| <h1 id="working-with-kapua-database">Working with Kapua database</h1> |
| <p>In current implementation of Kapua we hold device data in SQL database (it can MariaDB or H2 SQL Server). In order to keep SQL schema updated, |
| we decided to use <a href="https://www.liquibase.org/" target="_blank">Liquibase</a>.</p> |
| <h2 id="liquibase-in-kapua">Liquibase in Kapua</h2> |
| <p>Kapua broker on startup executes embedded Liquibase client which ensures that all database update scripts have been collected and |
| applied to your database. The coordinates of database URL connection are obtained from regular Kapua settings i.e. the following |
| system properties:</p> |
| <ul> |
| <li><code>commons.db.username</code></li> |
| <li><code>commons.db.password</code></li> |
| <li><code>commons.db.schema</code></li> |
| </ul> |
| <p>Liquibase clients looks up for all scripts located in the classpath matching <code>liquibase/*.sql</code> pattern.</p> |
| <h3 id="adding-new-sql-script-to-the-project">Adding new SQL script to the project</h3> |
| <p>If you would like a new SQL script to your service, just add new <code>*.sql</code> file to <code>src/main/resources/liquibase</code> directory of your Maven project. Just keep in mind that |
| the name of your file should be unique, so the best way is to make it matching the name of your service module (for example <code>device.sql</code> for device management).</p> |
| <h3 id="adding-a-new-change-set-to-existing-sql-file">Adding a new change set to existing SQL file</h3> |
| <p>If you would like to add new change set to existing SQL file, append new <code>--changeset filename:number</code> line to your log file. The example:</p> |
| <pre><code>--changeset device_event:2 |
| |
| CREATE TABLE my_new_table ( |
| scope_id BIGINT(21) UNSIGNED NOT NULL |
| PRIMARY KEY (scope_id, id) |
| ) CHARSET=utf8; |
| </code></pre><p>More details regarding Liquibase SQL file syntax, can be found on <a href="http://www.liquibase.org/documentation/sql_format.html" target="_blank">Liquibase web page</a>.</p> |
