Amazon Keyspaces Adds Logged Batches for Atomic Writes

🔒 Amazon Keyspaces (for Apache Cassandra) now supports Logged Batches, enabling multiple INSERT, UPDATE, and DELETE operations to be executed as a single atomic transaction. This ensures that all writes in a batch succeed or none are applied, improving consistency across rows and tables for use cases such as finance, inventory, and multi-entity profile updates. The feature preserves Cassandra's atomicity guarantees, integrates with CQL, scales serverlessly with your workload, and is available today in all AWS Commercial and AWS GovCloud (US) Regions. Customers pay only for the standard write operations processed within each batch.

Keyspaces Multi-Region Replication: Bahrain and Hong Kong

🔁Amazon Web Services has expanded Amazon Keyspaces (for Apache Cassandra) to support Multi-Region Replication in Middle East (Bahrain) and Asia Pacific (Hong Kong). The managed capability automatically replicates tables across Regions with typically less than one second of replication lag, allowing applications to read and write the same table in multiple Regions. Customers gain lower latency, improved regional resiliency, and can replicate between these Regions and any other supported AWS Region while paying only for resources they use.

Amazon Keyspaces supports now(), uuid(), and Duration types

🔧 Amazon Keyspaces (for Apache Cassandra) now supports the now() and uuid() functions in SELECT clauses, extending prior support in WHERE, INSERT, and UPDATE. It also introduces a native Duration data type to represent elapsed time between timestamps, removing the need to store intervals as strings or bytes. These updates improve Apache Cassandra compatibility and simplify time-based operations and identifier generation across AWS Commercial and GovCloud regions.
