   adminWorkflow

   Configuration options for Canton admin workflows

   partyChangeNotification

   Determines how eagerly the participant nodes notify the ledger api of party changes. By default ensure that parties are added via at least one domain before ACKing party creation to ledger api server indexer. This not only avoids flakiness in tests, but reflects that a party is not actually usable in canton until it's available through at least one domain.

   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

   transferTimeProofFreshnessProportion

   Proportion of the target domain exclusivity timeout that is used as a freshness bound when requesting a time proof. Setting to 3 means we'll take a 1/3 of the target domain exclusivity timeout and potentially we reuse a recent timeout if one exists within that bound, otherwise a new time proof will be requested. Setting to zero will disable reusing recent time proofs and will instead always fetch a new proof.

   minimumProtocolVersion

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

   initialProtocolVersion

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

   devVersionSupport

   If set to true, will allow the participant to connect to a domain 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.

   ledgerApiServerParameters

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

   excludeInfrastructureTransactions

   If set, infrastructure transactions (i.e. ping, bong and dar distribution) will be excluded from participant metering.

   enableEngineStackTraces

   If true, DAMLe stack traces will be enabled

   enableContractUpgrading

   If true contracts may be automatically upgraded or downgraded as needed.

   iterationsBetweenInterruptions

   Number of engine iterations between forced interruptions (outside needs of information).
