Subject Re: SolrCore as Singleton?
Date Thu, 07 Sep 2006 18:31:53 GMT

: Is there a good reason for implementing SolrCore as a Singleton?

I'm going to sidestep the issue of wether there *was* a good reason for
it, as well as the "does the singleton pattern make sense for the current
usage" question and answer what i think is an equally significant
question: "what are the implications of trying to change it now?" ... the
biggest i can think of being that SolrConfig is also a static singleton,
and a *lot* of code in the Solr code base would need to be changed to
support multiple SolrConfigs ... and without multiple SolrConfigs, there
really isnt' any reason to have multiple SolrCores.
