Noble Paul commented on SOLR-969:
---------------------------------
All the Objects can be consumed directly from JS , just the way we use it in
java .
example
{code}
<dataConfig>
<script><![CDATA[
function f1(row, context) {
var cmd =
context.getVariableResolver().replaceTokens('${dataimporter.request.command}');
if(cmd == 'full-import')
row.put('message', 'The command is full-import');
return row;
}
]]></script>
<document>
<entity name="e" pk="id" transformer="script:f1" query="select
* from X">
....
</entity>
</document>
</dataConfig>
{code}
Currently only a Transformer can be written in JS and that is the most common
extension point.
It is hard to write a DataSource/EntityProcessor in JS . I'm interested in
having an Entityprocessor written in non-java. but there has not been much
interest in it.
an Eventlistener can be easily written in JS (but not yet implemented)
