Introduction

The Apache iBatis Data Mapper framework makes it easier to use a database with Java and .NET applications.

iBatis allows lazy loading. When enabled, a pojo object returned from a iBatis query will contain a proxy object to the referenced object. For instance, a Customer object returned from a query to the Customer table will have a proxy object in its reference to the Account object. iBatis will de-reference the proxy object when the Account object is queried at a later point in time.

With the Terracotta integration module for iBatis, one node can query a Customer table lazily and share the returned Customer object, while a second node can de-reference the Account object reference and obtain the referenced Account object.

Dependencies

None.

Implementation

To enable clustering with iBatis, add the iBatis configuration module to tc-config.xml:

<modules>
    <module name="clustered-iBatis-<iBatis_version>" version="<module_version>"/>
</modules>

For example, use the module clustered-iBatis-2.2.0-2.6.0, add the following snippet to tc-config.xml:

<modules>
    <module name="clustered-iBatis-2.2.0" version="2.6.0"/>
</modules>

Known Issues

None.
