spaces-X opened a new issue #6452:
URL: https://github.com/apache/incubator-doris/issues/6452
Multi-rollups may hold the same Ref of bitmap_value object in spark load
etl job, which will cause the bitmap to be updated repeatedly.
For example, the baseIndex and Rollups are as follows.
- baseIndex
- R1
- R2
- R3
In this situation, R1 will be calculated based on baseIndex and meanwhile
unfortunately bitmap value object holded by baseIndex may be updated. Then the
result of R2 , which is calculated based on baseIndex, will be incorrect
because the base index has been modified by R1.
To avoid the above situation, it is supposed to do a deep copy of bitmap
value object in the operator `or` function.
