Subject [jira] [Commented] (SOLR-4086) Refactor DIH - VariableResolver & Evaluator
Date Thu, 20 Dec 2012 09:05:12 GMT


Dominik Siebel commented on SOLR-4086:

Hi James,

thanks for the quick reply.
I will have to check if company policy allows to post our data-config xmls in a public issue
tracker, but I can say that much:

our data-configs mainly consist of nested entities using variables to access the parent scope
and also using the ${dataimporter.function.escapeSql()} function to strip unwanted characters.
Nothing more ( no DateFormatEvaluator, at least not explicitly ).
The query results of the root entity are post-processed via ScriptTransformer.

The JVM is
* Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM (1.6.0_37 20.12-b01)

Configured with
* -d64
* -Xms8g
* -Xmx8g
* -XX:+CMSParallelRemarkEnabled
* -XX:+UseConcMarkSweepGC
* -XX:+UseParNewGC

With cores
* main (~17G)

> This simplifies VariableResolver and moves each built-in Evaluator into its own class.
 Compiler warnings / missing generics are fixed.  Also, the Locale bug with DateFormatEvaluator
is solved.  Instead of using the machine default, the Root Locale is used by default.  An
optional 3rd parameter allows users to specify whatever locale they want.
