Subject support for zero copy reads
Date Fri, 22 Sep 2017 22:15:41 GMT
Hi, does HBase take advantage of HDFS zero copy reads?
My idea is that RegionServers could potentially mmap everything they need
via the HDFS ZCR API and pass SKIP_CHECKSUMS when reading files via mmap,
since HBase supports its own checksumming on the HFile level... correct?

Could be completely wrong... Hence the open question.
