gojumprope opened a new issue, #17184: URL: https://github.com/apache/doris/issues/17184
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version 1.2.1 ### What's Wrong? I have table A with 323 rows data, table B with 96 rows data. select * from table A (278 ms) select * from table B (275 ms) I want to make each rows in table A to have all of the table B data, the final outcome will be 323 * 96 = 31008 rows select * from table A cross join table B but the query takes more than 30 seconds to load all the data ### What You Expected? cross join data should load faster, query only 30k data should load within 1 second. I have try using left join on 1=1, its speed even faster than cross join select * from area_test left join table_15_minute_test on 1 = 1 ### How to Reproduce? CREATE TABLE `area_test` ( `id` bigint, `childid` bigint ) DISTRIBUTED BY HASH(id) BUCKETS 32 PROPERTIES ( "replication_allocation" = "tag.location.default: 1" ); INSERT INTO area_test VALUES (645,637), (645,640), (646,637), (646,640), (647,637), (647,640), (648,637), (648,640), (649,637), (649,640), (650,637), (650,640), (651,637), (651,640), (652,637), (652,640), (653,637), (653,640), (654,637), (654,640), (656,637), (656,640), (657,637), (657,640), (658,637), (658,640), (659,637), (659,640), (660,637), (660,640), (661,637), (661,640), (662,637), (662,640), (663,637), (663,640), (664,637), (664,640), (665,637), (665,640), (666,637), (666,640), (667,637), (667,640), (670,639), (670,640), (670,641), (671,639), (671,640), (671,641), (672,639), (672,640), (672,641), (673,639), (673,640), (673,641), (675,639), (675,640), (675,641), (676,638), (676,640), (676,642), (677,638), (677,640), (677,642), (678,638), (678,640), (678,642), (679,638), (679,640), (679,642), (680,638), (680,640), (680,642), (681,638), (681,640), (681,642), (682,638), (682,640), (682,642), (683,638), (683,640), (683,642), (684,638), (684,640), (684,642), (685,638), (685,640), (685,642), (686,638), (686,640), (686,642), (687,638), (687,640), (687,642), (690,638), (690,640), (690,642), (692,638), (692,640), (692,642), (693,638), (693,640), (693,642), (694,638), (694,640), (694,642), (695,638), (695,640), (695,642), (696,638), (696,640), (696,642), (697,638), (697,640), (697,642), (698,638), (698,640), (698,642), (699,638), (699,640), (699,642), (700,638), (700,640), (700,642), (701,638), (701,640), (701,642), (702,638), (702,640), (702,642), (703,638), (703,640), (703,642), (704,638), (704,640), (704,642), (705,638), (705,640), (705,642), (706,638), (706,640), (706,642), (707,638), (707,640), (707,642), (708,638), (708,640), (708,642), (709,638), (709,640), (709,642), (710,638), (710,640), (710,642), (711,638), (711,640), (711,642), (712,638), (712,640), (712,643), (713,638), (713,640), (713,643), (714,638), (714,640), (714,643), (716,638), (716,640), (716,643), (718,638), (718,640), (718,643), (719,638), (719,640), (719,643), (720,638), (720,640), (720,643), (721,638), (721,640), (721,643), (722,638), (722,640), (722,643), (725,638), (725,640), (725,643), (726,638), (726,640), (726,643), (727,638), (727,640), (727,643), (728,638), (728,640), (728,643), (729,638), (729,640), (729,643), (730,638), (730,640), (730,643), (731,638), (731,640), (731,643), (733,638), (733,640), (733,643), (734,638), (734,640), (734,643), (735,638), (735,640), (735,643), (737,638), (737,640), (737,643), (738,638), (738,640), (738,643), (739,638), (739,640), (739,643), (740,638), (740,640), (740,643), (741,638), (741,640), (741,644), (744,638), (744,640), (744,644), (745,638), (745,640), (745,644), (746,638), (746,640), (746,644), (747,638), (747,640), (747,644), (748,638), (748,640), (748,644), (749,638), (749,640), (749,644), (750,638), (750,640), (750,644), (751,638), (751,640), (751,644), (752,638), (752,640), (752,644), (753,638), (753,640), (753,644), (754,638), (754,640), (754,644), (755,638), (755,640), (755,644), (756,638), (756,640), (756,644), (757,638), (757,640), (757,644), (758,638), (758,640), (758,644), (759,638), (759,640), (759,644), (761,638), (761,640), (761,644), (762,638), (762,640), (762,644), (763,638), (763,640), (763,644), (764,638), (764,640), (764,644), (766,639), (766,640), (768,639), (768,640), (776,812), (779,638), (779,640), (779,643), (780,638), (780,640), (780,643), (781,638), (781,640), (781,643), (782,639), (782,640), (782,641), (783,638), (783,640), (783,644), (785,638), (785,640), (785,644), (787,639), (787,640), (788,638), (788,640), (788,643), (811,639), (811,640), (813,638), (813,640), (813,643) CREATE TABLE `table_15_minute_test` ( `__time` datetime ) DISTRIBUTED BY HASH(__time) BUCKETS 32 PROPERTIES ( "replication_allocation" = "tag.location.default: 1" );
