Building a flexible, realtime data warehouse at Sentry with Beam + Dataflow (Syd Ryan)

Syd Ryan describes two hard problems they've solved at Sentry with streaming Beam pipelines. The first solution combines Postgres change data capture and SQL views to produce a table that appears to be updating in real time within BigQuery. The second solution is aggregating 1000s of events per second and backfilling historical data effectively with Beam's unified batch/streaming interfaces.

Beam in Production: Lessons learned and best practices (Mike Clarke)

Mike describes gotchas and early struggles Sentry hit moving streaming data pipelines off our laptops and into production. He covers some unexpected Beam defaults, detecting schema errors, compare performance between the python & java SDK, and proactively identifying when production pipelines break due to unexpected data.

Performance Tuning a Rails App With AppOptics Dev Edition

The other day I found myself trying to tune a Ruby on Rails app I had written as a side project. (The app lets me keep track of my favorite eateries and pubs. It’s searchable, includes multiple images, and has stored locations.) On past projects, I relied on SolarWinds® Papertrail™, path testing, a lot of trial and error, and a general feel to try to improve performance. This time I thought I would give SolarWinds AppOptics™ Dev Edition a try.

Self-Driving Anomaly Detection

Imagine driving on the freeway in a (partially) self-driving car like a Tesla. While you drive the car, you come across things you would expect like trees, lampposts and other cars but also things that don't belong there like trash floating around. Meanwhile, radars and sensors in the car are working hard to make sure you don't crash because of these things. If you see the freeway as your fast-changing IT environment, then all the things that don't belong there are anomalies.

Benchmarking web performance: An actionable guide using Real User Monitoring

Customer experience is becoming a key differentiator between competitors. Actually, it already is! If your website is performing poorly, it’s hurting your business. The first step towards improving this performance is using a real user monitoring tool to identify problems and monitor your progress towards improvement.

An Inside Look at the Life of a Technical Writer at Grafana Labs

People think technical writing is boring, but sometimes documenting software is an adventure. It’s not an adventure like “whee, got my sword and shield, adventure time!” No, it’s more like taking a nice stroll down a path to an unfamiliar-but-known destination when the ground suddenly opens up under your feet. As you’re falling down into the depths, that’s when you realize you are about to have an adventure. I’m a technical writer at Grafana Labs.
