MariaDB 11.8 LTS Option on Frappe Cloud (Vector Search Support)

Frappe Cloud

Hi everyone,

Following up on the earlier discussion about MariaDB 11.7 with Vector Search, I’d like to formally request MariaDB 11.8 LTS as an option on Frappe Cloud.

Why?

MariaDB 11.8 is now the current LTS (GA since June 2025, now on 11.8.6). Its headline feature is native vector search — VECTOR data type, cosine/euclidean similarity functions, and HNSW indexing. This is critical for developers building AI-powered Frappe apps (RAG, semantic search, similarity matching).

Right now, Frappe Cloud runs MariaDB 10.6. Developers who want vector search in their Frappe apps are forced to either:

  1. Use an external vector database (adds sync complexity, external service dependency, and makes apps hard to distribute)
  2. Self-host outside Frappe Cloud (defeats the purpose of the managed platform)

What’s been validated

@tukutela confirmed that ERPNext v15 runs fine on MariaDB 11.8.3 with the only change being innodb_snapshot_isolation = OFF. Amazon RDS has also added 11.8 support.

The ask

Could the Frappe Cloud team consider:

  1. Adding MariaDB 11.8 as a selectable database version for new benches
  2. Providing an upgrade path for existing benches (10.6 → 11.8)
  3. Eventually supporting the VECTOR field type in the framework itself

This would make Frappe Cloud the natural home for AI-powered Frappe apps, rather than pushing those developers to self-host.

I’ve also filed related issues on:

Would love to hear from the team and other developers interested in this. Anyone else building AI features on Frappe?
