This script handles the import from mongoDB documents to solr/lucene lucene in order to index mongoDB data in solr/lucene. It was initial designed for midrange (and above) sized mongoDBs, so block processing, multi-threading (to use all CPU cores), solr cores and mongoDB replication sets are supported. The script collets the documents from mongoDB, performs some converting or field mapping, if this is required and index/store those documents to Solr.
You need an activated PCNTL module, if you like to use the "multi threaded" future. Otherwise use the option -s true to run the single thread version.
This script needs an PHP installation (tested on 5.3.8).
Just copy the script and config file to your system and edit the configuration for your environment.
Index your mongoDB documents to solr by running that following command on system console:
user@system>php mongoSolrImporter.php -c mongoSolrImporter.ini
If you like (or need) to run in single thread use the option -s true
user@system>php mongoSolrImporter.php -c mongoSolrImporter.ini -s true
At this time of development, the mongoDB - Solr - Importer only supports flat mongo documents without embedded docs or arrays.
