[GitHub] [beam] damccorm opened a new issue, #21664: Optimize copies in dataflow v1 shuffle reader
damccorm opened a new issue, #21664:
URL: https://github.com/apache/beam/issues/21664
The dataflow v1 shuffle reader unnecessarily copies the byte[] read from shuffle, we could use something like ByteString to instead "slice" the buffer into pieces and avoid a few copies.
Imported from Jira [BEAM-14545](https://issues.apache.org/jira/browse/BEAM-14545). Original Jira may contain additional context.
