Configuration (optional)

Metatron Discovery loads its configuration from the files under “/conf” directory by default. We already wrote some frequent configurations in the template files. For your own configuration of Metatron Discovery application, you should create a new configuration file with reference to the pre-distributed template file as belows. In the generated setting file, refer to the configuration guide and specify detailed setting information.

$ cp ./conf/application-config.templete.yaml ./conf/application-config.yaml

To configure the environment in which the server is running, you need to configure server memory or classpath settings by editing the “metatron-env.sh” file.

$ cp ./conf/metatron-env.sh.templete ./conf/metatron-env.sh

For example, if you want to use MySQL and increase the memory, you should set it as below. See the comments in the file “metatron-env.sh.templete” for more information.

export METATRON_JAVA_OPTS=-Xms4g -Xmx4g
export METATRON_DB_TYPE=mysql
