"Cassandra has the Monopoly on ACID Transactions"

Great watch for a hands-on introduction to Accord Transactions.
Over the past 12 months Apache Cassandra is the 5th fastest growing database, according to db-engine trends.
Amongst just the operational/transactional databases, the 3rd.
We can't wait til 6.0 goes GA with Accord (ACID) Transactions and Transactional Cluster Metadata (TCM).
Check out @soheilrahsaz.bsky.social post:
Building a RAG app with Crypto News, Cassandra and Spring AI.
🔍 Highlights:
✅ Scalability in storing and retrieving embeddings efficiently
✅ Spring AI for natural language interaction
✅ GenAI application just open-source tools
