Transaction Support

We don't have a way to export this macro.

Pipes utilizes XA transactions for participating in global transactions and for demarcating its local and command-scoped transactions. Pipes uses JBoss Transactions as a transaction manager.

Here are the Pipes transaction scopes:

Scope	Description
`Command`	Treats the user command as if all source commands are executed within the scope of the same transaction. The `AutoCommitTxn` execution property controls the behaviour of command level transactions
`Local`	The transaction boundary is locally defined by a single client session
`Global`	Pipes participates in a global transaction as an XA Resource.

The default transaction isolation level for Pipes is READ_COMMITTED.
