Our review
Pros	Replicates data across datacenters with tunable consistency levels Scales horizontally by adding nodes Offers CQL, lightweight transactions, snapshots, and incremental backups	Raft replication supports strong consistency and leader election. Transactions, watches, and TTL leases suit coordination workloads. Snapshots, recovery, and TLS support cluster operations and security.
Cons	Requires self-managed deployment Community and documentation are the listed support channels Wide-column data model may not suit workloads needing another database model	Its focus is key-value coordination, not a broad distributed platform. Self-hosted deployment means teams manage the binaries or containers. Its API options center on gRPC and HTTP/JSON.
Our verdict	Apache Cassandra is an open-source, distributed NoSQL database built around a partitioned wide-column data model. It is aimed at teams managing large datasets and high-volume reads and writes across distributed deployments. The product is… Read the review →	etcd provides strongly consistent distributed key-value storage for distributed systems and clusters of machines.
