Important:  In Remote Transfer mode, the file is deleted from the remote server after it is transferred to the local directory by the FileInput node for processing. The FileInput node creates an mqsitransitin  subdirectory in the input directory. The mqsitransitin subdirectory holds and locks the input files while they are being processed. If an integration server crashes while processing the file, the partially processed file can be recovered from the mqsitransitin  subdirectory of the local input directory and can be submitted for reprocessing. 

In the Kubernetes environment, if the IBM App Connect Integration Server Pod crashes, a new replacement Pod is spawned by Kubernetes from the base Docker image. The data or state is lost when the container/Pod dies because the file system inside the container is temporary. Therefore, you might lose the partially processed file because it is held in the local directory inside the container in the following scenario: 

You are processing a file inside container in Remote Transfer mode, and the container /Pod crashes for some reason. 

Therefore, when you use the Remote Transfer option for processing files, you need to ensure that you have a backup copy of the files on the remote server. That way, the files can be resubmitted for processing in the event of failure due to pod or integration server crash. 

For file-based integration, Remote Transfer option is recommended instead of consuming the files via file system mounts that use persistent volume claim (PVC). 

## 7.8.8 Considerations for integrating IBM App Connect with IBM Event Streams 

IBM Event Streams is a scalable, distributed, high-throughput message bus, which supports a number of client protocols including Kafka. You can use the KafkaProducer and KafkaConsumer nodes in IBM App Connect to receive messages from and send messages to IBM Event Streams. 

The following steps provide detail on how to configure a connection from IBM App Connect to IBM Event Streams that runs within the Cloud Pak for Integration platform. Similar steps can be used for connecting to an external event streams instance.
