>Does setting index of cache configuration solves the column Groupid not found problem.
yes, it does. >Cause I am not setting fields explicitly in QueryEntity. Is it required to set fields in QueryEntity when annotations are used in Pojo? you must choose only one approach to describe an object for indexing: 1. Annotations 2. QueryEntity if you choose QueryEntity, you will need to describe object fields according to documentation I provided above. Thanks, Mike. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
