luyuncheng opened a new pull request, #1034: URL: https://github.com/apache/lucene/pull/1034
This is derived from [LUCENE-10627](https://issues.apache.org/jira/browse/LUCENE-10627) at #987 Jira: https://issues.apache.org/jira/browse/LUCENE-10657 The abstract method `copyBytes` in DataOutput have to copy from input to a copyBuffer and then write into ByteBuffersDataOutput.blocks, i think there is unnecessary, we can override it, copy directly from input into output. with override this method, we can: 1. Reduce memory copy in `Lucene90CompressingStoredFieldsWriter#copyOneDoc` -> `bufferdDocs.copyBytes(DataInput input)` 2. Reduce memory copy in `Lucene90CompoundFormat.writeCompoundFile` -> `data.copyBytes` when input is `BufferedChecksumIndexinput` and output is `ByteBuffersDataOutput` 3. Reduce memory `IndexWriter#copySegmentAsIs` ->CopyFrom -> copyBytes -- This is an automated message from the Apache Git Service.
