What is AWS Lambda SnapStart priming with Aurora DSQL?

It's pre-loading DB connections and classes before snapshotting the Lambda environment, using CRaC hooks—so cold starts mimic warm ones.

How do you implement DSQL request priming in Java Lambda?

Add org-crac dep, implement Resource in handler, call dao.method() in beforeCheckpoint. Register in constructor.

Does Lambda SnapStart priming work with Java 25 and Hibernate?

Yes—benchmarks show massive cold start cuts, even with ORM bloat. But leaner alternatives shine brighter.
