[Announcement] Memgraph 2.1 - Apache Pulsar & Redpanda welcome! 🚀

Announcing Memgraph 2.1 image

A couple of weeks passed after our big 2.0 launch, but we didn’t stop adding new features to Memgraph. For this Memgraph 2.1 release, we focused on providing you with more options for ingesting your data into Memgraph, and we also enhanced the already existing methods. These are some of the release key points:

  • Apache Pulsar & Redpanda are now available as new data sources,
  • you have even more control over your Apache Kafka streams,
  • support for Bolt v4.3.

Head of Core Antonio wrote the announcement and covered a lot of details about the new release.

Read more about it in the announcement.

A couple of days after the launch, we organised a Memgraph 2.1 live demo. No worries if you missed it live because the recording is available on our YouTube channel.

The demonstration was hosted by CEO Dominik & CTO Buda, founders of Memgraph. Ivan from DevRel team joined them.

Timestamps:

  • [3:35] More about Memgraph 2.1 features like support for Apache Pulsar, Redpanda and Apache Kafka.
  • [36:09] New features in action demonstrated as a graph e-commerce recommender system.
  • [1:07:53] Info about the Memgraph App Challenge - an online graph hackathon where you can compete for the $3500 prize pool.

Also, our viewers had some intriguing questions:

  • [27:44] How can I know if some error happened while I stream my data?
  • [33:49] Which data formats are supported for data import using streams?
  • [59:41] What’s better, Kafka or Pulsar?
  • [1:05:10] Do you have any incremental algorithms for analysing the streaming data?

[Article] Setting the offset with librdkafka isn’t as easy as you’d expect 💡

Chasing messages and offsets in the land of librdkafka

So, what is librdkafka, and how does it handle offsets? Librdkafka is a C client with C++ wrappers that implements the Kafka protocol, and offset management for consumers is done automatically unless configured otherwise. This means that for manual offset management, each time Memgraph processes a Kafka message successfully, it must instruct librdkafka to commit that offset.

Read more about what Kostas from the Core Engineering team learned by implementing offset management for Apache Kafka consumers.

[Tutorial] How to implement a real-time movie recommender with Redpanda & Memgraph?

Tutorial: How to implement a real-time movie recommender with Redpanda & Memgraph

Alongside live demo, Ivan from the DevRel team was also responsible for tutorial how to analyze streaming data with Redpanda.

This tutorial focuses on processing real-time movie ratings streamed through Redpanda, a Kafka-compatible event streaming platform. This data can be used to generate movie recommendations with the help of a graph database and the Cypher query language.

Learn more about it on our blog.

[Tutorial] Connect to a Pulsar Cluster and Analyze Streaming NFT Data with Memgraph

Tutorial: Connect to a Pulsar Cluster and Analyze Streaming NFT Data with Memgraph

Since we have a tutorial with Redpand, Katarina from the DevRel team decided it would be right to make one with Pulsar as well. In this tutorial, you’ll learn how to create a graph schema from the Art Blocks dataset (Ethereum based NFT platform), stream your data with Apache Pulsar and Memgraph, and how to analyse your streaming data.

Apache Pulsar vs Apache Kafka - How to choose a data streaming platform

Apache Pulsar vs Apache Kafka - How to choose a data streaming platform

While Apache Kafka may be the most popular solution for data streaming needs, Apache Pulsar has picked up a lot of popularity in recent years. While both have their pros and cons, there are specific use cases that fit each product better, but it seems that Kafka has become the de-facto solution for most problems, given its popularity. We will try to provide you with a high-level overview of their similarities and differences so you can make a more informed and clear choice.
