Last
Last will start the consumer with the last sequence received.
New
New will only deliver new messages that are received by the JetStream
server
after the consumer is created.
ByStartSeq
ByStartSeq
will look for a defined starting sequence to the consumer’s configured opt_start_seq
parameter.
ByStartTime
ByStartTime
will select the first messsage with a timestamp >= to the consumer’s
configured opt_start_time
parameter.
LastPerSubject
LastPerSubject
will start the consumer with the last message
for all subjects received.
