------------------------------------------

             Summary: Filter is not pushed to JDBC database when several databases are used in the query
                 Key: DRILL-7340
                 URL: https://issues.apache.org/jira/browse/DRILL-7340
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - JDBC
    Affects Versions: 1.16.0
            Reporter: Volodymyr Vysotskyi
             Fix For: Future


For the case when several databases are used in the query, some rules weren't added to the rule set for one of the conventions. It is observed in queries similar to the next query:
{code:sql}
select * from mysql.`drill_mysql_test`.person t1
INNER JOIN h2.drill_h2_test.person t2 on t1.person_id = t2.person_id where t1.first_name = 'first_name_1' and t2.last_name = 'last_name_1
{code}
Plan for this query is the following:
{noformat}
00-00    Screen
00-01      Project(person_id=[$0], first_name=[$1], last_name=[$2], address=[$3], city=[$4], state=[$5], zip=[$6], json=[$7], bigint_field=[$8], smallint_field=[$9], numeric_field=[$10], boolean_field=[$11], double_field=[$12], float_field=[$13], real_field=[$14], time_field=[$15], timestamp_field=[$16], date_field=[$17], datetime_field=[$18], year_field=[$19], text_field=[$20], tiny_text_field=[$21], medium_text_field=[$22], long_text_field=[$23], blob_field=[$24], bit_field=[$25], enum_field=[$26], PERSON_ID0=[$27], FIRST_NAME0=[$28], LAST_NAME0=[$29], ADDRESS0=[$30], CITY0=[$31], STATE0=[$32], ZIP0=[$33], JSON0=[$34], BIGINT_FIELD0=[$35], SMALLINT_FIELD0=[$36], NUMERIC_FIELD0=[$37], BOOLEAN_FIELD0=[$38], DOUBLE_FIELD0=[$39], FLOAT_FIELD0=[$40], REAL_FIELD0=[$41], TIME_FIELD0=[$42], TIMESTAMP_FIELD0=[$43], DATE_FIELD0=[$44], CLOB_FIELD=[$45])
00-02        HashJoin(condition=[=($0, $27)], joinType=[inner], semi-join: =[false])
00-03          Project(PERSON_ID0=[$0], FIRST_NAME0=[$1], LAST_NAME0=[$2], ADDRESS0=[$3], CITY0=[$4], STATE0=[$5], ZIP0=[$6], JSON0=[$7], BIGINT_FIELD0=[$8], SMALLINT_FIELD0=[$9], NUMERIC_FIELD0=[$10], BOOLEAN_FIELD0=[$11], DOUBLE_FIELD0=[$12], FLOAT_FIELD0=[$13], REAL_FIELD0=[$14], TIME_FIELD0=[$15], TIMESTAMP_FIELD0=[$16], DATE_FIELD0=[$17], CLOB_FIELD=[$18])
00-05            SelectionVectorRemover
00-06              Filter(condition=[=($2, 'last_name_1')])
00-07                Jdbc(sql=[SELECT * FROM "TMP"."DRILL_H2_TEST"."PERSON" ])
00-04          Jdbc(sql=[SELECT * FROM `drill_mysql_test`.`person` WHERE `first_name` = 'first_name_1' ])
{noformat}
{{DrillJdbcFilterRule}} wasn't applied for H2 convention and Filter wasn't pushed to H2 database.

This issue may be fixed by specifying {{JdbcConvention}} in rules descriptions in Drill {{DrillJdbcFilterRule}} and {{DrillJdbcProjectRule}} rules and other rules should be fixed in Calcite in the scope of CALCITE-3115.
