[jira] [Created] (SOLR-3318) LBHttpSolrServer should allow to
specify a preferred server for a query
LBHttpSolrServer should allow to specify a preferred server for a query
-----------------------------------------------------------------------
Key: SOLR-3318
URL: https://issues.apache.org/jira/browse/SOLR-3318
Project: Solr
Issue Type: Improvement
Components: clients - java
Affects Versions: 4.0
Reporter: Martin Grotzke
Priority: Minor
For a user query we make several solr queries that differ only slightly and therefore should use/reuse objects cached from the first query (we're using a custom request handler and custom caches).
Thus such subsequent queries should hit the same solr server.
The implemented solution looks like this:
* The client obtains a live SolrServer from LBHttpSolrServer
* The client provides this SolrServer as preferred server for a query
* If the preferred server is no longer alive the request is retried on another live server
* Everything else follows the existing logic:
** After live servers are exhausted, any servers previously marked as dead will be tried before failing the request
** If no live servers are found a SolrServerException is thrown
The implementation is also [on github|https://github.com/magro/lucene-solr/commit/a75aef3d].

[jira] [Commented] (SOLR-3318) LBHttpSolrServer should allow to

-------------------------------------------
+1 on this one. To construct a response we run 2 solr queries, one for results one for facets. For caching purpuses it would be perfect to run those consecutive one on the same solr instance
