Subject [jira] [Commented] (SOLR-2841) Scriptable UpdateRequestChain
Date Thu, 22 Dec 2011 10:30:30 GMT


Chris Male commented on SOLR-2841:

bq. Another use case for scripting at the top level is "multi-query" queries: where the app
creates the second based on the first. Would your proposal handle this problem?

So you mean having scriptable query time logic? That seems a pretty scary thing to get into.

> 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.
