Hi, Ignite SQL engine supports only the next types:
https://apacheignite-sql.readme.io/docs/data-types Also all existed functions you can see here: https://apacheignite-sql.readme.io/docs/sql-reference-overview So there is no way to work with arrays as DataTypes even if you set them as type in QueryEntity. Possible that you can add some new boolean SQL fields to the object that contains the array: public class Market{ @QuerySqlField(index = true) private java.lang.String id; @QuerySqlField private java.lang.Boolean isContainLacl; @QuerySqlField private ArrayList<String> array; select * from market where isContainLacl = true; You can fill this boolean flag when generating the Market object.
