The watermark extractor will run per Kafka partition, watermarks will be merged across partitions
in the same way as in the Flink runtime, when streams are merged.
<p>When a subtask of a FlinkKafkaConsumer source reads multiple Kafka partitions,
the streams from the partitions are unioned in a "first come first serve" fashion. Per-partition
characteristics are usually lost that way. For example, if the timestamps are strictly ascending
per Kafka partition, they will not be strictly ascending in the resulting Flink DataStream, if the
parallel source subtask reads more that one partition.
<p>Running timestamp extractors / watermark generators directly inside the Kafka source, per Kafka
partition, allows users to let them exploit the per-partition characteristics.
<p>Note: One can use either an {@link AssignerWithPunctuatedWatermarks} or an
{@link AssignerWithPeriodicWatermarks}, not both at the same time.

... | Returns the calendar interval type value for rowId. If the slot for rowId is null, it should
return null.
In Spark, calendar interval type value is basically an integer value representing the number of
months in this interval, and a long value representing the number of microseconds in this
interval. An interval type vector is the same as a struct type vector with 2 fields: `months`
and `microseconds`.
To support interval type, implementations must implement {@link #getChild(int)} and define 2
child vectors: the first child vector is an int type vector, containing all the month values of
all the interval values in this vector. The second child vector is a long type vector,
containing all the microsecond values of all the interval values in this vector. | [

Please see FLINK-11436 for details on why manual deserialization is required.
During the release of Flink 1.7, the value of serialVersionUID was uptick to 2L (was 1L before)
And although the AvroSerializer (along with it's snapshot class) were migrated to the new serialization
abstraction (hence free from Java serialization), there were composite serializers that were not migrated
and were serialized with Java serialization. In case that one of the nested serializers were Avro we would
bump into deserialization exception due to a wrong serialVersionUID. Unfortunately it is not possible to revert
the serialVersionUID back to 1L, because users might have snapshots with 2L present already.
To overcome this we first need to make sure that the AvroSerializer is being Java deserialized with
FailureTolerantObjectInputStream, and then we determine the serialized layout by looking at the fields.

null or a string, but, in post 1.7, the field @previousSchema was never set to null, therefore
we can use the first field to determine the version.
