Rockset vs Zerto
Side-by-side comparison of AI visibility scores, market position, and capabilities
Rockset is a real-time analytics database enabling sub-second SQL queries on streaming and operational data, acquired by OpenAI in 2024 to power its infrastructure.
About
Rockset is a real-time analytics database company founded in 2016 by Facebook engineering veterans that built a cloud-native database optimized for sub-second SQL queries on live streaming and operational data. The platform enables developers and data engineers to run complex analytical queries on data that is continuously ingested from sources including Kafka, DynamoDB, S3, and MongoDB without the latency of traditional batch ETL pipelines. Rockset's Converged Index technology pre-processes and indexes all fields in ingested data automatically, enabling fast queries without requiring users to define schemas or indexes upfront. The company raised $105M and served hundreds of customers building real-time analytics features including personalization, fraud detection, and operational dashboards. In 2024, OpenAI acquired Rockset to power the retrieval infrastructure underlying its AI products, recognizing the need for fast vector and structured data search at the scale of OpenAI's user base. The acquisition validated Rockset's technology for demanding real-time search and analytics workloads and brought the team and infrastructure into OpenAI's engineering organization.
Zerto delivers continuous data protection and disaster recovery for virtualized and cloud workloads, enabling near-zero RPO recovery as a Hewlett Packard Enterprise product.
About
Zerto is a continuous data protection and disaster recovery platform that uses journal-based replication to capture every write operation to protected virtual machines and cloud workloads, maintaining a rolling recovery journal that enables point-in-time recovery to any second within the journal window rather than only to the most recent backup snapshot. This approach collapses the recovery point objective for protected workloads to near-zero — seconds rather than hours — fundamentally changing the data protection economics for organizations whose business-critical applications cannot tolerate the data loss that snapshot-based backup schedules produce. The platform's continuous replication engine operates at the hypervisor level without agents in protected VMs, capturing changes with minimal performance impact while maintaining the journal that enables granular recovery point selection.
