chenfengge updated HBASE-27049:
-------------------------------
Description: HBase RegionServer use createDecompressionStream in class
org.apache.hadoop.hbase.io.compress.Compression, which cause extra memory copy
during decompression.We can offer interface for block decompression, like "void
decompress(ByteBuff src, ByteBuff dst);", and offer default implementation for
all algorithms. (was: HBase RegionServer use createDecompressionStream in
class[
