What are some lightweight options for persistence in Groovy? I've considered serialization and XML so far but I want something a bit more robust than those, at least so I don't have to rewrite the entire file every time. Ideally, it would:

  • Require no JARs in classpath, using Grapes instead
  • Require no external processes, administration, or authentication (so all embedded)
  • Support locking

I plan on using it to cache some information between runs of a standalone Groovy script. I imagine responses will focus around SQL and NoSQL databases. Links to pages demonstrating this usage would be appreciated. Thanks!
