[$] Better guidance for database developers
At the inaugural Databases
microconference at the 2019 Linux Plumbers Conference (LPC), two
developers who work on rather different database systems had similar
complaints about developing for Linux. Richard Hipp, creator of the SQLite
database, and Andres Freund from the PostgreSQL project both lamented the
lack of
definitive documentation on how to best use the kernel's I/O interfaces,
especially for corner cases. Both of the sessions, along with others in
the microconference, pointed to a strong need for more interaction between
user-space and kernel developers.
