Never to perform snapshot on the monitored database tables upon first startup, and directly
read binlog from the specified timestamp.

<p>The consumer will traverse the binlog from the beginning and ignore change events whose
timestamp is smaller than the specified timestamp.</p>

@param startupTimestampMillis timestamp for the startup offsets, as milliseconds from epoch.
