Selecting Representative Samples From A Stream Of Queries
+0 Vote Up -0Vote Down

Sampling is hard. This is the title of a talk I gave at a meetup in Boston a few weeks back. But what’s so hard about sampling anyway?

To begin with, let’s clarify what I mean by sampling. It’s a bit ambiguous because sampling could apply to a few different things one does with time series data. In this context, I’ll be talking about capturing individual events from a large, diverse set of events (queries).

It was a very long time since I wrote something in this blob, but I have been very busy this spring with MariaDB on Power. This has been a lot of work, but also a lot of fun. So, what is this MariaDB on Power thing all about, well I wrote an introduction to the Power platform late last year. Since then a lot of things has happened.
