• DatabaseOptions

  public DatabaseOptions(OptionConsumer consumer)

Method Detail

• setLocationCacheSize

  public void setLocationCacheSize(long value)

  Set the size of the client location cache. Raising this value can boost performance in very large databases where clients access data in a near-random pattern. Defaults to 100000.

  Parameters:

  value - Max location cache entries

• setMaxWatches

  public void setMaxWatches(long value)

  Set the maximum number of watches allowed to be outstanding on a database connection. Increasing this number could result in increased resource usage. Reducing this number will not cancel any outstanding watches. Defaults to 10000 and cannot be larger than 1000000.

  Parameters:

  value - Max outstanding watches

• setMachineId

  public void setMachineId(String value)

  Specify the machine ID that was passed to fdbserver processes running on the same machine as this client, for better location-aware load balancing.

  Parameters:

  value - Hexadecimal ID

• setDatacenterId

  public void setDatacenterId(String value)

  Specify the datacenter ID that was passed to fdbserver processes running in the same datacenter as this client, for better location-aware load balancing.

  Parameters:

  value - Hexadecimal ID

• getOptionConsumer

  public OptionConsumer getOptionConsumer()

  Returns the object on which these options are being set. Rarely used by client code, since all options should be top-level methods on extending classes.

  Returns:

  target of option set calls
