Core concepts

There are a couple of core concepts that the API is built upon:

• Asynchronous processing

  Every operation that involves I/O with the database is asynchronous. Methods return Future or Reactive Stream's Publisher instances.

• Thread safety

  rdbc API requires that its implementations must be thread-safe. You are free to share class instances among threads, even those that are mutable.

• Null safety

  SQL NULL values are represented as Option instances. Scala null doesn't have to be used when working with the API.
