   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.

   contractIdSeeding

   test-only way to override the contract-id seeding scheme. Must be Strong in production (and Strong is the default). Only configurable to reduce the amount of secure random numbers consumed by tests and to avoid flaky timeouts during continuous integration. The following specialized participant node performance tuning parameters may be grouped once a more final set of configs emerges.

   indexer

   parameters how the participant populates the index db used to serve the ledger api

   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

   uniqueContractKeys

   Whether the participant can connect only to a single domain that has com.digitalasset.canton.protocol.StaticDomainParameters.uniqueContractKeys set

   unsafeEnableDamlLfDevVersion

   If set to true (default false), packages referring to the dev LF version can be used with Canton.

   willCorruptYourSystemDevVersionSupport

   If set to true, development protocol versions (and database schemas) will be supported. Do NOT use this in production, as it will break your system.

   warnIfOverloadedFor

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