Technical debt will increase. + +### Q: Can we use Play Framework later? +**A**: Yes, but consider using Play 3.0+ which already uses Pekko instead of Akka. + +### Q: What about performance impact? +**A**: Pekko is based on Akka 2.6, so performance should be similar. Benchmarking is required to confirm. + +### Q: What about other Sunbird projects? +**A**: They'll need separate analysis if they use Akka.

Play Framework Analysis - -### 11.1 Finding: Play Framework Not Used - -**Conclusion:** This repository does **NOT** use Play Framework. - -**Evidence:** -- No SBT build files (build.sbt, plugins.sbt) -- No Play dependencies in Maven POMs -- Maven is the only build tool -- No Play-specific code structures - -### 11.2 Play Framework Context - -Play Framework is typically used in SBT-based Scala/Java web applications. This repository is: -- A utility library (not a web app) -- Maven-based (not SBT) -- Provides common utilities for Sunbird platform - -### 11.3 If Play Framework Were Added - -**Hypothetical Scenario:** If Play Framework were to be added in the future: - -**Play 2.8.x with Akka:** -- Last Play version with Apache 2.0 Akka -- Would require Akka 2.6.x -- SBT or Maven can be used - -**Play 3.0.x with Pekko:** -- Uses Pekko instead of Akka -- Requires migration to SBT or using Maven with Pekko -- Not yet stable (as of 2024) - -**Recommendation:** Since Play is not used, focus solely on the Akka → Pekko migration. - ---- - -## 12. Conclusion - -### 12.1 Summary - -| Aspect | Finding | -|--------|---------| -| **Akka Usage** | Yes - Akka 2.5.19 with Scala 2.11 | -| **Play Framework** | No - Not used in this repository | -| **Build System** | Maven (not SBT) | -| **Migration Feasibility** | Feasible with phased approach | -| **Estimated Effort** | 14-20 weeks | -| **Recommendation** | Proceed with migration | - -### 12.2 Final Recommendations - -1. **DO NOT use Play Framework/SBT** - This requirement is not applicable to this repository. - -2. **DO Migrate from Akka to Pekko** following this path: - - Phase 1: Upgrade Scala 2.11 → 2.13 - - Phase 2: Upgrade Akka 2.5.19 → 2.6.21 - - Phase 3: Migrate Akka 2.6.21 → Pekko 1.x - -3. **DO Create comprehensive tests** before starting migration. - -4. **DO Use phased approach** rather than big-bang migration. - -5. **DO Allocate adequate time** (14-20 weeks with proper testing). - -### 12.3 Next Steps - -1. **Immediate**: Share this report with stakeholders for approval -2. **Short-term**: Set up migration environment and create test suite -3. **Medium-term**: Execute Phase 1 (Scala & Akka 2.6 upgrade) -4. **Long-term**: Complete migration to Pekko and deploy to production - -### 12.4 Success Criteria - -- [ ] All tests pass after migration -- [ ] Performance metrics meet or exceed baseline -- [ ] No regression in functionality -- [ ] Clean build with no warnings -- [ ] Documentation updated -- [ ] Team trained on new stack - ---- - -## 13.

Direct migration from 2.5 to Pekko will fail due to breaking changes. - -### Q: What if we do nothing? -**A**: You'll remain on an outdated, unsupported version with no security updates. Technical debt will increase. - -### Q: Can we use Play Framework later? -**A**: Yes, but consider using Play 3.0+ which already uses Pekko instead of Akka. - -### Q: What about performance impact? -**A**: Pekko is based on Akka 2.6, so performance should be similar. Benchmarking is required to confirm. - -### Q: What about other Sunbird projects? -**A**: They'll need separate analysis if they use Akka.
