   adminWorkflow

   Configuration options for Canton admin workflows

   maxUnzippedDarSize

   maximum allowed size of unzipped DAR files (in bytes) the participant can accept for uploading. Defaults to 1GB.

   batching

   Various parameters that control batching related behavior

   minimumProtocolVersion

   The minimum protocol version that this participant will speak when connecting to a synchronizer

   initialProtocolVersion

   The initial protocol version used by the participant (default latest), e.g., used to create the initial topology transactions.

   alphaVersionSupport

   If set to true, will allow the participant to connect to a synchronizer with dev protocol version and will turn on unsafe Daml LF versions.

   dontWarnOnDeprecatedPV

   If true, then this participant will not emit a warning when connecting to a sequencer using a deprecated protocol version (such as 2.0.0).

   warnIfOverloadedFor

   If all incoming commands have been rejected due to PARTICIPANT_BACKPRESSURE during this interval, the participant will log a warning.

   ledgerApiServer

   ledger api server parameters The following specialized participant node performance tuning parameters may be grouped once a more final set of configs emerges.

   journalGarbageCollectionDelay

   How much time to delay the canton journal garbage collection

   disableUpgradeValidation

   Disable the package upgrade verification on DAR upload

   enableStrictDarValidation

   Enables the throwing of an error if lf>2.2 and the dar is not self-sufficient (i.e. throw an error if the set of included packages does not equal the set of imported packages). Normally, packages produced by damlc targeting 2.2 or above are self-sufficient. If set to false, errors are logged as warning instead.

   packageMetadataView

   Initialization parameters for the package metadata in-memory store.

   automaticallyPerformLogicalSynchronizerUpgrade

   Whether the participant automatically performs a handshake with the upgraded synchronizer after receiving enough sequencer connections, and whether the participants automatically connects to the synchronizer after the upgrade time.

   activationFrequencyForWarnAboutConsistencyChecks

   controls how often warning messages about com.digitalasset.canton.config.CantonParameters.enableAdditionalConsistencyChecks being enabled are logged, measured in the number of contract activations during a single connection to a synchronizer. Used only for database storage.

   doNotAwaitOnCheckingIncomingCommitments

   Enable fully asynchronous checking of incoming commitments. This may result in some incoming commitments not being checked in case of crashes or HA failovers.

   commitmentCheckpointInterval

   Checkpoint interval for commitments. Smaller intervals lead to less resource-intensive crash recovery, at the cost of more frequent DB writing of checkpoints. Regardless of this checkpoint interval, checkpointing is also performed at reconciliation interval boundaries.
