- def flow[T](parallelism: Int, toStatement: (T) => DBIO[Int])(implicit session: SlickSession): Flow[T, Int, NotUsed]
Scala API: creates a Flow that takes a stream of elements of type T, transforms each element to a SQL statement using the specified function, and then executes those statements against the specified Slick database.

- parallelism
How many parallel asynchronous streams should be used to send statements to the database. Use a value of 1 for sequential execution.
- toStatement
A function to produce the SQL statement to execute based on the current element.
- session
The database session to use.

- def source[T](streamingQuery: StreamingDBIO[Seq[T], T])(implicit session: SlickSession): Source[T, NotUsed]
Scala API: creates a Source[T, NotUsed] that performs the specified query against the (implicitly) specified Slick database and streams the results.
Scala API: creates a Source[T, NotUsed] that performs the specified query against the (implicitly) specified Slick database and streams the results. This works for both "typed" Slick queries and "plain SQL" queries.
- streamingQuery
The Slick query to execute, which can be either a "typed" query or a "plain SQL" query produced by one of the Slick "sql..." String interpolators
- session
The database session to use.
