Honeybee Swarms I love honeybees. This will be my seventh year as an amateur beekeeper, and aside from family or data, there are few other topics that I could easily spend an afternoon talking to you about. They’re amazing creatures. This past winter I had to move my beehives temporarily to the apiary of a friend. With the warmer winter, all four hives came through winter and are stronger than ever. (for reference, in recent years it’s typical to lose 50% of your hives over the winter.) But here’s the thing with strong healthy hives. They swarm! The queen bee decides that the hive has too many bees and prepares to leave, taking approximately half of the hive with her. She leaves behind a handful of unhatched queens, one of which will take over the hive in a few days. As a beekeeper this is a good thing, if you can catch the swarm (or five, as the case may have been for me the past 10 days). It means that you (or a friend if you can’t keep it) get an extra hive for free. On the other hand, when the swarm totally absconds, it feels like a loss of free bees… and extra honey later in the season. Regardless, every time a hive swarms I’m reminded that a healthy hive is doing exactly what it’s supposed to. Each hive has one queen bee, and the entire hive is there to serve and protect her, because she’s the one that lays the eggs to grow the hive. She exists for one purpose, to produce more bees, to form more hives, to keep forming more bees. The pollination and honey are a wonderful (and necessary) byproduct of that main purpose. After all, bees pollinate 80% of all flowering plants, so we need more of them. How can you tell when things around you are healthy and “firing on all cylinders?” What’s one thing that is working just right, doing exactly what it was intended to do? As you look around this summer (for those of us in the northern hemisphere) and see bees coming and going, I hope it reminds you about healthy hives and fulfilled purpose. Not just for the bees, but for you, too. Ryan Booz Join the debate, and respond to the editorial on the forums |
The Weekly News | All the headlines and interesting SQL Server information that we've collected over the past week, and sometimes even a few repeats if we think they fit. |
IAsyncEnumerable is a powerful interface introduced in C# 8.0 that allows you to work with sequences of data asynchronously. It is a great fit for building ETLs that asynchronously stream data to get it ready for transfer. You can think of IAsyncEnumerable as the asynchronous counterpart of IEnumerable because both interfaces allow you to easily iterate through elements in a collection. Since the early days of .NET, the IEnumerable interface has been fundamental for many programs. The IEnumerable interface provided a way to retrieve elements from a collection one at a time, and the IEnumerable interface extended this functionality to generic types. However, the IEnumerable interface is synchronous, which means that it is not suitable for working with asynchronous data sources. |

When dealing with the development, testing and releasing of new versions of an existing production database, developers like to use their existing production data. In doing so, the development team will be hit with the difficulties of managing and accommodating the large amount of storage used by a typical production database. It’s not a new problem because the practical storage capacity has grown over the years in line with our ingenuity in finding ways of using it. To deal with using production data for testing, we generally want to reduce its size by extracting a subset of the entities from a ‘production’ database, anonymized and with referential integrity intact. We then deliver this subset to the various development environments. |

The first two articles in this series demonstrated how PostgreSQL is a capable tool for ELT – taking raw input and transforming it into usable data for querying and analyzing. We used sample data from the Advent of Code 2023 to demonstrate some of the ELT techniques in PostgreSQL. In the first article, we discussed functions and features of SQL in PostgreSQL that can be used together to transform and analyze data. In the second article, we introduced Common Table Expressions (CTE) as a method to build a transformation query one step at a time to improve readability and debugging. In this final article, I’ll tackle one last feature of SQL that allows us to process data in a loop, referencing previous iterations to perform complex calculations: Recursive CTE’s. |

The Baseline command is intended to make it easy to turn any preexisting production database into a Flyway database so that, subsequently, versioned migrations can then be applied to it, bringing greater stability and predictability to database deployments. Unlike most databases in development, a ‘Flyway database’ will be at a known version, with a record of the migration files used to get to that version. However, what if you want to adopt Flyway versioning with an existing database that is already in use? |
