Defining Custom Key Space Name

The default key space name of WSO2 BAM server is EVENT_KS. By default, BAM persists data in EVENT_KS keyspace. For indexing purposes, another key-space is used by BAM. Default name for index key space is EVENT_INDEX_KS.

Both the default key space and index key space are referred by the <keySpaceName> element in <PRODUCT_HOME>/repository/conf/advanced/streamdefn.xml file as follows.

<StreamDefinition>
    <EventDatasourceName>WSO2BAM_CASSANDRA_DATASOURCE</EventDatasourceName>
    <EventIndexDatasourceName>WSO2BAM_CASSANDRA_EVENT_INDEX_SOURCE</EventIndexDatasourceName>
</StreamDefinition>

Changing the default key space name

You can define a different key space name for BAM persistence. It helps in physical separation of data, especially where the same cassandra cluster is used by multiple solutions/services. To change this, edit the <keySpace> element of the WSO2BAM_CASSANDRA_DATASOURCE in <PRODUCT_HOME>/repository/conf/datasources/bam-datasources.xml file as follows.

 <datasource>
            <name>WSO2BAM_CASSANDRA_DATASOURCE</name>
            <description>The datasource used for Cassandra data</description>
            <definition type="CASSANDRA">
                <configuration>
                    <keySpace>EVENT_KS</keySpace>
                </configuration>
            </definition>
        </datasource>

Changing the index key space name

To change the index key space name, edit the <keySpace> element of the WSO2BAM_CASSANDRA_EVENT_INDEX_SOURCE in <PRODUCT_HOME>/repository/conf/datasources/bam-datasources.xml file as follows.

<datasource>
            <name>WSO2BAM_CASSANDRA_EVENT_INDEX_SOURCE</name>
            <description>The datasource used for Cassandra data</description>
            <definition type="CASSANDRA">
                <configuration>
                    <keySpace>EVENT_INDEX_KS</keySpace>
                </configuration>
            </definition>
        </datasource>
