[jira] [Created] (FLINK-26526) Record hasNull and allNull instead of nullCount in fieldStats

Caizhi Weng created FLINK-26526:
-----------------------------------

             Summary: Record hasNull and allNull instead of nullCount in fieldStats
                 Key: FLINK-26526
                 URL: https://issues.apache.org/jira/browse/FLINK-26526
             Project: Flink
          Issue Type: Sub-task
          Components: Table Store
    Affects Versions: 0.1.0
            Reporter: Caizhi Weng


Currently we aren't strongly relying on {{nullCount}}. Also, some formats (for example orc) does not support {{nullCount}} statistics. So we can record {{hasNull}} and {{allNull}} instead of {{nullCount}}.
