5. Pick of the Week
This week, we’re looking at Cassandra – the battle-tested database that’s the backbone of sites with incredible amounts of traffic, like Facebook and Netflix:
For a long time, the “getting started” story in Cassandra was a bit slow, as there was simply no direct API support. That’s been changing recently on the Astra Cloud:
We now have several ways to interact with Cassandra beyond the standard CQL – direct data access via REST, a powerful document API working with schemaless JSON, as well as GraphQL APIs.
Definitely have a look at Astra with their free-forever 5 Gig tier, which is pretty useful to actually use the system and understand what it can do.
