Are you saying that Filebeat is resending the whole file rather than just the newly added log lines?

If so, that would mean that Filebeat is not "remembering" that it's reading from the same file. So either it's not the same file (the whole file is being re-written each time it's updated and the file has a new inode) OR Filebeat is cleaning its persisted state for the inode at some point.

How is the CSV file being updated? Filebeat expects log files to be appended to.
