--------------------------------
Summary: Make the Compression#decompress can accept ByteBuff as
input
Key: HBASE-21937
URL: https://issues.apache.org/jira/browse/HBASE-21937
Project: HBase
Issue Type: Sub-task
Reporter: Zheng Hu
Assignee: Zheng Hu
When decompressing an compressed block, we are also allocating HeapByteBuffer
for the unpacked block. should allocate ByteBuff from the global
ByteBuffAllocator, skimmed the code, the key point is, we need an ByteBuff
decompress interface, not the following:
{code}
# Compression.java
public static void decompress(byte[] dest, int destOffset,
InputStream bufferedBoundedStream, int compressedSize,
int uncompressedSize, Compression.Algorithm compressAlgo)
throws IOException {
//...
}
{code}
Not very high priority, let me make the block without compression to be
offheap firstly.
