The default key space name of the WSO2 BAM server is EVENT_KS. By default, BAM persists data in EVENT_KS keyspace but you . 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.

Changing the default key space name
You can define a different keyspace 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....
For indexing purposes, another key-space is used by BAM. Default name for index key-space is EVENT_INDEX_KS.
