Hi Mikhail, I tried with a simplest zipper entity. Here are the config details-
<document name="sampleProperties"> <entity name="propertiesList" processor="SqlEntityProcessor" query="SELECT PROPERTY_ID FROM property order by PROPERTY_ID"> <field column="PROPERTY_ID" name="propertyId" /> <entity name="description" processor="SqlEntityProcessor" where="PROPERTY_ID='${propertiesList.PROPERTY_ID}'" query="SELECT * FROM property_text ORDER BY PROPERTY_ID" join="zipper"> <field column="TEXT" name="freeText" /> </entity> </entity> </document> Here child entity have multiple records for a given property id. Hence I believe full import is failing. I have added new logs below. Is there a way Zipper supports multiple records merge? aused by: java.lang.IllegalArgumentException: expect strictly increasing primary keys for Relation PROPERTY_ID='${propertiesList.PROPERTY_ID}' got: , at org.apache.solr.handler.dataimport.Zipper.onNewParent(Zipper.java:108) -- View this message in context: http://lucene.472066.n3.nabble.com/Getting-error-while-excuting-full-import-tp4329153p4330488.html Sent from the Solr - User mailing list archive at Nabble.com.
