Project Title

oceanbase — The Fastest Distributed Database for Transactional, Analytical, and AI Workloads

Overview

OceanBase is a high-performance, distributed relational database developed by Ant Group. It stands out for its ability to handle transactional, analytical, and AI workloads efficiently. OceanBase is built on a common server cluster, providing high availability, linear scalability, and support for vector database functionality, making it suitable for AI applications and large-scale retrieval scenarios.

Key Features

Vector Search: Supports vector indexing and efficient queries for AI applications, recommendation systems, and semantic search.
Transparent Scalability: Capable of managing 1,500 nodes, PB data, and a trillion rows of records in one cluster.
Ultra-fast Performance: Achieved TPC-C 707 million tmpC and TPC-H 15.26 million QphH @30000GB.
Cost Efficiency: Saves 70%–90% of storage costs.
Real-time Analytics: Supports HTAP without additional cost.

Use Cases

Financial Institutions: For managing large transactional data and real-time analytics.
AI and Machine Learning: Efficient vector search capabilities for AI workloads.
Large-Scale Retrieval: Semantic search and recommendation systems requiring high throughput and low-latency.

Advantages

High Availability: Based on the Paxos protocol, ensuring system reliability.
Linear Scalability: Supports expansion without performance degradation.
Cost-Effective: Significantly reduces storage costs.
Versatile: Handles a wide range of workloads from transactions to analytics.

Limitations / Considerations

Hardware Dependency: Not dependent on specific hardware architectures, but performance may vary across different setups.
Complexity: May require expertise to manage and optimize for large-scale deployments.

CockroachDB: A cloud-native SQL database for building global, scalable cloud services, differing in its cloud-native approach.
TiDB: An open-source, distributed HTAP database that handles large data volumes, with a focus on hybrid transactional/analytical processing.
Cassandra: A distributed NoSQL database designed to handle large amounts of data across many commodity servers, known for its high availability.
