Hi,
The reason for deprecation is that SqlQuery is a limited subset of
SqlFieldsQuery, which may be confusing.

I found the link how to read full object. But would still like to
understand why SqlQuery is deprecated.

Hi,
With Ignite 2.9 or before Ignite supported SqlQuery but in 2.11 I
see it is deprecated. Could you please tell us why and what is the
alternative to it. SqlFieldQuery does not allow to read full
object like below but individual fields which is cumbersome
String sql1 = "select * from Person";
cache.query(new SqlQuery<LocalDateTime, Person>(Person.class,
sql1))
.getAll()
.forEach(e ->System.out.println("Value: "+ e.getValue()));
