DowngradingConsistencyRetryPolicy Methods |
The DowngradingConsistencyRetryPolicy type exposes the following members.
Name | Description | |
---|---|---|
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
GetHashCode | Serves as the default hash function. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
OnReadTimeout |
Defines whether to retry and at which consistency level on a read timeout.
This method triggers a maximum of one retry. If less replica responsed than required by the consistency level (but at least one replica did respond), the operation is retried at a lower consistency level. If enough replica responded but data was not retrieve, the operation is retried with the initial consistency level. Otherwise, an exception is thrown. | |
OnUnavailable |
Defines whether to retry and at which consistency level on an unavailable
exception. This method triggers a maximum of one retry. If at least one replica is know to be alive, the operation is retried at a lower consistency level. | |
OnWriteTimeout |
Defines whether to retry and at which consistency level on a write timeout.
This method triggers a maximum of one retry. If writeType == WriteType.BATCH_LOG, the write is retried with the initial consistency level. If writeType == WriteType.UNLOGGED_BATCH and at least one replica acknowleged, the write is retried with a lower consistency level (with unlogged batch, a write timeout can always mean that part of the batch haven't been persisted at' all, even if receivedAcks > 0). For other writeType, if we know the write has been persisted on at least one replica, we ignore the exception. Otherwise, an exception is thrown. | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |
