Subject [jira] [Created] (SOLR-3173) Database semantics - insert and update
Date Tue, 28 Feb 2012 14:39:46 GMT
Database semantics - insert and update
--------------------------------------

                 Key: SOLR-3173
                 URL: https://issues.apache.org/jira/browse/SOLR-3173
             Project: Solr
          Issue Type: New Feature
          Components: update
    Affects Versions: 3.5
         Environment: All
            Reporter: Per Steffensen
             Fix For: 4.0


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)
