object fromDriverManager

Module of constructors for Transactor that use the JDBC DriverManager to allocate connections. Note that DriverManager is unbounded and will happily allocate new connections until server resources are exhausted. It is usually preferable to use DataSourceTransactor with an underlying bounded connection pool (as with H2Transactor and HikariTransactor for instance). Blocking operations on DriverManagerTransactor are executed on an unbounded cached daemon thread pool, so you are also at risk of exhausting system threads. TL;DR this is fine for console apps but don't use it for a web application.
