This is the data to reproduce https://github.com/apache/arrow/issues/43745. The parquet file is generated with this script ``` import org.apache.hadoop.fs.Path; import org.apache.parquet.example.data.Group; import org.apache.parquet.example.data.GroupFactory; import org.apache.parquet.example.data.simple.SimpleGroupFactory; import org.apache.parquet.hadoop.ParquetFileWriter; import org.apache.parquet.hadoop.ParquetReader; import org.apache.parquet.hadoop.ParquetWriter; import org.apache.parquet.hadoop.example.ExampleParquetWriter; import org.apache.parquet.hadoop.example.GroupReadSupport; import org.apache.parquet.hadoop.metadata.CompressionCodecName; import org.apache.parquet.schema.MessageType; import org.apache.parquet.schema.MessageTypeParser; import java.io.IOException; import java.util.UUID; public class ParquetGenerator { public static void main(String... args) { MessageType schema = MessageTypeParser.parseMessageType( "message example {\n" + " required binary a (STRING);\n" + "}" ); GroupFactory factory = new SimpleGroupFactory(schema); ParquetWriter<Group> writer; try { writer = ExampleParquetWriter.builder(new Path("parquet-testing/data/hadoop_lz4_compressed_block_split.parquet")) .withWriteMode(ParquetFileWriter.Mode.CREATE) .withCompressionCodec(CompressionCodecName.LZ4) .config("io.compression.codec.lz4.buffersize", "65536") .withType(schema) .build(); for (int i = 0; i < 65536; i++) { Group group = factory.newGroup(); group.add("a", UUID.randomUUID().toString()); writer.write(group); } writer.close(); } catch (IOException e) { throw new RuntimeException(e); } } } ``` -- This is an automated message from the Apache Git Service.
