Hi Enrico,
that's the default setting for the broker. You can also dynamically
override the setting for a particular namespace.
eg.:
bin/pulsar-admin namespaces set-persistence \
public/default \
--bookkeeper-ensemble 3 \
--bookkeeper-write-quorum 3 \
--bookkeeper-ack-quorum 2 \
--ml-mark-delete-max-rate 1.0
The change is automatically applied to new ledgers at the next ledger rollover.
(You can also force a rollover by reloading the topic: pulsar-admin
topics unload $TOPIC )
