Using RavenDB for data aggregation from dynamic sources

Using RavenDB for data aggregation from dynamic sources

March 24, 2022

I got an interesting question from a customer recently and thought that it would make for a fun blog post. The issue the customer is facing is that they are aggregating data from many sources, and they need to make sense of all the data in a nice manner. For some of the sources, they have some idea about the data, but in many cases, the format of…

A tale of eventually consistent ACID model

A tale of eventually consistent ACID model

March 23, 2022

I recently had a conversation about ACID, I don’t think it would surprise anyone that I’m a big proponent of ACID. After all, RavenDB was an ACID database from the first release. When working with distributed systems, on the other hand, it is far harder to get ACID guarantees at a reasonable cost. Pretty much all the 1st generation NoSQL databases…

Using RavenDB from Serverless applications

Using RavenDB from Serverless applications

March 22, 2022

I got a great question about using RavenDB from Serverless applications: DocumentStore should be created as a singleton. For Serverless applications, there are no long-running instances that would be able to satisfy this condition. DocumentStore is listed as being “heavy weight”, which would likely cause issues every time a new insurance is…

Data ownership in a distributed system

Data ownership in a distributed system

March 17, 2022

When you have a distributed system, one of the key issues that you have to deal with is the notion of data ownership. The problem is that it can be a pretty hard issue to explain properly, given the required background material. I recently came up with an explanation for the issue that I think is both clear and shows the problem in a way that…

Full-Text Search Fundamentals in RavenDB

Full-Text Search Fundamentals in RavenDB

March 15, 2022

When it comes to full-text search, years of googling have conditioned us to expect instant, accurate results for any query we can come up with. Unfortunately, creating a powerful and effective search engine is really hard. While most databases offer some kind of search functionality it’s usually bare bones, and the issues of speed and relevancy…

Recording: Database Security in a Hostile World

Recording: Database Security in a Hostile World

March 14, 2022

The internet is a hostile place. Publicly accessible machines will be attacked within minutes of being connected, and any unencrypted data in transit is likely to be intercepted and modified. Every day there are successful attacks on applications and databases that are insufficiently protected, resulting in data leaks and ransom demands. In this…

Defense in depth and the local server

Defense in depth and the local server

March 11, 2022

Yesterday I gave a webinar about Database Security in a Hostile World and I got a really interesting question at the end: If your RavenDB and app are on the same server, would you recommend using certificates? The premise of the talk was that you should always run in a secured mode, even if you are running on a supposedly secured network. That…
