Hi there,

Just notice that on this page here
https://docs.daml.com/canton/usermanual/manage_domain_entities.html#adding-new-sequencers-to-distributed-domain

It reads

For non-database-based sequencers such as Ethereum or Fabric sequencers, you can either initialize them as part of the regular distributed domain bootstrapping process or dynamically add a new sequencer at a later point as follows:

What about database based sequencers such as postgreSQL? Does it support dynamic sequencer adding?

Hi @Frankie

Database based sequencers share the same database and run in as active / active. You can just start additional replicas, without the need “onboard” them to the domain. Multiple database sequencers are logically still the same sequencer.

Please have a look at the docs here: High Availability Usage — Daml SDK 2.6.3 documentation

I hope that helps!
