Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The following page has been changed by ShalinMangar: http://wiki.apache.org/solr/DataImportHandler New page: = Overview = == Motivation == Most applications store data in relational databases and searching over such data is a common use-case. However, there is no standard way to import this data into SOLR index requiring custom tools external to SOLR. == Goals == * Read data residing in relational databases * Build SOLR documents by aggregating data from multiple columns and tables according to configuration * Update SOLR with such documents * Provide ability to do full imports according to configuration * Detect inserts/update deltas (changes) and do delta imports (we assume a last-modified timestamp column for this to work) * Schedule full imports and delta imports = Design Overview = As the name suggests, this is implemented as a SolrRequestHandler. The configuration is provided in two places: * solrconfig.xml (DataSource information is read from here e.g. JDBC Driver, JDBC URL, Username, Password etc.) * data-config.xml (DB Table/column to SOLR document mapping comes here) = Usage = TODO ---- CategorySolrRequestHandler
