The name of the PostgreSQL logical decoding slot that was created for streaming changes from
a particular plug-in for a particular database/schema. The server uses this slot to stream
events to the connector that you are configuring. Default is "flink".

<p>Slot names must conform to <a
href="https://www.postgresql.org/docs/current/static/warm-standby.html#STREAMING-REPLICATION-SLOTS-MANIPULATION">PostgreSQL
replication slot naming rules</a>, which state: "Each replication slot has a name, which can
contain lower-case letters, numbers, and the underscore character."
