I am transferring files at regular intervals to remote system via FTP using a Java client. The files are huge in size(>10MB). A third-party application processes these files in remote path. Now the problem is that file is being created at remote path and while the transfer is still in progress the third-party application starts processing it. I need to avoid this.
Solution suggested by third-party side was to have another file transferred containing size in bytes. Suppose file being transferred is Transaction_20160513_1130.csv then after completion transfer another file Transaction_20160513_1130.size which will be a plain text containing size in bytes of Transaction_20160513_1130.csv
Is there a better solution than the above? This might be a common issue. Hope there is a common solution as well.
