> SQL supports IN queries and, as a better alternative, temporary table join, as described in the docs:
> https://apacheignite.readme.io/docs/sql-performance-and-debugging#sql-performance-and-usability-considerations
> Example SQL:
> {code}
> new SqlFieldsQuery("select p.name from Person p join table(id bigint = ?) i on p.OrgId = i.id", new object[] { new object[] {1,3}})
> {code}
> Add support in LINQ like this:
> {code}
> persons.AsCacheQueryable().Where(x => new[] {1,3}.Contains(x.Value.OrgId))
> {code}
