Pavel Tupitsyn updated IGNITE-4425:
-----------------------------------
    Description: 
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}
