Description

SCR-20230220-ich

When benchmarking q101 and also q103, it seems compaction has a large effect on stream processing,
i.e. the CPU usage/throughput when compaction + computation < the CPU usage/throughput when only computation.

the impact of block cache invalidation is bigger than what we saw in other queries

Feel free to reassign, thanks!
