How to support unstructured data in Postgres with JSON columns

JSON and JSONB type allows you to store unstructured data in Postgres. In this video, Tyler Shukert walks you through how to store and query JSON data from your Postgres database.

Postgres is a relational database, but it also has support for JSON and JSONB-type columns, which allows developers to store unstructured data. Not only can they be flexible with the data to be stored, but there are many unique operators for querying JSON data flexibly. We take a deeper look into what the possibilities are with JSON columns on Postgres.

JSON columns in Postgres are so useful, but so are other data types. What is the next data type that you want us to go deep on? Let us know in the comment below 👇

[@user-df1zf9ti2w]

Clear explanation, appropriate examples, looking forward to an example explaining the use of JSONB in a chat session application.

[@Jebusankel]

Where I think supabase really shines is using postgres json functions like json_agg() and row_to_json() to create nested structures.

[@EnesKab]

A great use case for JSON in the SQL database can be a column which stores set of settings for something like custom styles. Let's say you have 3 styles that your user can customize and you want to store them in the database. For example, custom background color, font-size and font-weight. You can create a JSON object to store all these settings without having to create columns for each in a new table and create a relationship between the user. Also, if you create a JSON object for your user's settings, you can manipulate it way easier, add new styles in the future even if they are 20 more and do not need to worry about the performance, and best of all 👉🏻 All is possible without creating a mess in your db.

[@dshukertjr]

User preferences are a great use case for using JSONB columns!

[@xberna8156]

Nice explanation, thank you!

[@dshukertjr]

Glad to hear you found it helpful!

[@planetmall2]

This was awesome!

[@jaany]

Great video!

[@cariyaputta]

Thanks.

[@vengateshm2122]

Seems we can wrap no sql into sql world.

[@Supabase]

Best of both ❤️

How would performance impact the search and database writing when using jsonb vs regular columns?

[@Supabase]

With proper indexes, the difference in speed of querying data from a joined table and jsonb column are negligible. Writing is the same, generally the performance difference should be negligible. You should choose whether to use JSONB or not depending on wha tthe data could look like. If you want to be a bit more flexible with the schema of the data, you can choose to use JSONB.

[@jonathangamble]

can you fo joins?

[@dshukertjr]

Yes, you can join a table with another table using JSON values too!

Is it just me or does the voice sound AI generated?

[@dshukertjr]

I swear nothing was AI generated 😂 Maybe the bad sound quality at the intro and outro are making you feel that way. I will try to improve it on the next recording!

[@indiechatofficial]

@@dshukertjr The sound quality is really good. I think he just means your voice is so peaceful and well-measured that it seems as if an A.I. super intelligence is responsible for it.

[@tylershukert3621]

@@indiechatofficial That is so sweet of you!
