Features

• Distributed SQL Databases - Functions as a relational database engine designed to scale horizontally while maintaining transactional consistency.
• Hybrid Transactional Analytical Processing Systems - Functions as a hybrid transactional and analytical processing engine, allowing real-time analytics and transactions on a single data copy.
• Hybrid Storage Formats - Optimizes for both transactions and analytics by storing data in both row and column formats within the same system.
• Cross-Zone Data Distribution - Replicates data across multiple logical zones using a consensus protocol to ensure high availability.
• Database Compatibility Layers - Provides native compatibility layers for MySQL and Oracle to migrate legacy workloads without rewriting SQL code.
• Strongly Consistent Data Stores - Maintains strong consistency across distributed replicas using a Paxos-based leader-follower replication model.
• Disaster Recovery Solutions - Ensures business continuity via synchronous replication and automated failover across geographically distributed infrastructure.
• Distributed Consensus Protocols - Uses the Paxos consensus protocol to maintain strong data consistency across distributed replicas.
• Distributed Consensus Stores - Uses a Paxos-based distributed store for synchronous replication and high availability across data zones.
• Distributed Transaction Processing - Maintains ACID consistency across a distributed SQL environment to ensure data integrity for critical workloads.
• Horizontal Database Scaling - Expands a single cluster across thousands of nodes to manage petabytes of data and trillions of records.
• Horizontal Scaling - Increases read and write capacity by automatically balancing and routing data across new nodes.
• HTAP Databases - A hybrid system that executes real-time analytics and transactions on a single data copy.
• Multi-Tenant Data Management - Provides administrative interfaces for creating tenants, managing resource units and isolating data.
• Multi-Tenant Resource Isolation - Implements a multi-tenant architecture that isolates CPU, memory, and I/O resources for different tenants within a single cluster.
• MySQL Compatibility - Supports MySQL compatibility layers to migrate legacy workloads without extensive code rewrites.
• Real-Time Analytics - Executes complex reporting and live dashboards directly on transactional data with low latency.
• Vector Databases - Provides a storage engine capable of indexing and querying high-dimensional vector embeddings for semantic search.
• Vector Search - Indexes and queries high-dimensional vector data to enable semantic search and recommendation systems.
• Multi-Region Replication - Replicates data across different physical zones in real-time to ensure zero data loss during regional failures.
• High Availability Services - Maintains continuous service uptime using automated failover and zero data loss across racks and regions.
• Multi-Tenant Isolation - Separates CPU, memory, and I/O resources for each tenant using a native multitenancy architecture.
• Compatibility Layers - Provides compatibility layers for Oracle and MySQL dialects to allow legacy applications to run without SQL rewrites.
• Kubernetes Operators - Provides a dedicated Kubernetes operator to automate the provisioning and management of database clusters.
• Standby Management - Supports creating standby tenants, restoring standbys from backups, and executing primary-standby switchovers.
• Columnar Storage Engines - Lowers costs and resource usage through a hybrid row-columnar storage engine.
• Cluster Request Routing - Implements mechanisms for directing SQL requests to specific nodes based on data distribution across the cluster.
• Data Compression Algorithms - Reduces storage footprint and accelerates queries using dictionary, run-length, and differential compression.
• Replica Recovery - Performs single-node or cluster-wide recovery and automated re-synchronization of data to replacement nodes.
• Query Routing - Automatically resolves data distribution and shard locations to route queries to the appropriate server.
• Traffic Scaling Strategies - Implements distributed architecture to maintain predictable performance and data consistency during traffic surges.
• Hybrid Search - Combines vector similarity with structured metadata and full-text lookups in a single request.
• Hybrid Vector-Keyword Indexing - Combines structured data with vector embeddings in a single storage engine to enable semantic search.
• Log-Stream Balancing - Scales capacity and redistributes load by splitting and migrating data log streams between cluster nodes.
• Table-Level Storage Formats - Allows defining row, column, or hybrid storage formats at the table level to apply schema changes without downtime.
• Multi-Cloud Deployments - Distributes data across different regions and cloud providers to minimize latency and maintain data sovereignty.
• Database Cluster Orchestration - Enables bootstrapping clusters, adjusting topology, scaling nodes, and modifying system parameters to maintain cluster health.
• High Availability Systems - Implements architectural patterns to ensure continuous service availability and fault tolerance across distributed nodes.
• Data - Automatically rebalances data and service loads by splitting, merging, and migrating log streams during scaling.
• Database Access Controls - Provides end-to-end encryption and granular access controls to protect database assets and meet regulatory requirements.
• Database Dialect Migration - Provides compatibility layers for Oracle and MySQL to transition existing database applications without extensive code rewrites.
• Database Management Systems - Distributed relational database built on the Paxos protocol.
• Database Systems - Distributed database designed for high-scale banking applications.
