Interface BatchPublisherOptions

Delay before a batch insert.

With bestEffort: true (default),

• batches are inserted with write concern majority,
• the BatchPublisher will emit error events on write failures,
• retry inserting messages,
• and attempt a bulk insert on closure.

With bestEffort: false,

• batches are inserted with write concern 0,
• no errors will be emitted on failures,
• and unwritten messages will be dropped in case of failure or closure.

Maximum number of messages per batch to bulk insert.
