To be successful in this role you need technical expertise in PostgreSQL, Aurora, and RedShift to make sure our databases are performant, secure, and recoverable. They troubleshoot and consult with other support teams to resolve issues and implement process improvements to avoid reoccurrences They effectively administer the databases to ensure that we are satisfying our customer requirements. They are part of a senior technical team to ensure that our databases are secure, highly available, and recoverable. Senior PostgreSQL and AWS Database Administrators participate in the design, build, run, and modernisation of our databases. If you're passionate about developing your career, while helping others along the way, come join the Broadridge team. Industry: Financial Services, TechnologyĪt Broadridge, we've built a culture where the highest goal is to empower others to accomplish more.You can also perform a couple of simple queries on each database to make sure the results match up.We enable better financial lives by powering investing, governance, & communications for our clients & the financial services industry. A few things to check are the number of tables in both databases and the extensions that exist on each. Validationīefore deleting your Heroku PostgreSQL add-on, it’s best to do some sanity checks and make sure all the data was transferred correctly. With the connection string we created earlier.Ĭongratulations! Your Heroku application is now using the RDS instance! You can now scale your application dynos back up to normal levels and turn off maintenance mode. We’ll then use this connection string in a command on the EC2 instance we provisioned earlier to generate our backup directory. ![]() With the name found, we can then get the connection string of the specified database using the following command on the same Heroku application heroku pg:credentials:url Look for DATABASE_URL or HEROKU_POSTGRESQL_URL, these will be the name of the database. Begin by grabbing the name of the database that you want to migrate by using the following command on your Heroku application to list all of the environment variables heroku config To create the backup, we’ll generate a backup directory on the EC2 instance we provisioned earlier based on the data stored in the Heroku PostgreSQL add-on. To list the type and quantity of each dyno. If you aren’t sure what type of dynos are running on your application, you can use this heroku ps To ensure that no changes to the database are being made while the backups are created, put your Heroku application into maintenance mode and scale down all dynos: heroku maintenance:onĬan be used to do this. You should add the security group of the EC2 instance to the inbound rules of the RDS instance security group. I provisioned a db.t3.xlarge instance to take advantage of parallel jobs and speed up the process. RDSĪn RDS instance sharing the same PostgreSQL version should be provisioned before the migration process. ![]() You can connect to the EC2 instance a few ways, but I recommend generating a key pair to connect using SSH. ![]() PostgreSQL should be installed on your EC2 instance and the version should match the version of your Heroku PostgreSQL add-on. I provisioned a t3.xlarge instance to take advantage of multiple jobs and speed up the migration process. To do this we will use an EC2 instance to generate the data dump. Heroku has its resources hosted on AWS, so staying in their network will make things faster. I’ll share how I was able to successfully complete a migration from Heroku PostgreSQL to RDS. That’s where Amazon’s Relational Database Service (RDS) comes in! RDS allows much more granular control of the size and performance of your database, and it’s generally cheaper. ![]() Using Heroku, it’s quick and easy to add a PostgreSQL database to your application, but over time these Heroku add-ons may not fit your needs.
