This is a introductory overview of JSONB for those who have not had the pleasure of using it before.

What I will try to cover:

  • A quick overview of the syntax basics as well as how we use JSONB in our clinical healthcare app, where we capture largely unstructured clinical data.
  • What do you want to use it for, and what is it bad for.
  • The different indexes on JSONB and what they are generally good for.
  • How to create custom datatypes on top of JSONB.
  • Doing partial (sub structure) updates.
  • Creating JSONB structure from current tables with jsonb build object, to jsonb and jsonb agg.
