--------------------------------------
Summary: [hsync] Output stream should support direct byte buffer
Key: HDDS-10361
URL: https://issues.apache.org/jira/browse/HDDS-10361
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Wei-Chiu Chuang
I'm trying to cherrypick HDDS-9843. Ozone client high memory (heap) utilization
(#6153) from master to HDDS-7593 dev branch. But it's giving me this error
{noformat}
Failed to flush. error: null

The incremental chunk list feature assumes heap byte buffer. But HDDS-9843
requires direct byte buffer. We should leverage direct byte buffer.
