Subject Upgrade Snappy to 1.1.4?
Date Tue, 31 Jan 2017 18:28:34 GMT
I seem to recall that Impala uses snappy as the default codec for a lot of
compression/decompression. May be worth upgrading to the latest release
which claims a 20% improvement in decompression performance:

(just submitted a code review to Kudu to do the same, though we use LZ4
more than snappy)
