What does solr support ? A Relational Data base or a NoSql DB's

Question

I would like to know weather SOLR supports a NoSql Database or a Relational Database?

Thanks

Are you asking about SOLR's data structure? Or are you asking if Solr can import from RDBMS/NoSQL? — Srikanth Venugopalan, Jul 02 '14 at 05:23
@SrikanthVenugopalan Yes. I am asking about SOLR's DataStructure. — Venkat, Jul 02 '14 at 12:52
@MauricioScheffer SOLR's Data model is like NoSQL just like Columnar Databases like HBase, Cassandra ? But SOLR has schema.xml which is similar to Rational DB? I am confused with this. — Venkat, Jul 02 '14 at 12:55

Solr internally uses Apache Lucene for indexing. Details about the index file structure is available in the docs here.

Technically this can be classified as a NoSQL store.

Thanks for the docs, appreciated. Is there any difference between Solr Segments and Lucene Segments. I think Solr internally uses Lucene's indexing and merging the segments. – Venkat Jul 07 '14 at 16:53
Sorry @Venkat - That is too much of an implementation detail for me, haven't bothered getting into that detail. You should try asking this on one of the Solr Mailing lists. – Srikanth Venugopalan Jul 08 '14 at 01:57
