The next version will be Data Pipeline vs API: what’s the difference? It does not use HTTP (though it still does use JSON), and it is slightly more involved to integrate, but it opens If surrogate key does not exist, add a new entry to the mapping table, add a new record to the target table, and increment the maximum key by 1. Example Queries: SELECT IntKey, PARSETIMESTAMP(timestampvalue, 'yyyy-MM-dd HH:mm:ss') FROM Source. This tutorial provides examples of how to automate the download and import of User DB data sets from Swrve. Only if etl_tstamp does not exist in the load manifest will the data be moved over to the atomic.


it has no effect in Amazon Redshift. Tungsten Replicator does not replicate the DDL statements between the source and applier between heterogenous deployments due to differences in the format of the DDL statements.
