JDBC Extractor version 2.94.0 (2024-04-08)

Delta loads now default to canceling if the metadata has changed

For this version of the JDBC Extractor, we’ve fixed some issues with the recommended metadata change handling option while configuring delta extractions.

• With the default option (Option A), the delta load is canceled if the metadata from your source system changes compared to the already extracted data (for example, if new columns are added). You’ll need to do a full load or change the affected table manually.
• With the alternative option (Option , the delta load runs with a warning message, but data for the new columns only appears in the newly loaded rows. Rows that aren’t in the delta load get null values in the new columns. Some users prefer this approach, but it does introduce a data inconsistency, and you should do a full load after getting this warning.
