Update Request Processor Chains

I am trying to understand update request processor chains. Do they runs one
by one when indexing a ducument? Can I identify multiple update request
processor chains? Also what are that LogUpdateProcessorFactory and
RunUpdateProcessorFactory?

You can have multiple update chains defined and use only one of them per update request.

LogUpdateProcessor logs the update request and the RunUpdateProcessor is where the actual index is updated.
