update operation
Ishan Chattopadhyaya created SOLR-11267:
-------------------------------------------
Summary: Add support for "add-distinct" atomic update operation
Key: SOLR-11267
URL: https://issues.apache.org/jira/browse/SOLR-11267
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Ishan Chattopadhyaya
Often, a multivalued field is used as a set of values. Since multivalued fields are more like lists than sets, users do two consecutive operations, remove and add, to insert an element into the field and also maintain the set's property of only having unique elements.
Proposing a new single operation, called "add-distinct" (which essentially means "add-if-doesn't exist") for this.
