When the source data keeps getting updated frequently, what is the approach to keep it in sync with the data in HDFS imported by sqoop? |
|
Answer» sqoop can have 2 approaches. a − To use the --incremental parameter with append option where value of some columns are checked and only in case of modified values the row is imported as a new row. b − To use the --incremental parameter with lastmodified option where a date column in the source is checked for records which have been updated after the last import. |
