PostgreSQL, also known as Postgres, is an extendible feature-rich Object-Relational Database Management System that is almost 100% SQL standards-compliant and released as open source software under a permissive license. Much of the content in this tutorial is based on experience I acquired working for HATCH Studio, even though I’m just shy of ten months there. My first assignments involved improving some data structures we used internally and led to a team discussion about moving from a document-based database to a more traditional relational database in the face of some challenges. Next, we held a brainstorming session where we assembled our backend team to analyze our situation and discuss options. I already had some limited experience using PostgreSQL with pgx for a pet project and was pleased to discover that the rest of the team also saw PostgreSQL as an excellent choice for meeting our needs: great developer experience, performance, reliability, and scalability.įor our search infrastructure, we started using Amazon OpenSearch Service. We listen to PostgreSQL database changes via its Logical Streaming Replication Protocol and ingest data into our OpenSearch/ Elasticsearch search engine through a lightweight connector built in-house.
It works similar to hooking Apache Kafka, but is easier to use and allows us to move faster without breaking things: running integration tests on a developer machine takes only seconds: much of which is an overkill time.Sleep() so we never waste time with flaky tests caused by the eventual consistency characteristics of the search engine. This solution will not be presented now but in a future opportunity.

To play with it install Go on your system. You’ll need to connect to a PostgreSQL database. What if there is a powerful domain-specific structured query language designed to manage data out there? $ evans repl -host localhost -port 8082 -r You can check if a connection is working by calling psql. It turns out there is one created almost half a century ago, in 1974: SQL, created by Donald D. Some technical benefits from using PostgreSQL include: Boyce.Ĭonsidering trade-offs, for a typical project, I prefer being able to define sound data structures up-front and having a low cost of maintenance over time, rather than a reduced cost of prototyping promised by “no-SQL” databases.You can use inheritance between tables.You can use JSON types when your requirements are fluid.Custom data types such as enum (to enumerate or restrict values for a given column) and composite (list of attribute names and data types, essentially the same as the row type of a table).MySQL is merely relational and plagued by Oracle’s controversial control over it. In comparison, PostgreSQL is truly community-driven (see The PostgreSQL Global Development Group).
Why not SQLite? SQLite is the most used database engine in the world: from smartphones to jet engines. It also excels in performance, and it has aviation-grade quality and testing. However, it is not a client/server SQL database, and it is trying to solve a different problem.
