client Table instance, confused with autoFlush

Hi, in 0.94 we could use autoFlush method for HTable.
Now HTable shouldn't be used, we refactoring code for Table

Here is a note:
http://hbase.apache.org/book.html#perf.hbase.client.autoflush
>When performing a lot of Puts, make sure that setAutoFlush is set to false
on your Table
<http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/Table.html>
 instance

What is the right way to set autoFlush for Table instance? Can't find
method/example to do this?

Until you move to HBase 1.*, you should use HTableInterface. And the
autoFlush methods and semantics, as far as I understand are, same so you
should not have problem.

The docs you referenced are for 1.0.  Table and BufferedMutator were
introduced in 1.0.  In 0.98, you should continue using HTable and
autoflush.

BufferedMutator is the preferred alternative for autoflush starting in
HBase 1.0.  Get a connection via ConnectionFactory, then
connection.getBufferedMutator(tableName).  It's the same functionality as
autoflush under the covers.
