \
       -import-path ~/cloudapi/third_party/googleapis/ \
       -proto ~/cloudapi/yandex/cloud/mdb/greenplum/v1/cluster_service.proto \
       -rpc-header "Authorization: Bearer $IAM_TOKEN" \
       -d '{
             "cluster_id": "<cluster_ID>",
             "update_mask": {
               "paths": [ 
                 "master_config.resources.resource_preset_id",
                 "segment_config.resources.resource_preset_id"
               ]
             },
             "master_config": {
               "resources": {
                 "resource_preset_id": "<host_class>"
               }
             },
             "segment_config": {
               "resources": {
                 "resource_preset_id": "<host_class>"
               }
             }
           }' \
       mdb.api.cloud.yandex.net:443 \
       yandex.cloud.mdb.greenplum.v1.ClusterService.Update
   

   Where:

   • update_mask: List of settings to update as an array of paths[] strings.

   • master_config.resources.resource_preset_id and segment_config.resources.resource_preset_id: New host class for master and segment hosts.

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

4. Check the server response to make sure your request was successful.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To increase your cluster storage size:

1. View the description of the CLI command for updating a cluster:

   yc managed-greenplum cluster update --help
   

2. Specify the required storage size for master or segment hosts in the cluster update command (at least as large as disk_size in the cluster properties):

   yc managed-mysql cluster update <cluster_name_or_ID> \
      --master-config disk-size <storage_size_in_GB> \
      --segment-config disk-size <storage_size_in_GB>
   

1. Open the current Terraform configuration file that defines your infrastructure.

   For more information about creating this file, see Creating clusters.

   For a complete list of configuration fields you can edit for a Yandex MPP Analytics for PostgreSQL cluster, see the Terraform provider guide.

2. In the Yandex MPP Analytics for PostgreSQL cluster description, edit the values of the disk_type_id and disk_size attributes under master_subcluster.resources or segment_subcluster.resources:

   resource "yandex_mdb_greenplum_cluster" "<cluster_name>" {
     ...
     master_subcluster {
       resources {
         disk_type_id = "<disk_type>"
         disk_size    = <storage_size_in_GB>
         ...
       }
     }
     segment_subcluster {
       resources {
         disk_type_id = "<disk_type>"
         disk_size    = <storage_size_in_GB>
         ...
