The article Bring analytics to your data: What’s new with BigQuery federated queries that I'm co-author of was published on Google Blog so I'm happy to share it. From the article you will learn about new interesting features in BQ federation area like SQL Pushdown or Private IP Access. I had an opportunity (and not only me) to have my hands in some of these features so I'm happy to see them officially announced. Especially excited I'm about SQL Pushdowns. This was a challenging but also very interesting task which allow me to learn a lot about internals of a database engine. *The picture ..read more

Ethereum network and manipulations

In cooperation with Nethermind, I published another research on EIP-1559.  If you don't remember or don't know it, EIP-1559 is an improvement that replaces the auction-based fee market in Ethereum network with a basefee and a tip. The difference between the basefee and the tip is that the first one is paid by a user and burned by the protocol, and the tip is paid directly to the miner. This time I focus on the possibility of the basefee manipulation. As everywhere where the money is involved, somebody can try to cheat the system. You can find the article here ..read more

Neo4j Cypher is great but sometimes strange

My journey with Neo4j started a few months ago and I really think that it is a great database and I'm in love with its query language called Cypher. However, especially having SQL background some things might be surprising (in this negative way). I will give you an example. Let's assume that we have a graph that among other store movies. We may write such a query to retrieve all the movies: MATCH (m:Movie) RETURN m Here is a sample result: If we slightly modify this query we can select movies that were released in 1999: MATCH (m:Movie) WHERE m.released = 1999 RETURN m This time w ..read more

Event Storming workshops from the other side

Some time ago I gave the presentation about DDD and Event Storming during Girls Do IT 2019 conference. I also had occasion to run workshops on the same topic during Programistok 2018 and facilitated a few Event Storming sessions in the past (here is one example). So I can say that I have experience with this very nice modeling and business domain exploration technique proposed by Alberto Brandolini. However, when I realized that I can take part in Event Storming Workshops organized by Krzysztof Owsiany and Mikołaj Jakubowski I didn't hesitate much to sign in. The workshops had two p ..read more
