-----------------------------------
Summary: Add an Atomic Update Processor
Key: SOLR-9530
URL: https://issues.apache.org/jira/browse/SOLR-9530
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Varun Thacker
I'd like to explore the idea of adding a new update processor to help ingest
partial updates.
Example use-case - There are two datasets with a common id field. How can I
merge both of them at index time?
Proposed Solution:
{code}
<updateRequestProcessorChain name="atomic">
<processor class="solr.processor.AtomicUpdateProcessorFactory">
<str name="my_new_field">add</str>
</processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
{code}
So the first JSON dump could be ingested against
{{http://localhost:8983/solr/gettingstarted/update/json}}
And then the second JSON could be ingested against
{{http://localhost:8983/solr/gettingstarted/update/json?processor=atomic}}
The Atomic Update Processor could support all the atomic update operations
currently supported.
