owencwl opened a new issue #3068:
URL: https://github.com/apache/iceberg/issues/3068
Why is the filter condition not effective？？？？？？and print out all the data
in the table.
I use hivecatalog and the file format is parquet.
Example code:
public static void main(String[] args) throws IOException {
String lakeSpaceName = "default";
String lakeTableName = "t";
TableIdentifier tableIdent = TableIdentifier.of(lakeSpaceName,
lakeTableName);
CatalogLoader hiveloader = CatalogLoader.hive(lakeSpaceName, hiveConf,
Maps.newHashMap());
TableLoader tableLoader = TableLoader.fromCatalog(hiveloader,
tableIdent);
List<RowData> results =
readRowData(FlinkSource.forRowData().tableLoader(tableLoader)
.filters(Collections.singletonList(Expressions.equal("dt",
"2020-03-29"))).buildFormat(),null);
results.forEach(System.out::println);
}
public static List<RowData> readRowData(FlinkInputFormat inputFormat,
RowType rowType)
throws IOException {
FlinkInputSplit[] splits = inputFormat.createInputSplits(0);
List<RowData> results = Lists.newArrayList();
for (FlinkInputSplit s : splits) {
inputFormat.open(s);
while (!inputFormat.reachedEnd()) {
RowData row = inputFormat.nextRecord(null);
results.add(row);
}
}
inputFormat.close();
return results;
}
