   Configuration for exclusive database sequencer storage

   Configuration for exclusive database sequencer storage

   connectionPool

   configuration of the exclusive write connection pool.

   maxConnections

   maximum read plus write connections.

4.  final case class EnterpriseSequencerReaderConfig(readBatchSize: Int = SequencerReaderConfig.defaultReadBatchSize, checkpointInterval: NonNegativeFiniteDuration = SequencerReaderConfig.defaultCheckpointInterval, pollingInterval: NonNegativeFiniteDuration = NonNegativeFiniteDuration.ofMillis(100)) extends SequencerReaderConfig with Product with Serializable

   Configuration for the database based sequence reader in enterprise.

   Configuration for the database based sequence reader in enterprise.

   pollingInterval

   how frequently to poll for new events from the database. only used if high availability has been configured, otherwise will rely on local writes performed by this sequencer to indicate that new events are available.

5.  final case class External(sequencerType: String, config: ConfigCursor) extends EnterpriseSequencerConfig with Product with Serializable
6.  final case class SequencerHighAvailabilityConfig(enabled: Option[Boolean] = None, totalNodeCount: PositiveInt = PositiveInt.tryCreate(10), keepAliveInterval: NonNegativeFiniteDuration = NonNegativeFiniteDuration.ofMillis(100L), onlineCheckInterval: NonNegativeFiniteDuration = NonNegativeFiniteDuration.ofSeconds(5L), offlineDuration: NonNegativeFiniteDuration = NonNegativeFiniteDuration.ofSeconds(8L), connectionPool: DbLockedConnectionPoolConfig = DbLockedConnectionPoolConfig(), exclusiveStorage: DatabaseSequencerExclusiveStorageConfig = DatabaseSequencerExclusiveStorageConfig()) extends Product with Serializable

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

   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.

7.  final case class SequencerPruningConfig(maxPruningBatchSize: PositiveInt = PositiveInt.tryCreate(50000), pruningMetricUpdateInterval: Option[PositiveDurationSeconds] = PositiveDurationSeconds.ofHours(1L).some, unauthenticatedMemberRetention: NonNegativeFiniteDuration = NonNegativeFiniteDuration.ofHours(1)) extends Product with Serializable

   Configuration for enterprise sequencer pruning

   Configuration for enterprise sequencer pruning

   maxPruningBatchSize

   maximum number of events to prune from a sequencer at a time, used to break up batches internally

   pruningMetricUpdateInterval

   How frequently to update the max-event-age pruning progress metric in the background. A setting of None disables background metric updating.

   unauthenticatedMemberRetention

   retention duration on how long to retain unauthenticated sequencer members that would otherwise block sequencer pruning. Unauthenticated members older than the specified retention will be automatically disabled.
