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)
