taherk77 commented on issue #917: [HUDI-251] JDBC incremental load to HUDI with 
DeltaStreamer
URL: https://github.com/apache/incubator-hudi/pull/917#issuecomment-533891750
 
 
   https://sqoop.apache.org/docs/1.4.2/SqoopUserGuide.html#_incremental_imports 
 mentions --last_value. I think we should be computing that within the source. 
My vision is once the user specifies the incremental column and the interval we 
should be pulling the data every interval. 
   
   so in short deltastreamer will never get shut down unless it is manually 
shut and will keep pulling new data from the JDBC source. 
   
   The other option is that when we set is_incremental as false then we pull 
all the data at once and then write it.
