Abstract Value Members

  1. abstract def cleanSynchronizerIndex(synchronizerId: SynchronizerId)(connection: Connection): Option[SynchronizerIndex]

    The latest SynchronizerIndex for a synchronizerId until all events are processed fully and published to the Ledger API DB.

    The latest SynchronizerIndex for a synchronizerId until all events are processed fully and published to the Ledger API DB. The Update which from this SynchronizerIndex originate has smaller or equal offset than the current LedgerEnd: LedgerEnd and SynchronizerIndexes are persisted consistently in one transaction.

  2. abstract def initializeParameters(params: IdentityParams, loggerFactory: NamedLoggerFactory)(connection: Connection): Unit

    Initializes the parameters table and verifies or updates ledger identity parameters.

    Initializes the parameters table and verifies or updates ledger identity parameters. This method is idempotent:

    • If no identity parameters are stored, then they are set to the given value.
    • If identity parameters are stored, then they are compared to the given ones.
    • Ledger identity parameters are written at most once, and are never overwritten. No significant CPU load, mostly blocking JDBC communication with the database backend.

    This method is NOT safe to call concurrently.

  3. abstract def ledgerEnd(connection: Connection): Option[LedgerEnd]

    Query the current ledger end, read from the parameters table.

    Query the current ledger end, read from the parameters table. No significant CPU load, mostly blocking JDBC communication with the database backend.

    connection

    to be used to get the LedgerEnd

    returns

    the current LedgerEnd

  4. abstract def ledgerIdentity(connection: Connection): Option[IdentityParams]

    Returns the ledger identity parameters, or None if the database hasn't been initialized yet.

  5. abstract def participantAllDivulgedContractsPrunedUpToInclusive(connection: Connection): Option[Offset]
  6. abstract def postProcessingEnd(connection: Connection): Option[Offset]
  7. abstract def prunedUpToInclusive(connection: Connection): Option[Offset]
  8. abstract def prunedUpToInclusiveAndLedgerEnd(connection: Connection): PruneUptoInclusiveAndLedgerEnd
  9. abstract def updateLedgerEnd(ledgerEnd: LedgerEnd, lastSynchronizerIndex: Map[SynchronizerId, SynchronizerIndex] = Map.empty)(connection: Connection): Unit

    This method is used to update the new observable ledger end.

    This method is used to update the new observable ledger end. No significant CPU load, mostly blocking JDBC communication with the database backend.

    connection

    to be used when updating the parameters table

  10. abstract def updatePostProcessingEnd(postProcessingEnd: Option[Offset])(connection: Connection): Unit
  11. abstract def updatePrunedAllDivulgedContractsUpToInclusive(prunedUpToInclusive: Offset)(connection: Connection): Unit
  12. abstract def updatePrunedUptoInclusive(prunedUpToInclusive: Offset)(connection: Connection): Unit

    Part of pruning process, this needs to be in the same transaction as the other pruning related database operations
