----------------------------------------
Summary: Allow NettyBufferPool to allocate heap buffers
Key: FLINK-18695
URL: https://issues.apache.org/jira/browse/FLINK-18695
Project: Flink
Issue Type: Improvement
Components: Runtime / Network
Reporter: Chesnay Schepler
Fix For: 1.12.0
in 4.1.43 netty made a change to their SslHandler to always use heap buffers
for JDK SSLEngine implementations, to avoid an additional memory copy.
However, our {{NettyBufferPool}} forbids heap buffer allocations.
We will either have to allow heap buffer allocations, or create a custom
SslHandler implementation that does not use heap buffers (although this seems
ill-adviced?).
