Description

1. Add the following aggregation functions to Sedona, just like Sedona Spark

ST_Envelope_Aggr

ST_Union_Aggr

 

2. enable event time and proc time in all synthetic test data

All test tables now have two time attributes, namely "event_time", "proc_time"

 

The 2 attributes can be used in Flink window queries.
