----------------------------------

             Summary: Revise the description watermark strategy in Flink Table document
                 Key: FLINK-19094
                 URL: https://issues.apache.org/jira/browse/FLINK-19094
             Project: Flink
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.11.0, 1.10.0
            Reporter: Leonard Xu
             Fix For: 1.12.0, 1.11.2, 1.10.3


The description of watermark strategy is wrong in doc[1]
 * Strictly ascending timestamps: {{WATERMARK FOR rowtime_column AS rowtime_column}}.

Emits a watermark of the maximum observed timestamp so far. -Rows that have a timestamp smaller to the max timestamp are not late.-
 * Ascending timestamps: {{WATERMARK FOR rowtime_column AS rowtime_column - INTERVAL '0.001' SECOND}}.
 Emits a watermark of the maximum observed timestamp so far minus 1. -Rows that have a timestamp equal and smaller to the max timestamp are not late.-
