## Pre-Read Summary
|
|
|
|
### Background
|
|
|
|
Our MongoDB database is experiencing performance degradation as we scale. Query response times have increased from 50ms to 400ms average over the past 6 months. The schema-less nature that initially provided flexibility is now causing data consistency issues and making application logic more complex.

|
|
|
|
### Current Situation
|
|
|
|
**Performance metrics**:
|
|
- Average query time: 400ms (was 50ms 6 months ago)
|
|
- p95 query time: 1.2s (was 200ms)
|
|
- Database size: 500GB (growing 20GB/month)
|
|
- Connection pool exhaustion during peak traffic
|
|
|
|
**Technical debt**:
|
|
- 15+ application-layer validation rules compensating for lack of schema
|
|
- Complex data migration scripts for schema changes
|
|
- Limited transaction support causing race conditions
|
|
|
|

|
|
|
|
### Historical Context
|
|
|
|
We successfully migrated from Redis to Memcached in 2023, which took 6 weeks. Key learnings:
|
|
- Underestimated application code changes (3 weeks instead of 1 week)
|
|
- Rollback plan was crucial when we discovered compatibility issues
|
|
- Parallel running period (dual writes) was essential for safe migration
|
|
|
|
**Source**: <mention-page url="...">Previous Migration Post-mortem</mention-page>
|
|
|
|
## Decision Required
|
|
|
|
**Question**: Which database migration strategy should we adopt?
|
|
|
|
**Timeline**: Need decision by end of week to include in Q4 planning
|
|
|
|
**Impact**:
|
|
- Engineering team (4-8 weeks of work)
|
|
- Application architecture
|
|
- Operations & monitoring
|
|
- Future feature development velocity
|
|
|
|
## Options Analysis
|
|
|
|
### Option A: Stay on MongoDB with Optimizations
|
|
|
|
**Description**: Invest in MongoDB performance tuning, add indexes, upgrade to latest version, implement better query patterns.
|
|
|
|
**Pros**:
|
|
- ✅ No migration complexity
|
|
- ✅ Team familiar with MongoDB
|
|
- ✅ Can implement immediately
|
|
- ✅ Lower risk
|
|
- ✅ Estimated 2 weeks effort
|
|
|
|
**Cons**:
|
|
- ❌ Doesn't solve fundamental schema flexibility issues
|
|
- ❌ Still limited transaction support
|
|
- ❌ Performance improvements may be temporary
|
|
- ❌ Continues technical debt accumulation
|
|
|
|
**Cost/Effort**: 2 weeks engineering + $5K/year additional MongoDB infrastructure
|
|
|
|
**Risk**: Medium - Improvements may not be sufficient
|
|
|
|
**Source**: <mention-page url="...">Migration Options Analysis</mention-page>
|
|
|
|
### Option B: Migrate to PostgreSQL
|
|
|
|
**Description**: Full migration from MongoDB to PostgreSQL. Redesign schema with proper constraints, implement dual-write period, then cut over.
|
|
|
|
**Pros**:
|
|
- ✅ Solves schema consistency issues
|
|
- ✅ Full ACID transactions
|
|
- ✅ Better performance for relational queries
|
|
- ✅ Lower long-term complexity
|
|
- ✅ Industry standard, easier hiring
|
|
|
|
**Cons**:
|
|
- ❌ High migration effort (6-8 weeks)
|
|
- ❌ Requires schema redesign
|
|
- ❌ Application code changes extensive
|
|
- ❌ Risk of data loss during migration
|
|
- ❌ Downtime required (4-6 hours estimated)
|
|
|
|
**Cost/Effort**: 8 weeks engineering + $8K migration costs - $15K/year MongoDB savings = net $7K/year savings
|
|
|
|
**Risk**: High - Complex migration, application changes required
|
|
|
|
**Recommendation**: ✅ **Favored by engineering team**
|
|
|
|
**Source**: <mention-page url="...">Database Migration Proposal</mention-page>
|
|
|
|
### Option C: Hybrid Approach
|
|
|
|
**Description**: Keep MongoDB for document-heavy data (logs, analytics), migrate transactional data to PostgreSQL. Run both databases.
|
|
|
|
**Pros**:
|
|
- ✅ Phased migration (lower risk)
|
|
- ✅ Use best tool for each data type
|
|
- ✅ Can migrate incrementally
|
|
- ✅ Smaller initial scope (4 weeks)
|
|
|
|
**Cons**:
|
|
- ❌ Increased operational complexity
|
|
- ❌ Two databases to maintain
|
|
- ❌ Data consistency between databases challenging
|
|
- ❌ Higher infrastructure costs
|
|
- ❌ Complex application logic
|
|
|
|
**Cost/Effort**: 4 weeks initial + ongoing complexity + $10K/year additional infrastructure
|
|
|
|
**Risk**: Medium - Operational complexity increases
|
|
|
|
**Source**: <mention-page url="...">Migration Options Analysis</mention-page>
|
|
|
|
### Option D: Do Nothing
|
|
|
|
**Description**: Accept current performance and continue with MongoDB as-is.
|
|
|
|
**Implications**:
|
|
- Performance continues to degrade
|
|
- Technical debt increases
|
|
- Feature development slows
|
|
- Customer experience suffers
|
|
- Eventually forced into emergency migration
|
|
|
|
**Not recommended**
|
|
|
|
