xuefuz commented on issue #10380: [FLINK-14662]Distinguish unknown 
CatalogTableStatistics and zero
URL: https://github.com/apache/flink/pull/10380#issuecomment-561779941
 
 
   Thanks to @zjuwangg for the update. I think the potential problems still 
exists:
   1. Hive uses 0 as unknown, which Flink might think no data.
   2. -1 may still cause issues even though nothing surfaced in our experiment.
   #1 is a bigger issue. To mitigate it, we can recommend user to keep the 
stats updated always. For now, I think we just need to keep an eye on this 
issue.
