8 Best CockroachDB Alternatives & Competitors (2026)

Redshift is AWS's managed data warehouse with strong integration into the Amazon ecosystem. It supports large-scale analytics and recently added more real-time features, yet generally requires separate systems for low-latency transactions unlike SingleStore's single engine. Cost and concurrency behavior differ noticeably at petabyte scale.

Databricks unifies data lakes, analytics, and machine learning on Apache Spark foundations. It provides excellent AI and vector capabilities plus lakehouse architecture, yet typically involves more setup than SingleStore for low-latency SQL serving. Teams needing both heavy ETL and real-time queries often compare its total cost and operational complexity directly against SingleStore.

ClickHouse is an open-source columnar database optimized for fast analytical queries on large datasets. It delivers exceptional OLAP speed and can handle high ingest rates, but lacks SingleStore's native transactional guarantees and built-in AI functions. Many users choose it when pure analytics performance matters more than unified OLTP plus vector search.

BigQuery is a serverless analytics warehouse known for ease of use and automatic scaling. It excels at ad-hoc SQL on massive datasets but is not designed for mixed transactional workloads or ultra-low latency serving that SingleStore targets. Pricing is usage-based and attractive for intermittent analytics.

MongoDB is a document database popular for flexible JSON workloads and developer velocity. It now includes vector search and analytics capabilities, yet remains weaker than SingleStore on complex analytical SQL performance and high-concurrency mixed workloads at enterprise scale.

TiDB is an open-source distributed SQL database that separates storage and compute for HTAP use cases. It offers good scalability and MySQL compatibility but generally provides less mature real-time analytics and AI function integration than SingleStore's purpose-built engine.
