Scala with Text Files and ElasticSearch

I seriously don’t know why I keep doing this to myself. I know learning new things I something I need to do, but why Scala? I’m perfectly happy writing Python all day long. It’s straight forward and concise, no boilerplate, no re-inventing the wheel. I’ve written pipelines that crunch hundreds of TBs of data in […]

Intro to Apache Beam for Data Engineers

What is this thing? What’s it good for? Who’s using it and why? That’s pretty much what I ask myself once a month when I actually see the name Apache Beam pop up in some feed I’m scrolling through. I figured it has to be legit to be Apache incubated, but I’ve never run across […]

Pandas DataFrame.to_sql() …. { how you should configure it to not be that guy. }

I never understand it when someone comes up with a great tool, then defaults it to work poorly… leaving the rest up to imagination. The Pandas dataframe has a great and underutilized tool… to_sql() . Lesson learned, always read the fine print I guess. I’m usually guilty of this myself… wondering why something in slow […]

The Battlefield of the Data Engineer.

I want to interrupt your semi-regularly scheduled technical blog post for this public service announcement. I mean the url does say “confessions” does it not? For better or worse I’ve been thinking a lot lately about what it means to be a Data Engineer, what’s like to be a Data Engineer, and what makes a […]

Intro to Apache Kafka for Data Engineers

Streams, streams, streams…. when will it ever end? It’s hard to keep up with all the messaging systems these days. GCP PubSub, AWS SQS, RabbitMQ, blah blah. Of course there is Kafka, hard to miss that name floating around in the interwebs. Since pretty much every system designed these days is a conglomerate of services… […]

Apparently Apache Hive is still a thing…. I should probably learn it.

So what’s up with Apache Hive? It’s been around a long time…but all the sudden it seems like it’s requirement in every other job posting these days. “It’s not you… it’s me.” That’s what I would tell Hive if it suddenly materialized as Mr. Smith via the Matrix that I’m pretty sure is the new […]

Geospatial Data with Apache Spark – Intro to RasterFrames

Yikes, distributed geospatial data processing at scale. That has fun written all over it… not. There isn’t that many people doing it so StackOverflow isn’t that useful. Anyone who has been around geospatial data knows the tools like GDAL are notoriously hard to use and buggy… and that one’s probably the “best.” What to do […]

PySpark SQLContext….tired of your decades old ETL process?

Seriously. Haven’t you had enough of SSIS, SAP Data Services, Informatica, blah blah blah? It’s been the same old ETL process for the last 20 years. CSV files appear somewhere, some poor old aged and angry Developer soul in a cubicle pulls up the same old GUI ETL tool, maps a bunch of columns to […]

Create Your Very Own Apache Spark/Hadoop Cluster….then do something with it?

I’ve never seen so many posts about Apache Spark before, not sure if it’s 3.0, or because the world is burning down. I’ve written about Spark a few times, even 2 years ago, but it still seems to be steadily increasing in popularity, albeit still missing from many companies tech stacks. With the continued rise […]

Learning to do HTTP in Scala. – Part Trois.

Man. Every time I open IntelliJ to write/learn some more Scala I have to take a deep breath. Yes, it’s been fun and good for my to my brain feel like in a Doctor Strange movie, but it’s also challenging and frustrating at times. One of the things I find myself doing a lot as […]
