> In order increase the ability of Solr to be used as a NoSql database (lots of concurrent
inserts, updates, deletes and queries in the entire lifetime of the index) instead of just
a search index (first: everything indexed (in one thread), after: only queries), I would like
Solr to support the following features inspired by RDBMSs and other NoSql databases.
> * Given a solr-core with a schema containing a uniqueKey-field "uniqueField" and a document
Dold, when trying to INSERT a new document Dnew where Dold.uniqueField is equal to Dnew.uniqueField,
then I want a DocumentAlredyExists error. If no such document Dold exists I want Dnew indexed
into the solr-core.
> * Given a solr-core with a schema containing a uniqueKey-field "uniqueField" and a document
Dold, when trying to UPDATE a document Dnew where Dold.uniqueField is equal to Dnew.uniqueField
I want Dold deleted from and Dnew added to the index (just as it is today).If no such document
Dold exists I want nothing to happen (Dnew is not added to the index)
