How many UpdateHandlers can a Solr config have?

[Julian Heise <ju...@gmx.net>]

Hello everyone,

 

just a very basic question, but I haven't been able to find the answer in
the Solr wiki: how many updateHandlers can one Solr config have? Just one?
Or many?

 

Thank you very much

There can only be one <updateHandler /> declaration in solrconfig.xml, 
it's 
responsible for "owning" updates to the index.

But there can be any number of <requestHandler /> declarations to 
configure request handlers that do updates, as well as any number of 
<updateRequestProcessorChain /> declarations that can identify the 
processors used for dealing with updates (which cna be refered to by name 
from the request handlers)
