I am trying to use the DocExpirationUpdateProcessorFactoryfactory in Solr 4.10.1 version.
I have included the following in my solrconfig.xml <updateRequestProcessorChain default="true"> <processor class="solr.UUIDUpdateProcessorFactory"> <str name="fieldName">id</str> </processor> <processor class="solr.TimestampUpdateProcessorFactory"> <str name="fieldName">timestamp</str> </processor> <processor class="solr.processor.DocExpirationUpdateProcessorFactory"> <int name="autoDeletePeriodSeconds">30</int> <str name="ttlFieldName">ttl</str> <str name="expirationFieldName">expire_at</str> </processor> <processor class="solr.LogUpdateProcessorFactory" /> <processor class="solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> And I have included the following in my schema.xml <field name="timestamp" type="date" indexed="true" stored="true" default="NOW" multiValued="false"/> <field name="ttl" type="date" indexed="true" stored="true" default="NOW+60SECONDS" multiValued="false"/> <field name="expire_at" type="date" indexed="true" stored="true" multiValued="false"/> As you can see I am setting the time to live to be 60 seconds and checking to delete every 30 seconds, when I insert a document , and check after a minute or couple or an hour it never gets deleted. This is what I see in the indexed document , can you please let me know what might be the issue here ? Please note that the expire_at field is never getting generated in the Solr document as can be seen below. "id": "3888a8ac-fbc4-437a-8248-132384753c00", "timestamp": "2015-02-04T04:09:21.29Z", "_version_": 1492147724740460500, "ttl": "2015-02-04T04:10:21.29Z"
