------------------------------------
Summary: Consolidate CompositeByteBuf when reading large frame
Key: SPARK-26674
URL: https://issues.apache.org/jira/browse/SPARK-26674
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.4.0
Reporter: liupengcheng
Currently, TransportFrameDecoder will not consolidate the buffers read from
network which may cause memory waste. Actually, bytebuf's writtenIndex is far
less than it's capacity in most cases, so we can optimize it by doing
consolidation.
