public AppendFiles newFastAppend()

Description copied from interface: Table

Create a new append API to add files to this table and commit.

Using this method signals to the underlying implementation that the append should not perform extra work in order to commit quickly. Fast appends are not recommended for normal writes because the fast commit may cause split planning to slow down over time.

Implementations may not support fast appends, in which case this will return the same appender as Table.newAppend().
