For the database layer, I am currently weighing up ODB, Oat++, SOCI, cppdb, and sqlpp11 [if sqlpp adds support for CREATE TABLE]. You here at drogon seem to have your own [ORM](https://en.wikipedia.

I have a small piece of zlayer code. The layers are defined as vals, like so:

  private final val kafkaLayer: Layer[Error, Kafka]                                      = Config.live >>> Kafka.live
  private final val transactorLayer: Layer[Error, DbTransactor]                          = (Blocking.live ++ ConfigDb.live) >>> db.hikariLayer
  private final val queryConfigLayer: Layer[

It would be really useful if we had a simple Dockerfile containing the build instructions for the library. Then, we could create an image which would be easy to distribute and run for the volunteer participants without setting up the environment themselves.
