Subject [jira] [Created] (SOLR-2841) Scriptable UpdateRequestChain
Date Sun, 16 Oct 2011 13:00:12 GMT
Scriptable UpdateRequestChain
-----------------------------

                 Key: SOLR-2841
                 URL: https://issues.apache.org/jira/browse/SOLR-2841
             Project: Solr
          Issue Type: New Feature
          Components: update
            Reporter: Jan Høydahl


UpdateProcessorChains must currently be defined with XML in solrconfig.xml. We should explore
a scriptable chain implementation with a DSL that allows for full flexibility. The first step
would be to make UpdateChain implementations pluggable in solrconfig.xml, for backward compat
support.

Benefits and possibilities with a Scriptable UpdateChain:
* A compact DSL for defining Processors and Chains (Workflows would be a better, less limited
term here)
* Keeping update processor config separate from solrconfig.xml gives better separations of
roles
* Use this as an opportunity to natively support scripting language Processors (ideas from
SOLR-1725)

This issue is spun off from SOLR-2823.
