    • isLazyCursorRecovery

      public boolean isLazyCursorRecovery()
      返回:
      the lazyCursorRecovery

    • setLazyCursorRecovery

      public ManagedLedgerConfig setLazyCursorRecovery(boolean lazyCursorRecovery)
      Whether to recover cursors lazily when trying to recover a managed ledger backing a persistent topic. It can improve write availability of topics. The caveat is now when recovered ledger is ready to write we're not sure if all old consumers last mark delete position can be recovered or not.
      参数:
      lazyCursorRecovery - if enable lazy cursor recovery.

    • getMaxEntriesPerLedger

      public int getMaxEntriesPerLedger()

    • getMinimumRolloverTimeMs

      public int getMinimumRolloverTimeMs()
      返回:
      the minimum rollover time

    • setMinimumRolloverTime

      public void setMinimumRolloverTime(int minimumRolloverTime, TimeUnit unit)
      Set the minimum rollover time for ledgers in this managed ledger.

      If this time is > 0, a ledger will not be rolled over more frequently than the specified time, even if it has reached the maximum number of entries or maximum size. This parameter can be used to reduce the amount of rollovers on managed ledger with high write throughput.

      参数:

      Set the maximum rollover time for ledgers in this managed ledger.

      If the ledger is not rolled over until this time, even if it has not reached the number of entry or size limit, this setting will trigger rollover. This parameter can be used for topics with low request rate to force rollover, so recovery failure does not have to go far back.

      参数:
      maximumRolloverTime - the maximum rollover time
      unit - the time unit
