Lars Hofhansl updated HBASE-7008:
---------------------------------
Release Note:
This patch increases the default scanner caching to 100.
It also enables tcpNoDelay by default (i.e. disabled Nagle's algorithm).
This will generally lead to better performance, but in some situation may lead
to different network patterns and increase memory consumption on both the
client and the server.
How's this for a release note?
