^[a]Supporting replication means that the target can replicate insert, update, and delete events from the source. ^[b]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. ^[c]When the input stream is of type ParquetEvent, the writer must use Avro Formatter or Parquet Formatter. ^[d]If the source is WAEvent from Incremental Batch Reader, recovery is A1P. ^[e]WAEvent must be the output of a Database Reader, Incremental Batch Reader, or SQL CDC source. ^[f]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. ^[g]Primary key updates to source rows cannot be replicated. ^[h]Primary key updates to source rows cannot be replicated. ^[i]Not supported when the writer's input stream is the output of Cosmos DB Reader or Mongo Cosmos DB Reader in incremental mode. ^[j]WAEvent must be the output of a Database Reader, Incremental Batch Reader, or SQL CDC source. ^[k]When the input stream is of type ParquetEvent, the writer must use Avro Formatter or Parquet Formatter. ^[l]See notes for the Checkpoint Collection property.
