100 MONGODB CLUSTER REORGANIZATION

Documentation for Sessions

Session 100: MongoDB Cluster Reorganization

Date: February 8, 2026 Status: Complete (gspace1), Pending Decision (gmodules1) Branch: session-100

Summary

Reorganized MongoDB Atlas infrastructure to properly name clusters by purpose, migrated documentation data, and provisioned production-ready Atlas cluster for Vitto backend.

Changes Made

1. Data Migration: test-modules -> GoGrab-Docs

Source: test-modules.7hkxufn.mongodb.net / docs-database
Target: gograb-docs.z422vsq.mongodb.net / docs-database
Method: mongodump + mongorestore
Result: 585 documents + 5 collections + all indexes migrated with 0 failures
Collections: doc-files (585 docs), doc-projects, search-events, doc-settings, page-views

2. Environment Variable Rename

Old Name	New Name	Rationale
`MONGODB_CONNECTION_STRING_TEST_MODULES`	`MONGODB_CONNECTION_STRING_DOCS`	Reflects actual purpose (docs, not test modules)
`VITTO_MONGODB_URI` (localhost)	`VITTO_MONGODB_URI` (Atlas SRV)	Production-ready Atlas cluster

3. New Vitto Atlas Cluster

Cluster: Vitto (vitto.urgh5aw.mongodb.net)
Tier: Flex (pay-as-you-go, max $30/month)
Database: vitto-mind
Collections (6): execution-traces, strategy-memories, agent-performance, user-patterns, autonomy-config, autonomy-checkpoints

4. Source Code Changes (gspace1)

File	Change
`.env.local`	Renamed var + new connection strings
`apis/backend-docs-api/src/app/app.module.ts`	`connectionStringKey: 'MONGODB_CONNECTION_STRING_DOCS'`
`apis/backend-docs-api/src/app/constants.ts`	Updated comment
`apis/backend-docs-api/src/main.ts`	Updated comments + log message
`apis/backend-ai-api/src/app/infrastructure/services/session-docs.service.ts`	Updated comment
`tools/scripts/database/env-loader.js`	New `getMongoDBDocsConnectionString()`, deprecated old function with backward compat
`tools/scripts/database/sync-session-docs-to-mongodb.js`	Updated comment
`deployment/ENV_LOCAL_TEMPLATE.md`	Updated template var name
`deployment/deploy-docs-api.sh`	Updated Railway instructions

5. Build Verification

backend-docs-api: Compiles successfully
backend-vitto-api: Compiles successfully

Current MongoDB Atlas Architecture (Post-Migration)

Cluster	Host	Tier	Purpose	Databases
GoGrabSpace	`gograbspace.dgajj2t.mongodb.net`	M10	Main platform	`gograb-api`, `ai-context`, `ai-agents`, `ai-memory`, `ai-mcp-dev`, `ai-archive`
GoGrab-Docs	`gograb-docs.z422vsq.mongodb.net`	Flex	Documentation	`docs-database`
Vitto	`vitto.urgh5aw.mongodb.net`	Flex	Vitto Super-Agent	`vitto-mind`
~~test-modules~~	~~`test-modules.7hkxufn.mongodb.net`~~	—	TO BE DELETED	~~`docs-database`~~ (migrated)

Pending: gmodules1 Decision Required

The gmodules1 monorepo actively uses test-modules cluster:

.env.local: MONGODB_CONNECTION_STRING -> test-modules cluster, database sample_supplies
.env: MONGODB_CONNECTION_STRING -> test-modules cluster, database test-modules
storage-system library reads MONGODB_CONNECTION_STRING (defaults to gograbspace in code)
ai-gateway app uses separate MONGODB_URI (localhost, independent)

Options:

Point gmodules1 to gograbspace main cluster (storage-system already defaults to it)
Create a dedicated GoGrab-Modules cluster for module testing
Remove MongoDB config entirely if not actively needed

Recommendation: Option 1 is simplest. The sample_supplies database is likely Atlas sample data, and storage-system defaults to gograbspace anyway. Simply update .env.local and .env to point to gograbspace.

Pending: Railway Deployment Updates

When deploying, update these Railway environment variables:

backend-docs-api: Rename MONGODB_CONNECTION_STRING_TEST_MODULES to MONGODB_CONNECTION_STRING_DOCS with new GoGrab-Docs connection string
backend-vitto-api: Set VITTO_MONGODB_URI to mongodb+srv://paco:[email protected]/vitto-mind

Pending: test-modules Cluster Deletion - ignore this for now

Only delete after:

Verifying backend-docs-api connects to GoGrab-Docs successfully in production
Deciding gmodules1 migration path
Confirming no other projects reference test-modules
