How does newTempHashMap work in mapdb? Is it just a file-backed hash map or is there an in-memory caching layer?

It creates file in temporary folder. File gets deleted when JVM exits.

  • Thanks! Is there a limitation on the number of temp hash maps that should be used in a single app? Is it ok to use about 100 maps? – Pinch May 20 '15 at 20:36
