Hi all,
I've started to work on a couple of components very tight together.
An update processor that writes few fields in the solr index and a Query
Parser that, well, then reads such fields from the index.
Such components share few configuration parameters together, I'm asking if
there is a pattern, a draft, a sample, some guidelines or best practices
that explains how to properly save configuration parameters.
The configuration is written into the solrconfig.xml file, for example:
<processor class="com.example.MyCustomProcessorFactory" >
<lst name="name">
<str name="n1">x1</str>
<str name="n2">x2</str>
</lst>
</processor>
And then query parser :
<queryParser name="myqp"
class="com.example.query.MyCustomQueryParserPlugin" />
I'm struggling because the change of configuration on the updated processor
has an impact on the query parser.
For example the configuration info shared between those two components can
be overwritten during a core reload.
Basically, during an update or a core reload, there is a query parser that
is serving requests while some other component is updating the index.
So I suppose there should be a pattern, an approach, a common solution when
a piece of configuration has to be loaded at boot, or when the core is
loaded.
Or when, after an update a new searcher is created and a new query parser
is created.
Any suggestion is really appreciated.
Best regards,
Vincenzo
