stupid question: you want to build a serverless system where I can host my Elixir functions?

On the non overlapping topic… You could use range as mentionned by other
Here is an example
def change do
execute "CREATE EXTENSION btree_gist", "DROP btree_gist"
create table(:examples) do
add :any, :string
# Using a tstzrange should allow exclusion constraint.
# https://www.postgresql.org/docs/13/rangetypes.html#RANGETYPES-CONSTRAINT
add :period, :tstzrange
timestamps(type: :utc_datetime)
end
# Create a custom constraint enforcing period do not overlap for the same resource.
# This request btree_gist extension!
# https://hexdocs.pm/ecto_sql/Ecto.Migration.html#constraint/3
create constraint(:examples, :no_overlap,
exclude: ~s|gist ("any" WITH =, tstzrange("period") WITH &&)|)
end
This use another field for non-overlapping.
Then You can check the constraint in the schema
...
|> check_constraint(:period, name: :no_overlap, message: "Any overlap in schedule")

@slouchpie flagging this for our use. We may need this to prevent a player from playing in two matches at the same time

I haven’t looked at things like AWS Lambda in a long time, but I feel like they’ve gotten to the point of being able to just run Docker images. Seems like you could make an image with an Elixir release and entrypoint that takes args specifying which function you want to run.
Oh wow, TIL! Really interesting.
I thought Broadway was more about making complex job topologies similar to Apache Spark. With things like multiple datasources and even infinitely running datasources.

I think of it more as a reliable pipeline with back pressure. Doesn’t have to be complex but oftentimes infinite, in my experience.

It is, but at the same time it’s a job system designed for optimizing throughput and you can feed it with something like SQS.
