List of the Top 5 On-Prem Query Engines in 2025

StarTree Cloud functions as a fully-managed platform for real-time analytics, optimized for online analytical processing (OLAP) with exceptional speed and scalability tailored for user-facing applications. Leveraging the capabilities of Apache Pinot, it offers enterprise-level reliability along with advanced features such as tiered storage, scalable upserts, and a variety of additional indexes and connectors. The platform seamlessly integrates with transactional databases and event streaming technologies, enabling the ingestion of millions of events per second while indexing them for rapid query performance. Available on popular public clouds or for private SaaS deployment, StarTree Cloud caters to diverse organizational needs. Included within StarTree Cloud is the StarTree Data Manager, which facilitates the ingestion of data from both real-time sources—such as Amazon Kinesis, Apache Kafka, Apache Pulsar, or Redpanda—and batch data sources like Snowflake, Delta Lake, Google BigQuery, or object storage solutions like Amazon S3, Apache Flink, Apache Hadoop, and Apache Spark. Moreover, the system is enhanced by StarTree ThirdEye, an anomaly detection feature that monitors vital business metrics, sends alerts, and supports real-time root-cause analysis, ensuring that organizations can respond swiftly to any emerging issues. This comprehensive suite of tools not only streamlines data management but also empowers organizations to maintain optimal performance and make informed decisions based on their analytics.

ClickHouse is a highly efficient, open-source OLAP database management system that is specifically engineered for rapid data processing. Its unique column-oriented design allows users to generate analytical reports through real-time SQL queries with ease. In comparison to other column-oriented databases, ClickHouse demonstrates superior performance capabilities. This system can efficiently manage hundreds of millions to over a billion rows and can process tens of gigabytes of data per second on a single server. By optimizing hardware utilization, ClickHouse guarantees swift query execution. For individual queries, its maximum processing ability can surpass 2 terabytes per second, focusing solely on the relevant columns after decompression. When deployed in a distributed setup, read operations are seamlessly optimized across various replicas to reduce latency effectively. Furthermore, ClickHouse incorporates multi-master asynchronous replication, which supports deployment across multiple data centers. Each node functions independently, thus preventing any single points of failure and significantly improving overall system reliability. This robust architecture not only allows organizations to sustain high availability but also ensures consistent performance, even when faced with substantial workloads, making it an ideal choice for businesses with demanding data requirements.

PuppyGraph enables users to seamlessly query one or more data sources through an integrated graph model. Unlike traditional graph databases, which can be expensive, require significant setup time, and demand a specialized team for upkeep, PuppyGraph streamlines the process. Many conventional systems can take hours to run multi-hop queries and struggle with managing datasets exceeding 100GB. Utilizing a separate graph database can complicate your architecture due to fragile ETL processes, which can ultimately raise the total cost of ownership (TCO). PuppyGraph, however, allows you to connect to any data source, irrespective of its location, facilitating cross-cloud and cross-region graph analytics without the need for cumbersome ETLs or data duplication. By directly integrating with your data warehouses and lakes, PuppyGraph empowers you to query your data as a graph while eliminating the hassle of building and maintaining extensive ETL pipelines commonly associated with traditional graph configurations. You can say goodbye to the delays in data access and the unreliability of ETL operations. Furthermore, PuppyGraph addresses scalability issues linked to graphs by separating computation from storage, which enhances efficient data management. Overall, this innovative solution not only boosts performance but also simplifies your overall data strategy, making it a valuable asset for any organization.

Ensure that crashes of games, applications, or devices don't hinder your enjoyable experience. Backtrace streamlines the management of exceptions and crashes across various platforms, allowing you to concentrate on delivering your product. It provides a unified call stack, event aggregation, and comprehensive monitoring solutions. This single system efficiently handles errors from panics, core dumps, minidumps, and runtime issues across your entire stack. Backtrace creates structured and searchable error reports from your collected data. Its automated analysis significantly shortens the resolution time by highlighting critical signals that guide engineers to the root cause of crashes. With seamless integrations into various dashboards and notification systems, you can rest assured that no detail will slip through the cracks. The advanced queries engine offered by Backtrace empowers you to address your most pressing questions. A broad overview of errors, along with prioritization and trends spanning all your projects, is readily accessible. Furthermore, you can sift through essential data points and your customized information for every error, enhancing your overall troubleshooting process. This comprehensive approach ultimately leads to a more efficient workflow and improved product reliability.

Starburst enables organizations to strengthen their decision-making processes by granting quick access to all their data without the complications associated with transferring or duplicating it.
