Enables transaction mode for a channel.
async amqpclassic.enableTransactionMode(channelName : string): Promise<void>
This method enables transaction mode for the channel with the given ChannelName.
While a channel is in transaction mode, all messages published and acknowledgements sent over it will be part of a transaction, and the server will wait to process them until the transaction is either committed or rolled back.
Keep in mind that, according to the AMQP 0.9.1 specification:
- A new transaction is always started immediately after committing or rolling back the current one, which means that...
- ...a channel will stay in transaction mode, once enabled, until it is deleted.
- Transactions are only guaranteed to be atomic if all messages published and acknowledgements sent affect a single queue.
- Any messages published on a channel in transaction mode that have the Mandatory or Immediate flags set are not guaranteed to be included in the transaction.
An exception is thrown if no channel with the given ChannelName exists, or if EnablePublishConfirms has been called for the specified channel previously.
