Starrocks
StarRocks is a distributed SQL OLAP database engine designed for real-time analytics and high-performance multi-dimensional analysis. It functions as a data lakehouse query engine that enables SQL execution across large datasets and external open table formats without requiring local data imports.
The system employs a shared-nothing distributed architecture and utilizes the MySQL protocol to integrate with business intelligence tools. It maintains real-time data consistency through a primary key upsert model and accelerates query response times using vectorized execution and cost-based optimization.
Broad capabilities include the use of automated materialized views to reduce scan volumes and multi-tenant resource isolation to manage CPU and memory quotas across concurrent workloads. The engine also supports automatic resource balancing and data recovery during cluster scaling.
Features
- Real-Time Analytics - Provides a low-latency real-time analytics engine for processing streaming data and updating business dashboards.
- Cloud Data Lake Integrations - Enables direct SQL access to data stored in open table formats within cloud-native data lakes.
- Data Upsert Operations - Ensures real-time data consistency using a primary key upsert model to update records during ingestion.
- Distributed SQL Databases - Implements a distributed SQL database architecture that scales horizontally while maintaining data availability.
- Federated Data Query Engines - Functions as a federated query engine that accesses remote lakehouse storage formats without requiring local data imports.
- Lakehouse Engines - Acts as an analytics engine capable of querying external data lakes and open table formats without local imports.
- Multi-Dimensional Analysis - Performs complex aggregations and ad-hoc queries across large datasets using vectorized processing.
- OLAP Database Engines - Provides a distributed database designed for high-performance multi-dimensional analytics and sub-second SQL queries.
- Cost-Based Optimizers - Implements a cost-based optimizer that determines the most efficient execution plan using table statistics.
- Real-time Data Synchronization - Synchronizes datasets in real-time using primary key upserts and deletes to keep analytics current.
- Vectorized Execution Engines - Utilizes a vectorized execution engine with SIMD instructions to process data in batches for high analytical throughput.
- Lakehouse Querying - Runs high-performance SQL queries directly on open table formats in a data lake without requiring file imports.
- Shared-Nothing Processing Engines - Employs a shared-nothing distributed processing model where each node manages its own local storage and memory.
- Business Intelligence Connectors - Bridges the high-speed engine with business intelligence platforms using standard MySQL protocols and ANSI SQL.
- Materialized Views - Provides automated materialized views that pre-calculate result sets to accelerate query response times.
- Materialized View Selectors - Implements a cost-based optimizer to automatically route queries to the most efficient pre-calculated materialized views.
- Multi-Tenant Resource Isolation - Prevents query interference by allocating specific CPU and memory quotas to individual users or workloads within the cluster.
- MySQL Compatibility - Uses the MySQL protocol to ensure compatibility with standard SQL clients and BI tools.
- Scalable Database Clusters - Provides a scalable database cluster architecture that automatically balances resources during node scaling.
- SQL Database Connectivity - Provides connectivity and compatibility with existing business intelligence tools and database clients via standard MySQL protocols.
- Workload Isolation - Implements multi-tenant resource isolation to manage CPU and memory quotas across concurrent workloads.
- Cluster Scaling Orchestrators - Automatically balances resources and recovers data replicas when adding or removing nodes from the cluster.
