April 2026 brought a strong wave of AI-native capabilities and performance-focused enhancements across Alibaba Cloud's database portfolio. From in-database AI inference to intelligent distributed database management, this month's releases reflect a clear trend: making databases not just smarter, but fundamentally easier to operate at scale.
Here's a quick overview of all releases this month, followed by a deep dive into the three most significant updates.
| Product | Feature | Type |
|---|---|---|
| ApsaraDB RDS for MySQL | Instant Upgrade | New Feature |
| PolarDB-X | AI Assistant for Intelligent O&M | New Feature |
| Lindorm | AI Engine Released | New Feature |
| ApsaraDB for SelectDB | AI Observability (Langfuse-Compatible) | New Feature |
| DTS | Support for MongoDB 8.0 & PostgreSQL 18 | Optimization |
| DMS | Agent Call Package Service | New Feature |
What it is:
Lindorm AI Engine delivers a unified platform for data storage, computation, and model inference — all within a single database service. It supports semantic search, multimodal retrieval, and knowledge-based Q&A natively, without requiring data to leave the database.
Description:
Traditionally, building AI-powered applications means exporting data from your database, loading it into a separate AI platform, running inference, and syncing results back. This creates latency, stale data issues, and security concerns. Lindorm AI Engine eliminates this friction entirely.
With Lindorm AI Engine, you can execute inference tasks — such as RAG-based Q&A, image-text cross-modal retrieval, and embedding-powered semantic search — directly where your data lives. The engine ensures that every query is always grounded in the freshest corpus, while maintaining strict data isolation and compliance.
Why developers and enterprises should pay attention:
What it is:
PolarDB-X AI Assistant is a purpose-built intelligent operations tool that lets DBAs interact with their distributed database clusters using natural language. It provides intelligent Q&A, automated root cause diagnosis, and proactive inspection capabilities.
Description:
Managing a distributed database at scale — with multiple shards, complex SQL routing, and elastic scaling decisions — traditionally demands deep expertise and significant manual effort. PolarDB-X AI Assistant changes this equation.
The assistant can analyze multi-node performance data, identify root causes of degradation, recommend shard rebalancing strategies, and provide SQL routing optimization suggestions — all through a conversational interface. It understands PolarDB-X internals and can generate actionable recommendations that previously required senior DBA intervention.
Why developers and enterprises should pay attention:
What it is:
ApsaraDB RDS for MySQL now supports Instance Upgrade — a capability that allows you to scale up instance specifications and expand storage in seconds, with no data migration, no connection blips, and no service interruption.
Description:
Scaling a database instance has historically been one of the most anxiety-inducing operations in production environments. Even "online" scaling often involves brief connection drops, temporary performance degradation during data migration, or maintenance windows that must be carefully scheduled.
Instant Upgrade eliminates these concerns entirely. When the underlying physical resources permit, RDS for MySQL can instantly adjust CPU, memory, and storage allocations without moving any data. The process is completely transparent to applications — no reconnection logic needed, no failover triggered, no queries interrupted.
This feature is available for MySQL 5.7 and later versions running on Premium Local SSDs instances.
Why developers and enterprises should pay attention:
SelectDB now offers built-in AI Observability, fully compatible with the open-source Langfuse platform. If you're building AI Agent applications, you can now leverage SelectDB for application log analysis, Token consumption monitoring, and Prompt lifecycle management — all within a high-performance analytical database.

Data Transmission Service (DTS) now supports synchronization for MongoDB 8.0 and PostgreSQL 18. As organizations adopt the latest open-source database versions, DTS ensures your data pipelines remain uninterrupted and fully supported.
For teams heavily leveraging DMS's Data Agent and Meta Agent capabilities, the new Agent Call Package provides a flexible pay-as-you-go model to cover excess API requests and knowledge retrieval usage beyond your plan quota. Currently available in Hangzhou, Singapore, and Jakarta regions.
April's releases signal Alibaba Cloud's accelerating investment in AI-native database capabilities. From Lindorm's in-database inference engine to PolarDB-X's conversational O&M assistant and SelectDB's Langfuse-compatible observability, the message is clear: the future database is not just a data store — it's an intelligent platform that understands, reasons, and acts.
