Now we get to the significantly more disruptive stuff. The things that while Tigris is an S3-compatible API it also provides features that enable entirely new use-cases and push the boundaries of what you can do with object storage. Let's see if we can't set your internal constraint-solver aflame with possibilities.

Early returns is often employed to exit a function as soon as an exceptional or negative condition is met. It won't take much time when learning elixir to figure out that early returns are missing!

Let’s say that you’ve been following the latest research in key/value data storage and are interested in managing such data in a PostgreSQL database. You want to have functions to store and retrieve pairs, but there is no natural way to represent pairs in SQL. Many languages have hashes or or data dictionaries to fulfill this role, and you can pass them to functional interfaces. SQL’s got nothin’. In PostgreSQL, have two options: use nested arrays (simple, fast) or use a custom composite data type (sugary, legible).

With the array, PostgreSQL allows columns of a table to be defined as variable-length multidimensional arrays.
