Connect to data
Redshift

In order to connect your AWS Athena to Kaldea, follow this guideline that will help you register the required IAM role to the system.

​
Pre-requisite

  • You must create Redshift database users for Kaldea (system/user)
CREATE USER "kaldea-system" PASSWORD {Password} SYSLOG ACCESS UNRESTRICTED;
GRANT SELECT ON pg_catalog.svv_table_info TO "kaldea-system";

// You can adjust the grant options depending on the query and table you want to use in kaldea.
// https://docs.aws.amazon.com/redshift/latest/dg/r_GRANT.html
GRANT CREATE, USAGE ON SCHEMA {SchemaName} TO "kaldea-system";
GRANT SELECT, INSERT, UPDATE, DELETE, DROP, REFERENCES
	ON ALL TABLES IN SCHEMA {SchemaName} TO "kaldea-system"

CREATE USER "kaldea-user" PASSWORD {Password}

// You can adjust the grant options depending on the query and table you want to use in kaldea.
// https://docs.aws.amazon.com/redshift/latest/dg/r_GRANT.html
GRANT CREATE, USAGE ON SCHEMA {SchemaName} TO "kaldea-user";
GRANT SELECT, INSERT, UPDATE, DELETE, DROP, REFERENCES
	ON ALL TABLES IN SCHEMA {SchemaName} TO "kaldea-user";
  • Your Redshift’s Region and Cluster

​
Configuring IAM users for Kaldea

There are 2 categories of IAM credentials that need to be prepared for Kaldea :

  • kaldea-system
  • kaldea-user

​
Create an IAM user: kaldea-system

This IAM user will be used by the Kaldea’s system to retrieve the query history

kaldea-system requires the following permissions:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
          "redshift-data:DescribeStatement",
          "redshift-data:CancelStatement",
          "redshift-data:GetStatementResult"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
          "redshift-data:ListDatabases",
          "redshift-data:ListSchemas",
          "redshift-data:ListTables",
          "redshift-data:DescribeTable",
          "redshift-data:BatchExecuteStatement",
          "redshift-data:ExecuteStatement"
      ],
      "Resource": "arn:${Partition}:redshift:${Region}:${Account}:cluster:${ClusterName}"
      //"Resource": "arn:aws:redshift:ap-northeast-2:266501888670:cluster:redshift-cluster"
    },
    {
      "Effect": "Allow",
      "Action": "redshift:GetClusterCredentials",
      "Resource": [
	  "arn:${Partition}:redshift:${Region}:${Account}:dbname:${ClusterName}/{DatabaseName}"
	  "arn:${Partition}:redshift:${Region}:${Account}:dbuser:${ClusterName}/{DbUser}"
          //"arn:aws:redshift:ap-northeast-2:266501888670:dbname:redshift-cluster-1/dev",
          //"arn:aws:redshift:ap-northeast-2:266501888670:dbuser:redshift-cluster-1/kaldea_system"
      ]
    }
  ]
}

​
Create an IAM user: kaldea-user

This IAM user is to be used for all users as default.

kaldea-user requires the following permissions:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
          "redshift-data:DescribeStatement",
          "redshift-data:CancelStatement",
          "redshift-data:GetStatementResult"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
          "redshift-data:ListDatabases",
          "redshift-data:BatchExecuteStatement",
          "redshift-data:ExecuteStatement"
      ],
      "Resource": "arn:${Partition}:redshift:${Region}:${Account}:cluster:${ClusterName}"
      //"Resource": "arn:aws:redshift:ap-northeast-2:266501888670:cluster:redshift-cluster"
    },
    {
      "Effect": "Allow",
      "Action": "redshift:GetClusterCredentials",
      "Resource": [
          "arn:${Partition}:redshift:${Region}:${Account}:dbname:${ClusterName}/{DatabaseName}"
          "arn:${Partition}:redshift:${Region}:${Account}:dbuser:${ClusterName}/{DbUser}"
          //"arn:aws:redshift:ap-northeast-2:266501888670:dbname:redshift-cluster-1/dev",
          //"arn:aws:redshift:ap-northeast-2:266501888670:dbuser:redshift-cluster-1/kaldea_user"
      ]
    }
  ]
}

​
Prepare Access Key and Secret pairs

For each IAM user, you must have the ACCESS_KEY & SECRET_KEY ready.

​
Integrating within Kaldea interface

Given the above steps are completed, you now have:

  • Access Key Pair for AWS IAM user kaldea-system
  • Access Key Pair for AWS IAM user kaldea-user
  • Your Redshift’s region and cluster
  • Database and database users kaldea_system and kaldea_user

Choose Redshift among the data source options.

Choose Redshift among the data source options.

Insert system credentials for the Kaldea’s system access.

Insert system credentials for the Kaldea’s system access.

Insert the default credential for all Kaldea users.

Insert the default credential for all Kaldea users.
