My understanding is that the DIH in solr only enters last_indexed_time in dataimport.properties, but not say last_indexed_id for a primary key 'id'. How can I efficiently get the max(id) (note that 'id' is an auto-increment field in the database) ? Maintaining max(id) outside of solr is brittle and calling max(id) before each dataimport can take several minutes when the index has several hundred million records.
How can I either import based on ID or get max(id) quickly? I can not use timestamp-based import because I get out-of-memory errors if/when solr falls behind and the suggested fixes online did not work for me. -- View this message in context: http://lucene.472066.n3.nabble.com/DataImport-using-last-indexed-id-or-getting-max-id-quickly-tp3993763.html Sent from the Solr - User mailing list archive at Nabble.com.
