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

             Summary: ParquetIO.read(): data loss with FilterPredicate
                 Key: BEAM-13104
                 URL: https://issues.apache.org/jira/browse/BEAM-13104
             Project: Beam
          Issue Type: Bug
          Components: io-java-parquet
            Reporter: Alexey Romanenko


If {{ParquetIO.read()}} is used with {{withConfiguration()}} and {{FilterPredicate}}, and filtered records are not the beginning of the reading block then they will be skipped and it will cause a data loss.
