How Does Heroku Store Data?

Heroku is a cloud-based Platform-as-a-Service, also known as a PaaS. The service takes care of all the setup work required to create an application. Applications created on Heroku run inside containers. In the Heroku system, these containers are known as "dynos". The individual running the Heroku account can handle all aspects of the dyno, including resource allocation and special permissions.

Every dyno can support eight different programming languages within the Heroku system. Theselanguages include:

Ruby
Node.js
PHP
GO
Clojure
Java
Python
Scala

The applications created on Heroku require a database. The default database option within Heroku is Heroku Postgres. Heroku Postgres is a relational database based onPostgreSQL.

Using the Heroku Postgres Database

So the Heroku Postgres database is an open-source SQL database running on PostgreSQL, but how is it used? Well, there are somepowerful features that can be used through this system. Some of the most powerful tools in relation to the Heroku Postgres database are Forks, Followers, and Dataclips.

Forks

Heroku Postgres allows for the forking of a database, just like forking source code. This means that the database can be cloned with a single command. This tool also allows for the testing of new schema migrations by forking a production database and running new migrations against the fork.

Followers

Followers on Heroku Postgres are read-only replicas of databases that stay up-to-date with changes and can be queried. Without this Heroku Postgres tool, setting up and maintaining replication can be a very difficult and specialized task. However, through the followers tool, this task is made simple through horizontal scalability that distributes database read traffic.

Dataclips

Dataclips are another powerful tool on Heroku Postgres. They allow anyone who is familiar with SQL to easily create reports against live production data. The results can then be securely shared with anyone through a unique URL. This tool takes the complexity of dashboards and analytics tools out of the important data-sharing process.

Where to Use PostgreSQL

A PostgreSQL can provide a great deal of value to developers with its powerful query, operational speed, and overall stability. Three of the most useful databases to use PostgreSQL are an operational database, a data warehouse, and a reporting database.

Operational Database

PostgreSQL is perfect for use in an operational database as it provides unbeatable reliability. It is also responsive, scalable, and stable, allowing for effortless dev, staging, and backup.

Data Warehouse

PostgreSQL is the standard for most ETL systems. Therefore, it is also very popular for data warehousing. Its scalability and query power make it ideal for terabytes of data.

Reporting Database

The query flexibility of PostgreSQL makes it suitable to dive deep into your data. The ability to query multiple PostgreSQL instances in a single query also allows for data to be brought together across multiple organizations. This makes PostgreSQL extremely useful as a reporting database.
