Hi Yu,
When you register a DataStream as a Table, you can create a new attribute
that contains the event timestamp of the DataStream records.
For that, you would need to assign timestamps and generate watermarks
before registering the stream:
FlinkKafkaConsumer kafkaConsumer =
new FlinkKa
Hi Jingsong,
Thanks for the reply! The following is our code snippet for creating the
log stream. Our messages are in thrift format. We use a customized
serializer for serializing/deserializing messages ( see
https://github.com/apache/flink/pull/8067 for the implementation) . Given
that, how shal

Hi @Yu Yang:
Time-based operations such as windows in both the Table API and SQL require
information about the notion of time and its origin. Therefore, tables can
offer
logical time attributes for indicating time and accessing corresponding
timestamps
in table programs.[1]
This mean Window ca
Hi,
I am trying to use Flink SQL to do aggregation on a hopping window. In the
data stream, we store the timestamp in long type. So I wrote a UDF
'FROM_UNIXTIME' to convert long to Timestamp type.
public static class TimestampModifier extends ScalarFunction {
public Timestamp eval(long t) {
