How does ScyllaDB compare to Amazon Keyspaces?

ScyllaDB is a C++ rewrite of Cassandra achieving dramatically higher throughput with shard-per-core architecture and lower p99 latencies. Keyspaces is serverless, eliminating cluster management. ScyllaDB Cloud provides managed deployment with ScyllaDB's performance advantages. For high-throughput workloads where cost per operation matters, ScyllaDB typically wins; for operational simplicity, Keyspaces wins.

Is DataStax Astra DB a better managed Cassandra than Amazon Keyspaces?

Astra DB runs on true Apache Cassandra, providing full CQL compatibility including newer Cassandra 4.x features that Keyspaces lacks. It also offers Document, GraphQL, and REST APIs beyond CQL. Astra DB runs on AWS, GCP, and Azure. Keyspaces benefits from deep AWS IAM integration and VPC networking. For Cassandra feature completeness, Astra DB leads.

When should I use Google Bigtable instead of Amazon Keyspaces?

Choose Bigtable when workloads are GCP-native, when you need a true wide-column store optimized for time series and analytical scans (not Cassandra CQL workloads), when integrating with BigQuery or Dataflow, or when managing petabyte-scale datasets. Keyspaces and Cassandra are better for CQL-based application patterns; Bigtable serves different use cases closer to HBase workloads.
