Keyspaces is a managed, serverless database compatible with Apache Cassandra. Teams running Cassandra workloads get them managed on AWS — scalable and serverless — without operating Cassandra clusters.
The tell
Watch for the word Cassandra or CQL. Keyspaces runs Cassandra-compatible workloads with no servers to manage and automatic scaling. It’s the Cassandra counterpart to how DocumentDB serves MongoDB and MSK serves Kafka.
Test yourself
A company runs Apache Cassandra applications and wants a managed, serverless, Cassandra-compatible database on AWS. Which service?
- Amazon DynamoDB
- Amazon Keyspaces
- Amazon DocumentDB
- Amazon Neptune
👉 Click to reveal the answer & explanation
Correct answer: B. Keyspaces is managed, serverless, and Apache Cassandra-compatible, so Cassandra apps run with minimal change. DynamoDB (A) isn’t Cassandra-compatible; DocumentDB (C) targets MongoDB; Neptune (D) is a graph database.
