<a name="avro-schema-prefix"></a>`avro_schema_prefix` | Schema prefix name | Provide a namespace for the schema of a table in addition to the default, the table name. This allows multiple databases or clusters to share the same schema registry when the same table name is present in multiple databases.<br><br>Example: `CREATE CHANGEFEED FOR foo WITH format=avro, confluent_schema_registry='registry_url', avro_schema_prefix='super'` will register subjects as `superfoo-key` and `superfoo-value` with the namespace `super`.

<a name="cursor"></a>`cursor` | [Timestamp]({% link {{ page.version.version }}/as-of-system-time.md %}#parameters) | Emit any changes after the given timestamp. `cursor` does not output the current state of the table first. When `cursor` is not specified, the changefeed starts by doing an initial scan of all the watched rows and emits the current value, then moves to emitting any changes that happen after the scan.<br><br>The changefeed will encounter an error if you specify a timestamp that is before the configured garbage collection window for the target table. (Refer to [`gc.ttlseconds`]({% link {{ page.version.version }}/configure-replication-zones.md %}#replication-zone-variables).) With default garbage collection settings, this means you cannot create a changefeed that starts more than [the-default-MVCC-garbage-collection-interval]({% link {{ page.version.version }}/configure-replication-zones.md %}#gc-ttlseconds) in the past.<br><br>You can use `cursor` to [start-a-new-changefeed-where-a-previous-changefeed-ended](#start-a-new-changefeed-where-another-ended).<br><br>Example: `cursor='1536242855577149065.0000000000'`

<a name="diff"></a>`diff` | N/A | Publish a [`before` field]({% link {{ page.version.version }}/changefeed-messages.md %}#wrapped-and-diff) with each message, which includes the value of the row before the update was applied. Changefeeds must use the `diff` option with the default [`wrapped` envelope](#envelope) to emit the `before` field.
