- def flowTry[T](parallelism: Int, toStatement: (T) => DBIO[Int])(implicit session: SlickSession): Flow[T, Try[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.

It return Success[Int] or Failure[Throwable] if there was an exception during the execution.
- 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 flowTry[T](toStatement: (T) => DBIO[Int])(implicit session: SlickSession): Flow[T, Try[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 try executing those statements against the specified Slick database.
