Various database related settings
- maxConnections
Allows for setting the maximum number of db connections used by Canton and the ledger API server. If None or non-positive, the value will be auto-detected from the number of processors. Has no effect, if the number of connections is already set via slick options (i.e.,
config.numThreads).- failFastOnStartup
If true, the node will fail-fast when the database cannot be connected to If false, the node will wait indefinitely for the database to come up
- ledgerApiJdbcUrl
Canton attempts to generate appropriate configuration for the daml ledger-api to persist the data it requires. In most circumstances this should be sufficient and there is no need to override this. However if this generation fails or an advanced configuration is required, the ledger-api jdbc url can be explicitly configured using this property. The jdbc url **must** specify the schema of
ledger_api(using h2 parameterschemaor postgres parametercurrentSchema). This property is not used by a domain node as it does not run a ledger-api instance, and will be ignored if the node is configured with in-memory persistence.- connectionTimeout
How long to wait for acquiring a database connection
- warnOnSlowQuery
Optional time when we start logging a query as slow.
- warnOnSlowQueryInterval
How often to repeat the logging statement for slow queries.
- unsafeCleanOnValidationError
TO BE USED ONLY FOR TESTING! Clean the database if validation during DB migration fails.
- unsafeBaselineOnMigrate
TO BE USED ONLY FOR TESTING! Whether to automatically call baseline when migrate is executed against a non-empty schema with no schema history table. This schema will then be baselined with the
baselineVersionbefore executing the migrations. Only migrations abovebaselineVersionwill then be applied. This is useful for databases projects where the initial vendor schema is not empty If baseline should be called on migrate for non-empty schemas, { @code false} if not. (default: { @code false})
