I’ve encountered many conditions up to now the place I needed to get Pub/Sub messages right into a BigQuery desk, however I by no means managed to discover a notably easy approach of doing this.

You possibly can arrange a dataflow pipeline, however this requires further infrastructure to know, configure, handle and debug. Plus Dataflow (which is a managed Apache Beam service) is designed for high-throughput streaming, so at all times appeared like overkill for a easy message logging or monitoring system.

And it’s Java. However Python 😀! And Java… 😫!

Sorry, I nonetheless get flashbacks from my first makes an attempt to study to code (final century) in Java. Please don’t try to make use of that code snippet … step away from the code snippet.

I then stumbled upon this, which — though promising simplicity — appears to be much more sophisticated than the earlier technique (Debezium wtf?)!

It’s additionally doable to deploy a light-weight Cloud Operate to set off on receipt of a Pub/Sub message and stream or load this into BigQuery, however this nonetheless appeared a bit too complicated for one thing which felt prefer it ought to and will have been native performance.

And now it’s!

The type people at Google Cloud announced a direct connection from Pub/Sub to BigQuery some time in the past, superior! Nevertheless, having tried (and failed) to rapidly arrange a check a few occasions, I lastly had a real-life use-case which required me to get it working for a shopper.

It seems that there are a few nuances, so this text goals that will help you get this up and working as rapidly as doable.

Pub/Sub is an extremely helpful, highly effective and scaleable service within the Google Cloud ecosystem, with two core use-cases: streaming…
