Footnotes 1. WAEvent must be the output of a Database Reader, Incremental Batch Reader, or SQL CDC source. 2. With an input stream of a user-defined type, output is to a single table or map. Output to multiple tables or maps requires source database metadata included in WAEvent. 3. A1P ("at-least once processing") means that after recovery there may be some duplicate events written to the target. E1P ("exactly once processing") means there will be no duplicate events. 4. If the source is WAEvent from Incremental Batch Reader, recovery is A1P. 5. Primary key updates to source rows cannot be replicated. 6. When writing to Cosmos DB, recovery is A1P. 7. Not supported when the writer's input stream is the output of Cosmos DB Reader or Mongo Cosmos DB Reader in incremental mode. 8. When the input stream is of type ParquetEvent, the writer must use Avro Formatter or Parquet Formatter. For more information, see:
