Hi All! We are using: org.apache.flink:flink-table_2.11:jar:1.4.2:compile
SELECT COALESCE(user_id, -1) AS user_id, count(id) AS count_per_window, sum(amount) AS charge_amount_per_window, TUMBLE_START(rowtime, INTERVAL '2' YEAR) AS twindow_start, TUMBLE_END(rowtime, INTERVAL '2' YEAR) AS twindow_end FROM event_charge_processed WHERE capture=true AND COALESCE(user_id, -1) <> -1 GROUP BY TUMBLE(rowtime, INTERVAL '2' YEAR), COALESCE(user_id, -1) For '1' MONTH intervals it results in 1ms windows, 2 MONTH=2ms, 3 MONTH=3ms …. 1 YEAR=12ms, 2 YEAR=24ms! Which results in incorrect aggregations. I found that org.apache.calcite.sql.SqlLiteral#getValueAs() treats MONTH/YEAR differently than DAY/HOUR etc. Perhaps the bug is somewhere there (?). Is this a known issue? Has it been fixed in later versions? Thanks, Vinod
