public class TableDestinationCoderV2 extends AtomicCoder<TableDestination>
Coder
for TableDestination
that includes time partitioning information. It is
the default coder for TableDestination
used by BigQueryIO
and does not extend the
old TableDestinationCoder
) for compatibility reasons. The old coder is kept around for
the same compatibility reasons.Coder.Context, Coder.NonDeterministicException

Coder

be encoded next to each other on the output stream, each coder should encode information to
know how many bytes to read when decoding. A common approach is to prefix the encoding with the
element's encoded length.encode

AtomicCoder
Coder.NonDeterministicException
if the coding is not deterministic.
In order for a Coder
to be considered deterministic, the following must be true:
Object.equals()
or Comparable.compareTo()
, if supported) have the same encoding.
Coder
always produces a canonical encoding, which is the same for an instance
of an object even if produced on different computers at different times.
Unless overridden, does not throw. An AtomicCoder
is presumed to be deterministic
