Livia updated IGNITE-21246:
---------------------------
Description:
Hi,
When I use Ignite as an SQL database,
There are 3 tables to left join, but the result is abnormal.
There is only one Ignite server node, and persistence is enabled.
I use PARTITIONED mode to create SQL tables, then I execute a join query in a
non-colocated mode ({_}jdbc:ignite:thin://localhost;distributedJoins=true{_}).
But I got an error prompting a lack of index for the table STUDENT_COURSE.
The documentation suggests that a replicated table needs a column index, but
these are PARTITIONED tables.
_If you use a non-collocated join on a column from a [replicated
table|https://ignite.apache.org/docs/2.11.1/data-modeling/data-partitioning#replicated],
the column must have an index. Otherwise, you will get an exception._
Okay, I create indexs for it. Then I execute the query again. I expect 6 rows,
but actually, only 1 row is returned.
A more unusual situation arises when I add a WHERE condition to the query. The
result is correct.

The detailed commands are as follows:
