[jira] [Commented] (STANBOL-353) Make the RESTful API internally Managed SolrCores available via the Stanbol http endpoint

["Rupert Westenthaler (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STANBOL-353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13145316#comment-13145316 ] 

Rupert Westenthaler commented on STANBOL-353:
---------------------------------------------

As of #1195450 the RESTful interface of Solr CoreContainer can be mapped to the HttpService of the OSGI environment by the use of a special variant (subclass) of the SolrDispatchFilter that uses the CoreContainer registered as OSGI servie instead of initializing a new one on the initialisation of the Filter (as it is the case for the std. SolrDispatchFilter).

Currently a OSGI component is provided that can be used to publish CoreContainers on a configured path. In future there will be also the possibility to publish CoreContainer "automatically" under a configurable global prefix (e.g. "/solr") without the need of any further configuration.
This auto-publish feature can be (de)activated by a boolean property in the metadata of the service registration for a CoreContainer.

CoreContainers published this way will be available under

    {globalPrefix}/{coreContainer-name}/{solrCore-name}/select?q=test

> Currently SolrCors managed by the org.apache.commons.solr module are only exposed as EmbeddedSolrServer. There is no possibility to access such SolrCores via the typical RESTful API.
> This will include two improvements:
> (1) provide a Default JAX-RS resource that publishes all internally managed SolrCores at a specified Path.
> Also add a configuration that allows to enable/disable this feature.
> (2) provide a base implementation of a JAX-RS resource that allows to publish the RESTful API of a specific SolrCore.
> This is intended to be used by Modules that internally manage a SolrCore and want to have the RESTful API of the SolrServer to be available at a specific path or even to intercept calls (e.g. to do some preprocessing) before sending them to the SolrCore.
> For the implementation of this one needs something like org.apache.solr.servlet.SolrDispatchFilter but more flexible and configurable e.g.
> * allow only some core (e.g. cores that are configured to be published as RESTful service) - needed for (1)
> * allow initialization for a specific core - needed for (2)
> * allow to restrict the allowed RequestHandler (e.g. to disallow Admin Requests to prevent reconfiguration of the Solr via the RESTful API)
> In addition features already provided by JAX-RS should be also used by such an implementation.
