What tool do you use for diagrams?

The diagrams here: Announcing Kafka Connect: Building large-scale low-latency data pipelines | Confluent | UK

and here: Choose Your Own Topology, A Kafka Streams Adventure with Anna McDonald | Saint Louis Apache Kafka® Meetup by Confluent?

look very nice, what tool do you all use to produce them?

I asked around and there’s a mix of tools in play on the Confluent blog / Confluent Developer based on personal preferences:

  • Lucidchart. This was used in the Streams Meetup drawings, also some hand drawn
  • Excalidraw
  • Concepts. I’m not positive that the Connect blog used this but it seems like it.

Excellent source information for learning.
