-------------------------------------------
Summary: Remove `O_SYNC` from StatusUpdateManager logs
Key: MESOS-5944
URL: https://issues.apache.org/jira/browse/MESOS-5944
Project: Mesos
Issue Type: Improvement
Components: slave
Reporter: Joris Van Remoortere
Assignee: Joris Van Remoortere
Fix For: 1.1.0
Currently the {{StatusUpdateManager}} uses {{O_SYNC}} to flush status updates
to disk.
We don't need to use {{O_SYNC}} because we only read this file if the host did
not crash. {{os::write}} success implies the kernel will have flushed our data
to the page cache. This is sufficient for the recovery scenarios we use this
data for.
