Epic

EPIC-05 Database Optimization

Description

Query timeouts not set in code; connect options minimal.

Current Behavior

Driver defaults only.

Expected Behavior

Documented serverSelectionTimeoutMS / socketTimeoutMS (or equivalent) appropriate to serverless.

Why This Matters

Fail fast under DB distress instead of hanging workers.

Affected Files

• exsolvia-frontend/lib/mongodb.ts

Affected Functions / APIs

• All DB-backed routes

Evidence From Audit

Audit Database Security — Query timeouts Not set.

Risk / Impact

Hung requests exhausting concurrency.

Recommended Direction

Set conservative timeouts; verify in staging.

Acceptance Criteria

• Timeouts configured in connect options
• Values documented
• App still connects successfully under normal latency

Testing Requirements

• Integration test

Dependencies

• None

• Related to: ISSUE-EXS-041

Estimated Complexity

Small

Priority Reason

Resource exhaustion resilience.

Notes

None.
