Configuration for how many sequencers are concurrently operating within the domain.

enabled

Set to Some(true) to enable HA for the sequencer. If None it will be enabled if the storage supports replication.

totalNodeCount

how many sequencer writers will there ever be in this domain. recommend setting to a value larger than the current topology to allow for expansion.

keepAliveInterval

how frequently will we ensure the sequencer watermark is updated to ensure it still appears alive

onlineCheckInterval

how frequently should this sequencer check that nodes are still online

offlineDuration

how long should a sequencer watermark be lagging for it to be flagged as offline

connectionPool

configuration of the write connection pool used by an HA sequencer instance.
