There are databases that use the standard kernel Virtual FileSystem (VFS) and storage interfaces instead of managing IO scheduling within the application itself. Significant effort has been expended on ensuring that they are well-behaving applications but there are known problems
and limitations.

The objective of the session is for kernel and database developers to discuss these interfaces, the limitations and potential features that could be implemented to address the problems.  Potential topics will cover the file synchronisation interfaces, problems with IO stalls, IO patterns generated by the workload, page cache interfaces, bug report handling by the kernel community and reproducible test cases. The audience is expected to consist of developers from the PostgreSQL, MySQL, MariaDB and kernel communities but is open to all interested parties.
