    Construct a Transactor that wraps an existing Connection.

    Construct a Transactor that wraps an existing Connection. Closing the connection is the responsibility of the caller.

  14. def fromDataSource[M[_]]: FromDataSourceUnapplied[M]

    Construct a constructor of Transactor[M, D] for some D <: DataSource When calling this constructor you should explicitly supply the effect type M e.g.

    Construct a constructor of Transactor[M, D] for some D <: DataSource When calling this constructor you should explicitly supply the effect type M e.g. Transactor.fromDataSource[IO](myDataSource, connectEC)

  15. def fromDriverManager[M[_]]: FromDriverManagerUnapplied[M]

    Module of constructors for Transactor that use the JDBC DriverManager to allocate connections.

    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 by default, 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.
