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.

Re: client Table instance, confused with autoFlush

[Solomon Duskis]

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.

But HTable is deprecated in 0.98 ...?

Re: client Table instance, confused with autoFlush

[Shahab Yunus]

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.
