AST Query Compiler

Param Bound ($1)

// Directus JSON Filter Payload:

GET /items/ref_indonesia_banks?filter={"category":{"_eq":"Himbara"}}

// Compiled Go AST SQL (Zero SQLi Injection Risk):

SELECT "id", "name", "code", "category" FROM "ref_indonesia_banks" WHERE ("category" = $1) LIMIT 10

In-App PBAC Evaluation

Row-Level Security injected into query AST in 1.76 µs. Zero allocations, zero goroutine leaks.

Engine Architecture

Designed for Multi-Instance, Run as One

Eliminating enterprise runtime bloat without sacrificing Directus 11 API specifications, relational integrity, or developer velocity.

Directus 11 Dynamic REST & QUERY

Full specification compliance for Directus operators: _eq, _in, _contains, deep relational lookups, pagination, and multi-field sorting.

Transactional DDL Compiler (UC-01)

Dynamic schema generation with atomic transaction rollback guards. Guarantees zero dirty or half-migrated states via PostgreSQL savepoints on failure.

AST SQL Injection Proofing (UC-02)

Doug Martin goqu/v9 abstract syntax tree compiler. Enforces parameterized query binding ($1, $2) across all arbitrary filter inputs.

In-App PBAC & RLS Masking

Evaluates Policy-Based Access Control in <2 µs with zero heap allocations. Automated dynamic tenant isolation and field-level masking for non-admin roles.

Relational Delta Sync (UC-03)

Offline-first delta synchronization engine with Last-Write-Wins (LWW) conflict resolution and immutable conflict audit logging in nts_sync_conflicts.

Native Model Context Protocol (MCP)

Built-in AI Agent protocol endpoint (/mcp). Enables Claude, Cursor, and autonomous agent loops to inspect schemas and execute governed database actions safely.

FinOps Sovereignty

98% Less Memory. Zero Cold Starts.

Compare runtime memory consumption and container overhead against traditional Node.js/Java headless platforms.

Platform Engine	Runtime Stack	Idle Memory (RAM)	Under 10k Concurrency	Container Footprint	Cold Start
NusaTech StudioOur Engine	Go 1.26 + Chainguard Static	< 3.2 MB	18.5 MB (< 20MB limit)	11.8 MB (Wolfi rootless)	< 8 ms
Directus (Legacy)	Node.js 20 + Vue 3	180 – 250 MB	420 – 650 MB	~ 280 MB	1,800 – 3,500 ms
Strapi CMS	Node.js 20 + React	240 – 380 MB	550 – 850 MB	~ 350 MB	2,500 – 4,800 ms
