rows from BigTable2 in the above statement, so we have chosen a nested loop, Scan BigTable2 to get the data in turn.For Nested loop join operators, you can refer to my second article.We know that this is the number of loops on the outside, which means that there are 4 threads executing nested loops in parallel. If the threads of each line is 25 rows, the internal table will be executed.4*25=100 times.Then, after the nested scan gets the results, the next step is to summarize the results of each
