Steps:

1. In your RDS dashboard, click Launch a DB instance. 

   NOTE: The RDS instance must be launched in the same Amazon region as the Trifacta node.

2. For Select Engine: Select PostgresSQL.
3. For Production?:  Choose Yes if you are deploying the database for a production instance of the Trifacta platform.  Otherwise, select No. 
4. DB Engine: postgres

5. For the DB details, see below:

   NOTE: Except as noted below, properties should be specified according to your enterprise requirements.

   1. Instance Specifications:

      1. License Model: postresql-license
      2. DB Engine Version: For more information on the supported versions of PostgreSQL, see System Requirements.

      3. Allocated Storage: at least 10 GB

6. For Advanced Settings, please apply the following settings:

   1. Network and Security:

      1. VPC security group must allow for access from the Trifacta platform. 

   2. Database Options:

Configure the Trifacta platform for RDS

Please complete the following steps to integrate the Trifacta platform with the DB instance you just created.

Steps:

1. In the RDS console, you must find the Public DNS endpoint for the RDS instance you created: 

   1. Under Instances, expand the name of the instance you created.

   2. The DNS endpoint should be listed under the name in the Endpoint section.

2. Set the host for each database to the Public DNS endpoint for the RDS instance:
   
   

   Database	Property
   Main database	webapp.db.host
   Jobs database	batch-job-runner.db.host
   Scheduling database	scheduling-service.database.host
   Time-based Trigger database	time-based-trigger-service.database.host

3. To set custom database names, usernames, and passwords:

   1. Edit  /opt/trifacta/conf/trifacta-conf.json. 

   2. For each database below, you can review the database name, username, and password. 

      Database	Property
      Main database	webapp.db.name
      	webapp.db.username
      	webapp.db.password
      Jobs database	batch-job-runner.db.name
      	batch-job-runner.db.username
      	batch-job-runner.db.password
      Scheduling database	scheduling-service.database.name
      	scheduling-service.database.user
      	scheduling-service.database.password
      Time-Based Trigger database	time-based-trigger-service.database.name
      	time-based-trigger-service.database.user
      	time-based-trigger-service.database.password

   3. Make changes in the file as needed and save.

Install the Databases

Steps:

1. Run the following script, which builds the four databases and specifies the appropriate roles for each database, based on the parameters you have specified in  trifacta-conf.json:

   NOTE: This script must be run as the root user or via sudo superuser.

   /opt/trifacta/bin/setup-utils/db/trifacta-create-postgres-roles-dbs.sh

2. Login to the application.
3. Create a flow and import a dataset into it. If you are able to wrangle the dataset, the integration is working. 

Logging

1. To review database logs in RDS, locate the Instance details page in the RDS console.
2. Click Recent Events and Logs.
3. If your account has the appropriate permissions, all Trifacta database logs are available here.
