### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Paimon version 1.0 ### Compute Engine flink 1.18 ### Minimal reproduce step @Test public void testDiskUsage() throws Exception { ExternalBuffer buffer = newBuffer(MemorySize.ofKibiBytes(1)); int number = 5000; // 16 * 5000 List<Long> expected = insertMulti(buffer, number); assertThat(number).isEqualTo(buffer.size()); assertBuffer(expected, buffer); assertThat(buffer.getSpillChannels().size()).isGreaterThan(0); assertThat(buffer.flushMemory()).isFalse(); assertThat(buffer.getDiskUsage()) .isEqualTo( buffer.getSpillChannels().stream() .map( c -> { try { return Files.size( Paths.get(c.getChannel().getPath())); } catch (IOException e) { throw new RuntimeException(e); } }) .reduce(0L, Long::sum)); } ### What doesn't meet your expectations? the result of `org.apache.paimon.disk.ExternalBuffer#getDiskUsage` is much larger than actual disk usage. ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
