Cold Start Elimination in Serverless Kotlin
📰 Dev.to · SoftwareDevs mvpfactory.io
Eliminate cold starts in serverless Kotlin functions using AWS SnapStart, CRaC, or GraalVM native image, and learn how to overcome Kotlin-specific challenges
Action Steps
- Compare AWS SnapStart's firecracker snapshot approach with CRaC and GraalVM native image for cold start elimination
- Configure AppCDS archive generation pipeline to reduce class loading overhead
- Apply coroutine dispatcher pool resurrection after checkpoint to avoid stale state
- Test and benchmark the memory and latency performance of each approach
- Optimize lazy delegates to restore fresh state instead of stale state
