Method Detail

staticInit

public static void staticInit(CassandraProcessEngineConfiguration config)

This method is called after the session is initialized, but before the engine finished initializing. so it can be used for any initialization that requires cassandra session, but it should not use any camunda functionality

Parameters:

config -

selectList
