The sticky option is an optional value that can be used to allow the immediate reading of records that have been written to the database during the current request cycle. Use the SELECT statement to query the user information from the pgcatalog. When multiple values exist in the host configuration array, a database host will be randomly chosen for each request. Use du or du PostgreSQL Show Databases command to list all users in the current database server. The database credentials, prefix, character set, and all other options in the main mysql array will be shared across both connections. So, in this case, 192.168.1.1 will be used as the host for the "read" connection, while 192.168.1.3 will be used for the "write" connection. You only need to place items in the read and write arrays if you wish to override the values from the main mysql array. The rest of the database options for the read and write connections will be merged from the main mysql configuration array. The read and write keys have array values containing a single key: host. Note that three keys have been added to the configuration array: read, write and sticky. After the database has been created, you may easily configure your environment variables to point to this database by placing the absolute path to the database in the DB_DATABASE environment variable: You can create a new SQLite database using the touch command in your terminal: touch database/database.sqlite.
