1.  abstract class JdbcHandler[Envelope, S <: JdbcSession] extends JdbcHandlerLifecycle

   Implement this interface for the Envelope handler for Jdbc Projections.

   Implement this interface for the Envelope handler for Jdbc Projections.

   It can be stateful, with variables and mutable data structures. It is invoked by the Projection machinery one envelope at a time and visibility guarantees between the invocations are handled automatically, i.e. no volatile or other concurrency primitives are needed for managing the state.

   Supported error handling strategies for when processing an Envelope fails can be defined in configuration or using the withRecoveryStrategy method of a Projection implementation.
