Properties

BatchSendFrequency

Gets or sets the batch send frequency.

GridGain accumulates entries until either count reaches BatchSendSize or time reaches BatchSendFrequency.

Declaration

public TimeSpan BatchSendFrequency { get; set; }

Property Value

Type	Description
TimeSpan

BatchSendSize

Gets or sets the size of the batch to send.

GridGain accumulates entries until either count reaches BatchSendSize or time reaches BatchSendFrequency.

Declaration

public int BatchSendSize { get; set; }

Property Value

Type	Description
System.Int32

EntryFilter

Gets or sets the entry filter.

When set it will be applied to all entries which are candidates for data center replication. If the filter is not passed, data center replication will not be performed on that entry.

Declaration

public ICacheDrEntryFilter EntryFilter { get; set; }

Property Value

Type	Description
ICacheDrEntryFilter

LoadBalancingMode

Gets or sets the load balancing mode. When batch is ready to be sent, this parameter defines how to select the next sender hub this batch will be sent to.

Declaration

public DrSenderLoadBalancingMode LoadBalancingMode { get; set; }

Property Value

Type	Description
DrSenderLoadBalancingMode

MaxBackupQueueSize

Gets or sets the maximum size of the backup queue. Ignored when less than or equal to 0.

To support failover, GridGain tracks replicated entries on backup nodes in a bounded queue. By default this queue size is calculated based on maximum amount of batches MaxBatches, batch send size BatchSendSize, and number of backup nodes Backups.

Set this property to a positive value to control queue size manually.

Declaration

public int MaxBackupQueueSize { get; set; }

Property Value

Type	Description
System.Int32

MaxBatches

Gets or sets the maximum amount of batches awaiting for sender hub acknowledge. When amount of batches awaiting sender hub delivery acknowledge reaches this value, all further cache updates will be suspended until it is below the limit again.

Declaration

public int MaxBatches { get; set; }

Property Value

Type	Description
System.Int32

PreferLocalSender

Gets or sets a value indicating whether local sender hub should be preferred, ignoring the load balancing policy.

Declaration

public bool PreferLocalSender { get; set; }

Property Value

Type	Description
System.Boolean

SenderGroup

Gets or sets a sender group that will be used for replication.

Declaration

public string SenderGroup { get; set; }

Property Value

Type	Description
System.String

StateTransferThreadsCount

Gets or sets the state transfer threads count.

Declaration

public int StateTransferThreadsCount { get; set; }

Property Value

Type	Description
System.Int32

StateTransferThrottle

Gets or sets the state transfer throttle. Defines delay to wait between full state transfer batches creation to avoid CPU or network overload.

Declaration

public TimeSpan StateTransferThrottle { get; set; }

Property Value

Type	Description
TimeSpan
