/db/feeding/feedingBatch Definition of one batch to Solr (currently supported types: add, delete)
   /idColumn Column in sql which holds Solr primary key
   /mainSelect sql query representing the batch data (it is advised be ordered by column defined in timestamps)
   /columnMap sql data mappings
     /map Mapping is mainly used for separating values for Solr multi-valued field
       @src column in row from database, which should be mapped (mapped columns will NOT be send to Solr, unless they appear in dst too)
       @dst field name in Solr document
       @separator [OPTIONAL] separator for data in src (if it is not set, mapping will simply pass the value)
/feeder/solr
  /url Solr collection url
  /readTimeout Timeout for Solr client
  /batchSizeDocs Max number of documents send to Solr in one batch
