[improvement](statistics)Eliminate null values while sample analyzing ndv. #50574

Jibing-Li · 2025-04-30T09:37:44Z

What problem does this PR solve?

Eliminate null values while sample analyzing ndv.
For example, if the values of col1 in table1 are all NULL, the ndv of col1 should be 0, not 1.
If ndv=0 and min/max not null and null_num == rowCount, we keep this stats info but set to unknown in stats calculator. This is probably because sampled an all-null tablet.

… ndv. (#50574) ### What problem does this PR solve? 1. Eliminate null values while sample analyzing ndv. For example, if the values of col1 in table1 are all NULL, the ndv of col1 should be 0, not 1. 2. If ndv=0 and min/max not null and null_num == rowCount, we keep this stats info but set to unknown in stats calculator. This is probably because sampled an all-null tablet.
