The Problem

The documentation for how to deploy a pipeline with extra, non-PyPi, pure Python packages on GCP is missing some detail. This gist shows how to package and deploy an external pure-Python, non-PyPi dependency to a managed dataflow pipeline on GCP.

TL;DR: You external package needs to be a python (source/binary) distro properly packaged and shipped alongside your pipeline. It is not enough to only specify a tar file with a setup.py.

Preparing the External Package

Your external package must have a proper setup.py. What follow is an example setup.py for our ETL package. This is used to package version 1.1.1 of the etl library. The library requires 3 native PyPi packages to run. These are specified in the install_requires field. This package also ships with custom external JSON data, declared in the package_data section. Last, the setuptools.find_packages function searches for all available packages and returns that

 * A common use of a disjunction is to explicitly represent the possibility of failure in a result
 * as opposed to throwing an exception (that is a side effect).
 *
 * `A` [[\/]] `B` is isomorphic to `scala.Either[A, B]`, but [[\/]] is right-biased, so methods such

-- Our goal is to create a type describing a list of events. This is our
-- type-level DSL.
-- We will then use typeclass resolution to "interpret" this type-level DSL
-- into two things:
-- 1. A comma-separated list of events
-- 2. A method that, when given an event name and a payload, will try to parse
--    that event type with the payload. A form of dynamic dispatching

-- To model a list of types we will use tuples. You can imagine the list of
-- types "Int, String, Char" to look like:

TL;DR

Create a backup:

pg_dumpall > mybackup.sql

Perform the upgrade:

sudo pg_dropcluster 9.4 main --stop
