Automatically Integrate with RDBMSs
Apache Ignite® provides support for integrating with a variety of persistence stores. It allows you to connect to the database, import schemas, configure indexed types, and automatically generate all the required XML OR-mapping configuration and Java domain model POJOs that you can easily download and copy into your project.
Ignite can integrate with any relational database (RDBMS) that supports a JDBC driver - Oracle, PostgreSQL, Microsoft SQL Server, and MySQL.
RDBMS Integration Wizard
Ignite supports automatic RDBMS integration via Ignite Web Console which is an interactive configuration wizard, management and monitoring tool that allows you to:
- Create and download various configurations for your Ignite cluster.
- Automatically construct Ignite's SQL metadata from any RDBMS schemas.
- Execute SQL queries over your in-memory caches.
- View query execution plans, in-memory schemas and streaming charts.
Ignite Web Console is an innovative tool that offers plenty of rich functionalities to manage the Ignite cluster and is not limited to features mentioned above.
Example
Here is an example of automatically generated Person class, as well as Java and XML configurations, imported from a MySQL PERSON table via Ignite Web Console.
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
...
<property name="cacheStoreFactory">
<bean class="org.apache.ignite.cache.store.jdbc.CacheJdbcPojoStoreFactory">
<property name="dataSourceBean" value="dsMySQL"/>
<property name="dialect">

</property>
<property name="types">
<list>
<bean class="org.apache.ignite.cache.store.jdbc.JdbcType">
<property name="cacheName" value="PersonCache"/>
<property name="keyType" value="java.lang.Integer"/>
<property name="valueType" value="com.apache.ignite.myexample.model.Person"/>
