    Project mention: Graph Databases vs Relational Databases: What and why? | | 2023-03-29

    First, you need to choose a specific graph database platform to work with, such as Neo4j, OrientDB, JanusGraph, Arangodb or Amazon Neptune. Once you have selected a platform, you can then start working with graph data using the platform's query language.

  • Apache Solr

    Apache Lucene and Solr open-source search software

    Project mention: Tools to use to query and index data? | /r/csMajors | 2023-06-29

  • ObjectBox Java (Kotlin, Android)

    Java and Android Database - fast and lightweight without any ORM

    Project mention: Looking for android java developer mentor | /r/learnprogramming | 2023-05-31

    I would focus on Kotlin instead of Java, there's really no point in sticking to Java at this point. And when it comes to databases, some local ones that are pretty easy to get into are Realm and ObjectBox, SQLite can definitely be a bit overwhelming at the beginning.

    Project mention: Building an efficient sparse keyword index in Python | | 2023-08-17

    First, a review of the landscape. As said in the introduction, there aren't a ton of good options. Apache Lucene is by far the best traditional search index from a speed, performance and functionality standpoint. It's the base for Elasticsearch/OpenSearch and many other projects. But it requires Java.

    Project mention: What Kind of Asynchronous Is Right for You? | | 2023-06-17

    How this article does not mention SSE, comet or chunking escapes me.

    What does their definition of event-driven really look like in practice.

    Nobody has a clue.

    Here is the ideal event driven system, it's async-to-async:

    The example is not working because I had to shut down the services for multiple reasons, but the high level of it is that you use 4 (potentially different) threads to do one request/response middle man transaction.

    That way you have _zero_ io-wait or idling. I'm surprised nobody has copied this approach since I invented it 10 years ago. I understand why though you need your entire chain to be async and that means rewriting everything and that is a big risk when it's hard to debug.

    But if you succeed you can build something that is 10x perf/watt than all other implementations. Which is going to be important when interest rates go higher and crash our entire industry.
