Interesting Stuff - Week 40, 2020

Posted by nielsb on Sunday, October 4, 2020

Throughout the week, I read a lot of blog-posts, articles, and so forth, that has to do with things that interest me:

  • data science
  • data in general
  • distributed computing
  • SQL Server
  • transactions (both db as well as non db)
  • and other “stuff”

This blog-post is the “roundup” of the things that have been most interesting to me, for the week just ending.

Big Data

  • Diving Into Delta Lake: DML Internals (Update, Delete, Merge). Later releases of Delta Lake supports DML, (data manipulation language), statements. The post linked to here demonstrates how to use each of these DML commands, describes what Delta Lake is doing behind the scenes when you run one, and offers some performance tuning tips for each one. Very cool!


WIND (What Is Niels Doing)

Yes, what AM I doing? Sometimes, quite often actually, I wonder that myself. Today, however, I do know what I am doing, or more specifically, what I just did! Yesterday, (October 3), I delivered a virtual conference talk at SQLBits about SQL Server and Kafka.

Unfortunately, the talk was pre-recorded, and after I had uploaded the recording, the organizers did some editing. I messed up with what parts of the talk needed editing, so the result was that around a third of the talk was missing. Not good! Anyway, the organizers will do a re-edit and upload so that attendees can view it on demand. If you were one of the attendees, I do apologize again!

Anyway, today I uploaded the slide deck as well as all code for the talk, (including instructions). If you are interested, you can download it from here. If you have questions comments etc., please ping me.

That’s all for this week. I hope you enjoy what I did put together. If you have ideas for what to cover, please comment on this post or ping me.
