David Smiley commented on SOLR-1725:
------------------------------------
+1 to Erik's proposal of streamlining the common case of needing just
processAdd() -- I shouldn't be required to even define a processAdd() method in
my script for this common case. I'd rather not have subclasses for this.
Perhaps the configuration in solrconfig for this processor would have a
processAddScript="myscript.rb" and a processDeleteScript= ... etc. as an
alternative to script="script.rb" -- if you use the one-file script then you
are required to define each method. And, how about if
scriptMethods="processAdd,processCommit" then you just need to define the ones
you list.
Like Erik, I too have been following the awesome progress here as of late --
thanks for your hard work Hoss (and Erik before him). It has come far.

> A script based UpdateRequestProcessorFactory (Uses JDK6 script engine
> support). The main goal of this plugin is to be able to configure/write
> update processors without the need to write and package Java code.
> The update request processor factory enables writing update processors in
> scripts located in {{solr.solr.home}} directory. The functory accepts one
> (mandatory) configuration parameter named {{scripts}} which accepts a
> comma-separated list of file names. It will look for these files under the
> {{conf}} directory in solr home. When multiple scripts are defined, their
> execution order is defined by the lexicographical order of the script file
> name (so {{scriptA.js}} will be executed before {{scriptB.js}}).
> The script language is resolved based on the script file extension (that is,
> a *.js files will be treated as a JavaScript script), therefore an extension
> is mandatory.
> Each script file is expected to have one or more methods with the same
> signature as the methods in the {{UpdateRequestProcessor}} interface. It is
> *not* required to define all methods, only those hat are required by the
> processing logic.
> The following variables are define as global variables for each script:
> * {{req}} - The SolrQueryRequest
> * {{rsp}}- The SolrQueryResponse
> * {{logger}} - A logger that can be used for logging purposes in the script
