| <description> |
| If hive.auto.convert.sortmerge.join is set to true, and a join was converted to a sort-merge join, |
| this parameter decides whether each table should be tried as a big table, and effectively a map-join should be |
| tried. That would create a conditional task with n+1 children for a n-way join (1 child for each table as the |
| big table), and the backup task will be the sort-merge join. In some cases, a map-join would be faster than a |
| sort-merge join, if there is no advantage of having the output bucketed and sorted. For example, if a very big sorted |
| and bucketed table with few files (say 10 files) are being joined with a very small sorter and bucketed table |
| with few files (10 files), the sort-merge join will only use 10 mappers, and a simple map-only join might be faster |
| if the complete small table can fit in memory, and a map-join can be performed. |
