All events within the replication stream contain metadata about each
event. This information can be individually processed and manipulated. The
dropmetadata filter removes specific
metadata from each event, configured through the
option parameter to the filter.

Metadata information can be processed at the event top-level:
metaData = event.getDBMSEvent().getMetadata();
for(m = 0; m < metaData.size(); m++)
{
option = metaData.get(m);
if(option.getOptionName().compareTo(optionName)==0)
{
metaData.remove(m);
break;
}
}
