Collecting discarded events in an exception store

When replicating CDC source data with Azure Synapse Writer, BigQuery Writer, Cosmos DB Writer, Database Writer, Databricks Writer, MongoDB Cosmos DB Writer, MongoDB Writer, or Spanner Writer, attempted updates to and deletes from the target database may sometimes fail due to missing tables, duplicate or missing primary keys, or other issues. See CREATE EXCEPTIONSTORE for discussion of how to ignore these errors and capture the unwritten events.
