| Replication | Cross-Datacenter Replication provides asynchronous active-active replication between clusters, while synchronous active-active supports strongly consistent global transactions. | RonDB supports synchronous cross-availability-zone active-active replication with 1 to 3 replicas and asynchronous cross-region replication across clusters with conflict resolution. |
| Transactions | Aerospike 8 provides strict serializability guarantees for distributed ACID transactions. | RonDB is ACID compliant through MySQL-server support, with in-memory data persisted using REDO logs and checkpoints. |
| What it does | Aerospike Database is a distributed NoSQL platform for real-time workloads requiring predictable low latency, high availability and very large scale. | RonDB is a distributed, shared-nothing storage engine and an open-source fork of MySQL NDB Cluster for real-time applications. |

RonDB
RonDB is an open-source distributed storage engine for real-time applications and a fork of MySQL NDB Cluster. Its shared-nothing design supports up to 1 PiB of storage, with online horizontal and vertical scaling for storage and MySQL-server compute. Applications can use the MySQL Server API for SQL-compatible access and parallel queries. ACID transactions are provided through MySQL-server support; in-memory data is persisted using REDO logs and checkpoints.
RonDB describes its performance aims as low latency, high availability, high throughput, and scalable storage. It supports AI application storage integrated with Spark and Kafka, while Rondis implements a Redis server using RonDB storage and the Redis wire protocol. Deployment options include local testing, Docker, cloud deployments using your own AWS, Azure, or GCP credentials, and on-premises deployment by inquiry. Replication can be synchronous active-active across availability zones or asynchronous across regions with conflict resolution. RonDB is used as the online feature-store database for machine-learning applications in Hopsworks. The serverless plan through Hopsworks is free, with quotas on Feature Groups and memory usage.
