ccding opened a new pull request #10405:
URL: https://github.com/apache/kafka/pull/10405
Kafka does not call fsync() on the directory when a new log segment is
created and flushed to disk.
The problem is that following sequence of calls doesn't guarantee file
durability:
fd = open("log", O_RDWR | O_CREATE); // suppose open creates "log"
write(fd);
fsync(fd);
If the system crashes after fsync() but before the parent directory has been
flushed to disk, the log file can disappear.
This PR is to flush the directory when flush() is called for the first time.
