I recommend that Ignite can implement a function using JSON Path to handle such 
ArrayList type.

Since most of RDBS supports JSON PATH now like MSSQL. It would be easier for 
developer to handle with nested object or JSON string.

Before Ignite implement this, developer have to implement a  customized 
function for it.

Subject: Re: LIKE operator on Array column in Apache ignite SQL

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.

BR,
Andrei
