Aggregator configuration

Fields

environment: ExecutionEnvironment

What kind of runtime environment the configuration is meant to.

cardano_cli_path: PathBuf

Cardano CLI tool path

cardano_node_socket_path: PathBuf

Path of the socket used by the Cardano CLI tool to communicate with the Cardano node

cardano_node_version: String

Cardano node version.

NOTE: This cannot be verified for now (see this issue). This is why it has to be manually given to the Aggregator

network_magic: Option<u64>

Cardano Network Magic number

useful for TestNet & DevNet

network: String

Cardano network

chain_observer_type: ChainObserverType

Cardano chain observer type

protocol_parameters: ProtocolParameters

Protocol parameters

snapshot_uploader_type: SnapshotUploaderType

Type of snapshot uploader to use

snapshot_bucket_name: Option<String>

Bucket name where the snapshots are stored if snapshot_uploader_type is Gcp

snapshot_use_cdn_domain: bool

Use CDN domain to construct snapshot urls if snapshot_uploader_type is Gcp

server_ip: String

Server listening IP

server_port: u16

Server listening port

run_interval: u64

Run Interval is the interval between two runtime cycles in ms

db_directory: PathBuf

Directory of the Cardano node store.

snapshot_directory: PathBuf

Directory to store snapshot

data_stores_directory: PathBuf

Directory to store aggregator data (Certificates, Snapshots, Protocol Parameters, …)

genesis_verification_key: HexEncodedGenesisVerificationKey

Genesis verification key

reset_digests_cache: bool

Should the immutable cache be reset or not

disable_digests_cache: bool

Use the digest caching strategy

store_retention_limit: Option<usize>

Max number of records in stores. When new records are added, oldest records are automatically deleted so there can always be at max the number of records specified by this setting.

era_reader_adapter_type: EraReaderAdapterType

Era reader adapter type

era_reader_adapter_params: Option<String>

Era reader adapter parameters

signed_entity_types: Option<String>

Signed entity types parameters (discriminants names in an ordered, case-sensitive, comma separated list).

The values MithrilStakeDistribution and CardanoImmutableFilesFull are prepended automatically to the list.

snapshot_compression_algorithm: CompressionAlgorithm

Compression algorithm used for the snapshot archive artifacts.

zstandard_parameters: Option<ZstandardCompressionParameters>

Specific parameters when snapshot_compression_algorithm is set to zstandard.

cexplorer_pools_url: Option<String>

Url to CExplorer list of pools to import as signer in the database.

signer_importer_run_interval: u64

Time interval at which the signers in Self::cexplorer_pools_url will be imported (in minutes).

allow_unparsable_block: bool

If set no error is returned in case of unparsable block and an error log is written instead.

Will be ignored on (pre)production networks.

cardano_transactions_prover_cache_pool_size: usize

Cardano transactions prover cache pool size

cardano_transactions_database_connection_pool_size: usize

Cardano transactions database connection pool size

cardano_transactions_signing_config: CardanoTransactionsSigningConfig

Cardano transactions signing configuration

cardano_transactions_prover_max_hashes_allowed_by_request: usize

Maximum number of transactions hashes allowed by request to the prover of the Cardano transactions

cardano_transactions_block_streamer_max_roll_forwards_per_poll: usize

The maximum number of roll forwards during a poll of the block streamer when importing transactions.

enable_metrics_server: bool

Enable metrics server (Prometheus endpoint on /metrics).

metrics_server_ip: String

Metrics HTTP Server IP.

metrics_server_port: u16

Metrics HTTP Server listening port.

persist_usage_report_interval_in_seconds: u64

Time interval at which usage metrics are persisted in event database (in seconds).

Implementations

impl Configuration

pub fn new_sample() -> Self

Create a sample configuration mainly for tests

pub fn get_server_url(&self) -> String

Build the server URL from configuration.

pub fn get_network(&self) -> StdResult<CardanoNetwork>

Check configuration and return a representation of the Cardano network.

pub fn get_sqlite_dir(&self) -> PathBuf

Return the file of the SQLite stores. If the directory does not exist, it is created.

pub fn safe_epoch_retention_limit(&self) -> Option<u64>

Same as the store retention limit but will never yield a value lower than 3.

This is in order to avoid pruning data that will be used in future epochs (like the protocol parameters).

pub fn compute_allowed_signed_entity_types_discriminants( &self, ) -> StdResult<BTreeSet<SignedEntityTypeDiscriminants>>

Compute the list of signed entity discriminants that are allowed to be processed based on this configuration.

Trait Implementations

impl Clone for Configuration

fn clone(&self) -> Configuration

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Configuration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Configuration

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Documenter for Configuration

fn extract() -> StructDoc

Extract information used to generate documentation.

impl Serialize for Configuration

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>
