OpenLake:What is OpenLake

Last Updated:Jan 28, 2026

Overview

Alibaba Cloud OpenLake is a next-generation open lakehouse platform for big data, search, and artificial intelligence (AI) integration scenarios. The platform builds a unified metadata catalog on Data Lake Formation (DLF). It combines structured, semi-structured, unstructured, and vector data. This creates an Agentic Data architecture that uses a single copy of data with multiple engines, global search, and end-to-end governance.

OpenLake supports popular open table formats such as Paimon, Iceberg, and Lance. It provides a complete workflow from data ingestion, feature engineering, and vectorization to retrieval-augmented generation, model training, and inference. OpenLake offers enterprises a high-performance, low-cost, high-availability (HA), and easy-to-manage infrastructure for multimodal data.

The platform is suitable for enterprises in industries such as the Internet, finance, retail, manufacturing, education, and autonomous driving. These enterprises need to process multimodal data and build AI-native applications.

Benefits

Open standards to break down data silos

  • It is fully compatible with open source table formats such as Paimon, Iceberg, and Lance. It also supports open file standards such as Parquet, ORC, Avro, and CSV.

  • It seamlessly integrates with popular compute engines such as Spark, Flink, Trino, StarRocks, Hologres, and MaxCompute. This avoids the costs of data migration and format conversion.

  • It uses the DLF Omni Catalog to create a unified catalog for five data types: structured, semi-structured, unstructured, vector, and streaming. This lets you ingest data once and use it anywhere.

High-performance engine collaboration for efficient computing

  • Multiple engines, such as Spark, Flink, StarRocks, Hologres, and MaxCompute, can access the same lake data without redundant copies.

  • The unified DLF metadata service ensures consistent permissions, schema synchronization, and transaction isolation across engines.

  • Batch processing, stream computing, interactive queries, and AI training share the same storage. This significantly improves resource utilization and end-to-end efficiency.

  • It supports high-concurrency, low-latency mixed workloads. This meets the needs of scenarios that require both T+1 batch processing and real-time analytics with latency at the second level.

Unified development and governance to reduce complexity

  • OpenLake Studio, integrated with DataWorks, provides a unified development experience with a Notebook, a SQL IDE, and visual scheduling.

  • Centralized management of metadata, data permissions, data lineage, task orchestration, and quality monitoring enables governance from the start of development.

  • It supports large-scale, high-concurrency task scheduling to ensure enterprise-grade Service-Level Agreements (SLAs) and stability.

  • The entire data pipeline is traceable, auditable, and supports rollbacks to meet compliance requirements.

Data, Search, and AI integration to unlock data value

  • It combines structured tables, unstructured files (such as images, audio, video, and documents), and vector data to build a unified, multimodal lakehouse.

  • It natively supports SQL queries, full-text search (OpenSearch or Elasticsearch), and vector similarity search (Milvus or PgVector).

  • It provides a high-quality, searchable, and governable data pipeline for Large Language Model (LLM) retrieval-augmented generation (RAG) and intelligent agents.

  • It streamlines the entire workflow from data ingestion, feature engineering, and vectorization to retrieval augmentation and model inference. This accelerates the implementation of AI applications.
