JDBC MySQL connection using Unix Socket

Question

I am using MySQL using the --skip-networking option on Linux.

Trying to connect my J2EE based application (using servlets) to the MySQL database using JDBC.

Answer 1

The JDBC Driver from the MariaDB project supports Unix domain sockets while remaining compatible with the MySQL Connector/J JDBC driver. Example jdbc url for the MariaDB driver is: jdbc:mariadb://localhost:3306/revmgt?localSocket=/var/run/mysqld/mysqld.sock

Worth noting that this requires including the JNA library as the MariaDB driver uses domain sockets via JNA internally. I saw speed improvements for CPU bound java processes when using the unix domain sockets. I believe this was largely from the offload of work from the java process to native code freeing up CPU cycles for the already CPU bottle necked java process.
