Subject [jira] Commented: (SOLR-1395) Integrate Katta
Date Sat, 12 Feb 2011 02:03:57 GMT


tom liu commented on SOLR-1395:

 the request and response are transfered between those commponents:
 # one tomcat webapp, which is the frontserver before Katta-Integrated-Solr
 # kattaclient, which runs on tomcat webapp, and dispatch requestes to KattaCluster with RPC
 # KattaCluster Node, which handles contentserver(ISolrServer), and RPC server
 # ISolrServer, which recv request, and dispatch request to SolrCore
 # SolrCore, which is EmbeddedSolrServer, and returns response from request

 so, queryComponent return the DocSlice, but with EmbeddedSolrServer, the DocSlice is casted
to SolrDocumentList.

 i attached one JPG file, which shows some commponents deployed.

 with katta, there are two deployments:
 # app deployment: deploy commponents, and startup
 # data deployment: use katta script to deploy data, for example, addIndex/removeIndex/redeployIndex
