How to automatically send flat file with latest SpringBoot 3 + Batch + Integration to sftp server

Nice tutorial. I am building something quiet similar but my problem is that the file can be huge. How do we modify this so that we don't get a out of heap memory error. May be use streams in some way and append the file on the remote server?

Hi, thank you very much for the tutorial. I have error Violation d'index unique ou clé primaire: "PUBLIC.JOB_INST_UN_INDEX_3 ON PUBLIC.BATCH_JOB_INSTANCE(JOB_NAME NULLS FIRST, JOB_KEY NULLS FIRST) VALUES .
And it persists even if I generate all tables.
Thank you
