---------------------------------------------
[~tledkov-gridgain] thanks for review, you are right, they not used mentioned
method, but all tests are ok, do you know additional tests i need to write for
reproduce this problem on certain implementations ? If no - i prefer to store
current implementation.
> Improper index usage, fields enumeration not used with pk index creation.

> Key: IGNITE-13280
> URL: https://issues.apache.org/jira/browse/IGNITE-13280
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 2.8.1
> Reporter: Stanilovsky Evgeny
> Assignee: Stanilovsky Evgeny
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> For example:
> {code:java}
> CREATE TABLE PUBLIC.TEST_TABLE (FIRST_NAME VARCHAR, LAST_NAME VARCHAR,
> ADDRESS VARCHAR, LANG VARCHAR, CONSTRAINT PK_PERSON PRIMARY KEY (FIRST_NAME,
> LAST_NAME));
> CREATE INDEX "idx2" ON PUBLIC.TEST_TABLE (LANG, ADDRESS);
> {code}
> and further explain:
> {code:java}
> SELECT
> "__Z0"."FIRST_NAME" AS "__C0_0",
> "__Z0"."LAST_NAME" AS "__C0_1",
> "__Z0"."ADDRESS" AS "__C0_2",
> "__Z0"."LANG" AS "__C0_3"
> FROM "PUBLIC"."TEST_TABLE" "__Z0"
> /* PUBLIC.IDX2: ADDRESS > 0 */
> WHERE "__Z0"."ADDRESS" > 0
> {code}
> this is erroneous to use "idx2" here, because first index field LANG not
> equals to predicate ADDRESS.
> Looks like this bug brings this ticket [1]
